Introduction
Welcome
00:04Brian Liepe: Welcome to this training series, where we are going to get you all the info
00:07you need to shoot great video with a DSLR camera.
00:10Chad Perkins: My name is Chad Perkins and this here is Brian Liepe, the best cinematographer,
00:17and camera person, and lighting person that I have ever seen in my entire life.
00:23And we are extremely excited to show you the ins and outs of these amazing cameras.
00:27Brian Liepe: Several years ago, Chad and I were both shooting with these much more expensive
00:33cameras in order to get the same beautiful shots that these DSLR cameras can.
00:39We needed a lot more light and a lot more gear.
00:42When DSLRs came out, it sparked a huge revolution in the world of video. That huge rig cost almost $10,000.
00:50This little camera gets more cinematic footage and less light with less weight and for $500.
00:56Brian Liepe: In this training we are going to start from scratch with the basics of cinematography
01:03and using different lenses.
01:04Chad Perkins: From there, we will share with you our experience in using these cameras
01:09on set and also in postproduction, including some of the problems that we've encountered
01:16and what can be done to resolve them.
01:18Brian Liepe: This course is going to be a great education and tons of fun, so let's get started.

About the camera used in this course
00:00Chad Perkins: There are many great choices out there for DSLR cameras.
00:03Nikon makes great cameras like the D800. Panasonic makes the fantastic GH2.
00:09Brian Liepe: But by far, the most popular DSLR used in video are the cameras made by Canon.
00:15Specifically the Canon 5D Mark II which this is being shot on and the Canon 70, for that
00:21reason those are the cameras we will be using.
00:24Chad Perkins: The tutorials for this, as Brian mentioned, are being shot with a Canon 5D Mark
00:29II, but we will also be seeing footage throughout this course with the Canon 7D and this Canon T2i.
00:36Regardless of which camera you are using, the concepts in this training series are almost
00:41always going to be applicable to all DSLRs that shoot video.

1. Photography Basics
Understanding photography
00:00Chad Perkins: Before we get into issues specific to DSLR cameras we need to first talk about
00:04the basics of photography, which are also the basics of cinematography.
00:08Brian Liepe: The three fundamental concepts we are going to cover in this chapter are
00:12aperture, shutter speed and ISO.
00:15Each of these work together to achieve proper exposure or brightness level.
00:19Chad Perkins: With each of these three attributes there are pros and cons, and as we go
00:24throughout this chapter we are going to learn what each of those things are and how to balance
00:28those, how to balance those trade offs to adjust exposure.
00:31Brian Liepe: Learning to balance aperture, shutter speed and ISO is really where you
00:36get to become an artist when working with your DSLR.
00:39Let's dig a little bit deeper into these three fundamental concepts.

Understanding aperture
00:00Brian Liepe: Okay, so one of the most effective ways to adjust your exposure in your camera
00:05is by adjusting the aperture.
00:07The aperture is a mechanism inside the lens that's made up of a series of blades that
00:11either let light in or keep it out.
00:14Now you usually interface with this aperture through your camera.
00:17Chad Perkins: The openness of the aperture is measured using a degree of measurement
00:22called an f-stop.
00:24Now because aperture is a function of the lens exact settings will vary from lens to lens.
00:31Now another feature of aperture is it controls focus, so in other words your depth of field,
00:36and we will talk about that a little bit later.
00:38Brian Liepe: The unit of measurement that represents the size of your aperture is called an f-stop.
00:42That can be a little bit tricky because the lower the f- stop number, the bigger the aperture, and vice versa.
00:47The higher the f-stop number, the smaller the aperture.
00:52Now we've covered the basics of aperture, but if you're curious, we are going to explain
00:56a little bit more about the technical details regarding f-stops.
00:59Chard Perkins: The reason why f-stops increase as the size of the aperture decreases is that
01:05because F stands for fraction.
01:09So if you have an f-stop of f/4, this really means that the aperture is open to one fourth
01:15of the size of the focal length of the lens.
01:18Brian Liepe: So if we had a 100 mm lens and our f-stop was a value of f/4, the aperture
01:25diameter would be 25 mm.
01:28If we increase the f-stop to f/8 on the same lens, we are now closing the aperture to 1/8th
01:34of its focal length.
01:35So the diameter of the aperture is now 12.5 mm.
01:38Chad Perkins: In the next tutorial, we will look a little bit more closely at how aperture
01:43relates to focus.
01:45We will also look at some of the pros and cons of adjusting your exposure by using your aperture.

Trade-offs with aperture adjustment
00:00Chad Perkins: Personally my favorite way to adjust exposure using the camera is with aperture.
00:05Brian Liepe: Yeah, it's a great way to adjust exposure because it's optical and not electronic,
00:11like shutter speed or ISO.
00:13You'll typically get better results from optical adjustments.
00:16Chad Perkins: One of the cool tricks with aperture is that if we open it up, we let
00:21a lot of light into the scene.
00:24In this shot there really isn't much light but because the aperture is open all the way,
00:28and also because DSLR cameras are super sensitive to light, the shot looks great.
00:33Brian Liepe: Yeah that shot is pretty cool but you'll notice that the objects in the
00:37foreground or the objects just in front of your subject and the objects just behind your
00:41subjects are out of focus.
00:44And that's what happens when you open up your aperture, your depth of field decreases, which
00:49means your plane of focus becomes more narrow.
00:51So the distance in which objects are in focus becomes more narrow.
00:56Chad Perkins: So let's take a look at these spheres.
00:59Let's say that I wanted just one of these spheres in focus.
01:03What I would do in the real- world is I would open up my aperture.
01:07This reduces the in-focus area to a very shallow plane allowing me to focus on just this one sphere.
01:14Brian Liepe: All right Chad, nice spheres, but let's looks at a real-world example.
01:20In this shot, I'm shooting with my aperture wide open, you can see that my subject is
01:24in focus but everything beyond my subject is out of focus completely.
01:29Now I'm going to dial down my aperture in this next shot and you can see that everything
01:35is in focus. I've got great depth of field.
01:40Now you're probably wondering, well if I adjusted my aperture so much, why is my exposure looking
01:46pretty similar in each shot?
01:48Well that's because I'm using something called a variable neutral density filter and we'll
01:53talk about those a little bit later on.
01:54Chad Perkins: Now one of the things that I'm noticing here is that in this shot where the
01:58aperture is wide open, everything seems a little bit softer and has less contrast than
02:04the other shot where the aperture is more closed.
02:06Brian Liepe: Yeah, there is an old adage that says for any lens it will be most sharp two
02:12stops down and lower from wide-open.
02:15Chad Perkins: So in other words, when your aperture is wide-open and also just one stop
02:21down from that, it's going to be a little bit softer then when the aperture is closed
02:25the rest of the way.
02:27So as you can see, aperture is a great way to adjust exposure, but there are some trade-offs.

Understanding shutter speed
00:00Brian Liepe: Videos comprised of series of stills, whether you're shooting stills or
00:04video, there is a digital shutter that allows light to enter each frame.
00:09Now back in the day, film cameras had a rotary shutter disk and there was a wedge cut out of it.
00:15Now the degree to which that wedge was open determined how long each frame was exposed.
00:22In these cameras, shutter angle was measured by degrees.
00:25Chad Perkins: DSLR's usually measure shutter speed in units of time, typically fractions of one second.
00:33Now if you slow down your shutter speed, you will increase exposure because you're letting
00:38more light into the camera that hits the sensor.
00:42But your motion blur will also be affected which we'll talk about a little bit later.
00:46Brian Liepe: As a standard, our frame rate determines our shutter speed, and now that
00:51we've learned that our shutter speed is measured in time, a fraction of one second, we can
00:56take the denominator in that fraction and make sure that it's double our frame rate.
01:01So if you are shooting at 24 frames per second, your shutter speed should be 1/48.
01:05If you're your shooting at 30 frames per second, your shutter speed should be 1/60.
01:11These DSLRs don't quite get to 1/48 if you are shooting at 24 frames per second, so 1/50
01:18will do just fine.
01:20So we'll learn more about shutter speed and how it affects motion blur and exposure in
01:24the next movie.
Collapse this transcript
Trade-offs with shutter adjustment
00:00Chad Perkins: Shutter speed is another way to adjust exposure but I almost never fiddle
00:04with it. I usually keep it set at 1/50th of a second, because I usually shoot 24 frames
00:10per second. Sometimes if I shoot 30 frames per second I'll go up to 1/60th, and if I'm going
00:15to do slow motion, 60 frames per second, I would do 1/120th of a second, but these cameras
00:20typically only go to 1/125th of a second, so I leave it set there.
00:25And the reason why I don't adjust the shutter speed that much is because of how it affects the motion blur.
00:31Brian Liepe: Right, so motion blur is the streaking or smearing of quickly moving objects
00:36in a photograph or video.
00:37It's a totally natural thing and it smooths motion from frame to frame and even though
00:43it may not be obvious, our vision contains some motion blur.
00:46Chad Perkins: So shutter speed affects motion blur and exposure.
00:51For example, if I were to speed up the shutter speed then that's going to make the action
00:56crisp because it decreases the motion blur, but it also lowers the exposure which darkens
01:02the image a little bit.
01:06The opposite is also true. If we slow down the shutter speed, then that allows more light
01:11to hit the sensor and increases our exposure, but it also adds more motion blur, kind of
01:15makes things all creamy.
01:17Brian Liepe: So if you are going to adjust your shutter from the standard setting and
01:21crank it up, you're going to get a really crisp image like Chad said, and this may be
01:26appropriate for scenes that have a lot of action, or it's a highly dramatic scene, or
01:31sports; it's just going to give that edge to it and boost the intensity.
01:35Now a way to amplify this effect is to shoot this handheld, the foreground elements, the
01:41background elements, the subject, they are all going to kind of come together with this edgy look.
01:45If you put the camera on a tripod and you boost your shutter speed, yeah, it will still
01:50be crisp when the subject is moving, but the effect just won't quite be there.
01:56Now if you open up your shutter and slow it down a little bit, that can also create some cool effects.
02:01It's going to be wispy and there is going to be more blur, but you can affect your
02:05footage this way and create a certain style.
02:08Chad Perkins: Now sometimes this really isn't that big of a deal. Recently, I went out with
02:11my family to the zoo, we got some footage at the zoo, and I was--I had my aperture
02:16exactly where I wanted it. I had my ISO exactly where I wanted it, and I was just getting animals
02:21that were very lazy, that were not moving very much, and so my shutter speed really didn't
02:26matter. I could really make dramatic changes to my shutter speed and it really didn't make
02:30that big of a difference.
02:31Brian Liepe: Now it's not the best way to adjust exposure, but if you're going for a
02:37different look with your motion blur, then it might work for you.

Understanding ISO
00:00Brian Liepe: ISO is a numerical scale that refers to the sensitivity of a camera's sensor to light.
00:06Now ISO is based on something called the exposure index, which rates film stocks using a numerical value.
00:13As you lower the ISO setting, the sensor becomes less sensitive to light.
00:18As you raise the ISO setting, it becomes more sensitive.
00:21Chad Perkins: Personally I get a little scared adjusting ISO anymore than just a few increments.
00:26When you increase the camera's sensor sensitivity to light by bumping up the ISO, it adds noise,
00:35which can be awful.
00:36So in the next movie we'll look a little bit more about how ISO relates to noise and also
00:41to the colors of your image.
Collapse this transcript
Trade-offs with ISO adjustment
00:00Chad Perkins: In my mind, adjusting the ISO is just a really dangerous thing to do, or
00:04at least increasing the ISO is, and the reason why is because as you increase the ISO, you're
00:10making the sensor more sensitive to light which sounds good and it has its benefits,
00:15but also creates a much more noisy image.
00:18Brian Liepe: DSLR noise is super ugly. It moves poorly. It's got wonky colors. It's not
00:25monochromatic and it's just best to avoid it if at all possible.
00:31And later on in this training we'll look at some ways that you can decrease the amount
00:36of noise in your footage through some post-effects.
00:40But again, let's just try to avoid it when we're shooting.
00:42Chad Perkins: Now another thing that happens when you raise the ISO is that the colors
00:47become less saturated and just off a little bit.
00:49And because of the extreme compression that DSLR files go through, there is really not
00:55that much you can do about it in post.
00:57Brian Liepe: So if you are pressed for light in a certain situation and you do crank up
01:01your ISO, but it doesn't look like it has affected your image much because the monitor
01:06you're using doesn't show it, or your LCD screen doesn't show it because it's too small, just
01:11know that in post, when you look at that footage at its full resolution, you're going to see some ugly noise.
01:17Later in this training we're going to look at something called native ISO, and that's
01:21an ISO setting that works best for that specific camera and creates the best quality image
01:27with the least amount of noise.
01:29So yeah, remember when your boost ISO you're going to get noise, but it could help you
01:34out in low light situations.

2. DSLR Basics
Understanding sensor size
00:00Brian Liepe: One of the reasons these DSLRs have been such a huge hit is because of the
00:04size of their sensor. They are really big.
00:06This adds all sorts of benefits and one of them being its sensitivity to light.
00:11You can shoot in really low light situations.
00:13Chad Perkins: Right, but another aspect of the big sensors that these DSLRs have, is
00:19the very shallow depth of field, and I mean really shallow depth of field.
00:25Now a lot times this creates beautiful images, but sometimes this could be a real challenge
00:30when you want to get everything in focus, especially when you're shooting in really
00:35bright conditions.
00:36Now later on in this training series we'll look at some ways to manage excessive light,
00:41like when you're shooting outdoors, but this is definitely something to consider.
00:44Brian Liepe: The size of the sensor also affects the area which the lens can see.
00:48So in the Canon 5D we can see a lot more with the same lens then we can on the 7D because
00:54it has a smaller sensor.
00:56Chad Perkins: So it's almost like the Canon 5D makes all of your lenses wider because
01:01of a larger sensor?
01:02Brian Liepe: Exactly! This also means that with a 5D, we can achieve a much more shallow
01:07depth of field than we can with a 7D.
01:09So just beware that with these sensor sizes, as big as they are on these DSLRs, some of
01:14them bigger than 35mm film that they can be a blessing and a curse.

Protecting highlights and native ISO
00:00Chad Perkins: For most cameras there is a sweet spot when it comes to ISO.
00:05Basically what that means is there is ISO settings that just get better results.
00:08This is referred to as the native ISO.
00:11Brian Liepe: So for Canon cameras these are multiples of 160.
00:16So 160, 320 and so on, which means you'll probably get less noise at an ISO setting
00:23of 320 then you will at 200.
00:25Chad Perkins: One thing to be aware of, at least on these Canon cameras at least, is
00:30that for some crazy reason native ISO values conflict with something called Highlight Tone Priority mode.
00:39I love Highlight Tone Priority mode. It's basically a way that we can manage highlights
00:44and make them look better with these DSLR cameras.
00:46And we'll get into that a little bit more when we talk about the limited latitude of
00:50these DSLRs, but this is a real annoyance because if we want to turn Highlight Tone
00:55Priority mode on, it again disables those ISO values.
01:00Now a lot of professionals recommend that you actually do that, that you turn off Highlight
01:06Priority Mode so that you have access to all those native ISO settings. I disagree.
01:11From my experience, it's way easier to get rid of a little extra noise than it is to
01:16recover damaged highlights.
01:17But the choice is yours whether you want to have a little extra noise or damaged highlights.

Getting a custom white balance
00:00Brian Liepe: Sometimes these cameras have a hard time figuring out what pure white is.
00:04Sometimes there is a green tint or a magenta tint, or sometimes it's too warm or too cool,
00:09and the white just isn't quite there.
00:11Well white balance refers to the process by which the camera interprets pure white.
00:17Now once white is determined, these cameras are built to then represent all colors accurately.
00:23Chad Perkins: On most cameras you'll find presets for white balance, for a variety of
00:28common conditions.
00:29You'll have Tungsten for standard warm indoor lighting, or you might have daylight for a
00:36coolish outdoor lighting, but to really get the best white balance for your particular
00:42shot, you'll want to do a custom white balance.
00:46Brian Liepe: So here is how you're going to get a custom white balance in your camera.
00:51First determine which source of light is dominant, whether it's coming through a window, or it's
00:56incandescent lamps inside a room, and place your gray card underneath or in that light.
01:02Make sure it's in the center of the frame so the sensor can find it and snap a photo.
01:08Once you do that, navigate to the Custom White Balance option and choose the reference image you just took.
01:15Hit OK and your camera will calibrate itself. It's pretty cool.
01:19Chad Perkins: My background is in post production, so I'm frequently guilty of saying
01:24that really annoying thing when we're on set, like "oh just fix it in post."
01:28But white balance is not one of those things that you should wait to fix in post, and that's
01:33because the compression on DSLR cameras is so bad that there really isn't much room to
01:38play with it much in post. You've got to do this on set.
01:42Brian Liepe: Throughout shoots, your lighting conditions are most likely going to change,
01:47whether you change the lighting conditions yourself for a different scene, or you move locations.
01:52So go ahead and just get another custom white balance with your gray card.
01:56Now there is an auto white balance feature on these cameras and it actually interprets
02:02white as you're shooting, and you can actually see the color shift as different light sources
02:09become dominant in your shot.
02:11This is a terrible idea.
02:12I recommend always setting your custom white balance.
02:17So just to reiterate, for the best possible colors, grab one of these please and get custom
02:25white balance off of this gray card.

Focusing for video
00:00Chad Perkins: Focusing on a subject, especially when you're using a DSLR with a large sensor
00:04size and often has a shallow depth field, is extremely important regardless of what you're shooting.
00:11Brian Liepe: To get focus on your DSLR, in movie mode move the white focus rectangle
00:16to the area in the image you want to be in focus.
00:19Press the magnify button once for 5 times magnification or twice for 10 times the magnification.
00:25Spin the focus ring until you've achieved focus.
00:29Press the magnify button once more and it will toggle back out to your original frame.
00:33Chad Perkins: Most still photographers just can't live without auto-focus, but as videographers
00:40using our DSLRs, we don't have that luxury. We have to pull focus with the focus ring on the lens.
00:47But because of that, we could actually use old school SLR lenses, like this one here
00:52this old Nikon lens that I have, and you can often find really high-quality lenses for
00:57cheap, because you don't need them to have auto-focus they just have manual focus.
01:01So again, they are usually pretty inexpensive when bought used.
01:05Brian Liepe: In addition to the magnify feature, there are a few things that will help you maintain focus.
01:09Later on in this series we'll talk about a monitor and how it can help you achieve focus,
01:15and this contraption right here, it's called a follow focus.
01:19It will help you maintain focus on a moving subject.
01:22So remember these tools when you're trying to achieve sharp focus.

3. Understanding Lenses
Using lenses
00:00Brian Liepe: For those of you transitioning from traditional camcorders like this one,
00:04these DSLRs have one really big advantage that I think you'll like, and that's the ability
00:09to use different lenses or interchangeable lenses. Boom!
00:13Chad Perkins: Being able to switch lenses is a huge game changer, especially if
00:19you are a filmmaker, it just gives you so much more control over how you tell your story.
00:24Brian Liepe: So the quality of your image is largely determined by the quality of your lens.
00:30Now if you have a traditional camcorder and you're limited or you feel limited by the
00:36amount you can zoom, or its sharpness in some areas, or its fastest aperture, you got to
00:42go out and by a new camera.
00:44With these DSLRs, you can just go out and get a nice new lens.
00:48Chad Perkins: Now of course the downside of all of this is that these lenses can get really
00:53pricey. I have several lenses including this monster here that cost more than my entire
00:59camera just by itself.
01:01But as we go throughout this chapter and as we learn more about these lenses and what
01:05they can do, you'll see why these things justify those big price tags.
01:10Brian Liepe: Lenses come in a vast variety of focal length.
01:13The focal length is just the measurement of magnification expressed in millimeters.
01:17So the higher the number of millimeters, the more magnified the image is.
01:22There are two types of lenses; there is the prime lens and the zoom lens.
01:26With the zoom lens you can vary the focal length.
01:29In the prime lens the focal length is fixed.
01:32You're probably wondering, why would you ever put a prime lens on a camera? You can't change
01:37the focal length. Well there are a few advantages and to name some: they're sharper, they're
01:43faster, which means you can open up the aperture more, they represent colors and contours better
01:49and there is lens vignetting.

Understanding wide lenses
00:00Chad Perkins: Lenses are essentially grouped into two basic categories: wide and long, or
00:07in other words, telephoto.
00:08Brian Liepe: Normal lenses have a focal length of about 35 mm to 50 mm.
00:14Now the term normal just means it has a field of view that is closest to the way we see, with our eyes.
00:21Now the field of view is just how much of your scene is visible to the lens.
00:27Now anything lower than a 30 mm is a wide lens.
00:32Wide angle lenses are great for big landscapes or sweeping vistas. They are also really great
00:38about providing you with a great depth of field or everything in focus.
00:43Chad Perkins: I also tend to use wide-angle lenses when I want a subject to be particularly
00:48comedic, or scary, or otherwise just look ridiculous, because as you get a subject closer
00:55to the lens, when you're using a wide angle lens.
00:58Then things tend to distort, which can be really cool and a great effect if that's what you're are going
01:04for, but if you're trying to make someone look good be really careful with this effect,
01:11because facial features and other things tend to get distorted as you get closer to the lens.
01:16See right here that's, that's not good. That's not good.
01:19So avoid that at all cost if you are trying it again makes somebody look good.
01:23Brian Liepe: Exactly! Wide angle lenses also have a tendency to exaggerate the distance between objects.
01:30So if you are shooting a horror film and someone's running from the villain, you can exaggerate
01:36the movements of the villain and his speed with the wide-angle lens.
01:39Chad Perkins: I also like to use wide angles when I'm using cameras with a crop sensor
01:44like this Canon 7D here.
01:47The crop factor on these lenses are 1 and a 1/2 times what they would on a camera with
01:52a full frame sensor, like the Canon 5D.
01:55So a 50 mm lens on a Canon 7D would have about the same field of view as a 75 mm lens on a Canon 5D.
02:05Brian Liepe: One thing to keep in mind when you're shooting with the wide angle lens,
02:09is something called lens distortion. This occurs in corners of the frame, where a
02:15line that's meant to be straight actually takes on circular characteristics; it's a little bit curved.
02:20It could create a cool effect, but usually it's undesirable, especially when you're using
02:25a lot of compositing or visual effects.
02:27Note that this is less of an issue in higher end glass like the Canon L-series or this
02:32Zeiss ZE18 mm.
02:34Next, we're going to look at the other side of the coin, long or telephoto lenses.

Understanding long lenses
00:00Brian Liepe: We've looked at wide-angle lenses, which have focal lengths up to 30 mm to 35 mm.
00:06Now we're going to at the long lens or the telephoto lenses that have focal lengths from
00:11about 50 mm and up.
00:13Chad Perkins: Just as wide angle lenses zoom out so you could see more of what's going on,
00:20telephoto lenses, often referred to as long lenses, zoom in so you can get closer.
00:25And also in the same way that wide-angle lenses tend to expand subjects, so it expands the distance between objects,
00:35telephoto lenses, or long lenses, tend to compress the distance between subject and foreground
00:40and other objects in your scene.
00:42Brian Liepe: So again, going back to the horror movie example.
00:46If you are shooting a character running from danger, you could use a long lens which again
00:50compresses space. This would make the character seem to run without traveling much distance
00:56which can increase the tension.
00:57Chad Perkins: So let's say you're shooting a subject against a background in the distance.
01:03If you wanted to bring this subject and background closer together without actually moving anything,
01:08you could just use a longer lens.
01:11If you want the distance to between the objects to remain the same, but you wanted to be
01:16closer to the subject, you would want to actually physically move closer to the subject.
01:23Or if you want to make it seem as if the talent was closer to danger than they are, a long lens
01:27might be a good choice there as well.
01:31Another benefit of using a long lens is that you generally get a better shallow depth of field effect.
01:36If for example you want to create some beautiful Bokeh, which is what we refer to the out of
01:41focus areas of the image.
01:44Then you probably want to use a longer lens for that.
01:48Wider lenses have a really tough time getting beautiful bokeh regardless of whatever
01:52camera settings you're using.
01:53Brian Liepe: One last word of warning when using a telephoto lens;
01:57the longer the focal length the more sensitive to movement the lens becomes.
02:02So if you're dialed in on a long focal length and you're moving a little bit, you may not
02:06feel it that much, the lens is really going to see that shakiness.
02:10Here's a hand-held shot with a wide-angle lens. The shake is noticeable but it doesn't
02:15ruin the shot. Here's the same exact shot with a really long lens.
02:19And the shake makes the shot unusable as it is.
02:24The use of different lenses provides so many creative options, not only for magnification,
02:30but for storytelling as well.

Getting shallow depth of field
00:00Chad Perkins: So we've been talking here and there throughout this training series about
00:04getting that coveted shallow depth of field look.
00:07We thought it might be nice to just kind of combine all those tips and tricks and add
00:11little bit more to the story in this tutorial about getting a shallow depth of field.
00:16Brian Liepe: One of the first steps in achieving that really cool shallow depth of field look
00:21is choosing the right lens.
00:22I like to use a lens that has a focal length of 50mm or higher.
00:27Now it not impossible to get a shallow depth of field with a focal length less then that
00:32and we'll definitely teach you more about that later on.
00:35It's just easier using a telephoto lens because it magnifies those out of focus areas, and
00:40it just makes getting this look a lot easier.
00:42Chad Perkins: The next step in achieving shallow depth of field, is we want to of course open up the aperture
00:47as much as possible, because again, as we open up the aperture we're going to shrink that
00:52area of focus, and that's what creates that cool shallow depth of field effect.
00:57But again, remember also that as the aperture is wide open, at that stop and then next stop
01:02down, it's going to be a little softer then the other stops.
01:06Now that maybe okay in some instances, that might be a tradeoff, but just again be aware
01:11that that's going to happen.
01:12Brian Liepe: One of the final steps in achieving shallow depth of field is to make sure that
01:17the objects in your frame vary in distance in relation to the camera and each other.
01:22Even on an iPhone, I can take a photo of an object close to the lens, focus on it and
01:27my background will go out of focus giving me shallow depth of field.
01:31That's because the subject I'm focusing in is far away from the background.
01:35Now if I have a lot of objects in my frame that share the same focal plane, it's going
01:40to be hard to tell if I have shallow depth of field.
01:44So go ahead and breakup your objects,
01:47maybe by placing something in the foreground. Chad go ahead and raise that, that tripod up.
01:51I think it just makes things more interesting when you can break them up using shallow depth of field.
01:55Chad Perkins: Now one final tip is that highlights look absolutely beautiful when they are out of focus.
02:05Now of course you have to be tactful and use discretion with this trick, you don't want
02:10to over kill this thing.
02:12But being able to create that shallow depth of field especially with the beautiful highlights
02:17is an amazing effect that we strongly encourage you to master.

Using graphs to gauge exposure
00:00Chad Perkins: Some DSLR cameras, such as the Canon 5D and a Panasonic GH2, have an on screen
00:06histogram which can really help you gauge the exposure of your shot.
00:10To enable this on the Canon 5D, go to the back of the camera and click on the Info button
00:14a few times to cycle through the info modes, and eventually you will get to the mode with the histogram.
00:20This histogram is a read out of the luminance or brightness levels in your shot.
00:25From left to right we have shadows, mid tones and highlights.
00:30The height of the graph in these areas shows you how much of that particular luminance range you have.
00:37So this histogram suggests that our shot might be a bit too dark--certainly got a lot of
00:41shadows and not much in the way of highlights.
00:45This shot on the other hand suggests the opposite; lot of bright areas and not much shadow detail.
00:50Using a histogram could help you make sure that your image is balanced and could help
00:54you prevent blowing out highlights or crushing shadows.
00:59If your DSLR doesn't have a histogram, that's ok, it will still have a light meter called a spot meter.
01:07Now these light meters aren't as good and incident meters, which are actually physical
01:12things that you hold, and they actually get a reading of how the light falls in an exact spot,
01:18but the light meter in your camera is just good for getting an overall sense of the light in your shot.
01:24One final tip here, some people like to under expose by just a little bit--I'm actually one of those people,
01:31because I can then brighten things up back in post. I usually go one, maybe two tiny
01:37little notches down on the exposure meter on the camera. If you go any more that, you
01:41are going to get noise. It's going to be ugly.
01:44But having that image a little bit darker is just better then making things too bright.
01:50Whether you use a histogram, the camera spot meter or a physical incident light meter to
01:55gauge exposure, I highly recommend getting a reading before every shot.

Recording audio
00:00Brian Liepe: There definitely are some challenges when recording audio with a DSLR.
00:05Many of the cameras don't have any manual audio recording features. They use something
00:08called AGC, Automatic Gain Control.
00:12Which automatically adjusts the volume at which audio is recorded as it's being acquired.
00:18This can create some undesirable results.
00:22The automatic level adjustment just isn't fast enough to anticipate rapid changes in volume.
00:29There are three ways to avoid AGC: one, buy a camera with manual audio controls, like
00:35the Canon 5D Mark II and III or the Nikon D800.
00:40Two, record to an external audio recorder like the Zoom H4n.
00:45To do this, plug a shotgun mic directly into the Zoom,
00:55set your levels, and record high quality audio to an SD card.
01:07If your camera has an option for manual audio recording, switch it to automatic, so that
01:12your camera records a reference track.
01:15Before each shot, press the Record button on the Zoom H4n or an audio recorder, using this
01:21method you could then sync audio later and post using an application like PluralEyes.
01:27Three, if your DSLR has manual audio recording features, you can record to both your DSLR
01:34and external audio recorder simultaneously.
01:37This is definitely what I recommend. Using a mixer, you can go from your mic into a mixer,
01:45then from the mixer you can send two output signals; one to the audio recorder and the
01:51other to the DSLR.
01:53This will really help you sync up the audio in post, because the reference track from
01:57your DSLR will be very high-quality.
02:00Now remember most low end audio recorders can only take a mic level input same with
02:06the DSLRs, so when you're sending an output signal from your mixer you need a LINE level
02:12to MIC level pad converter like this one here.
02:16To send a line to your DSLR you'll need a female XLR to 1/8 jack adapter.
02:26Once you've done this, send a 1 kHz tone to both the recorder and the DSLR, set your levels
02:32to approximately -20 DB on both devices and you're ready to rock. This is how we're recording
02:39the audio for this tutorial right now.

Using a clapperboard
00:00Brian Liepe: Traditional film cameras don't have the ability to record audio, so they've
00:03had to record audio with an external recorder and then sync them up in post production.
00:08Because external audio recorders are also common with DSLR cameras, we have to sync
00:12up the audio and video in post as well.
00:16One of the most common tools for syncing audio and video is the use of a clapper board, also
00:20called a clapper or slate in production.
00:23It is common on sets to use a clapper board app for the iPad or other tablet.
00:29You can input info about the production and the shot, and then have it click like this.
00:38This gives you a visual reference, so that you can sync the audio and video later.
00:43In a pinch, you can just have someone that clap their hands in front of the camera.
00:48The key is to just do something that makes a distinct noise that you can see on camera.
00:53One last tip: set your date and time in your camera to match the clock on your slate.
01:02Although these cameras don't generate time code you can set the clock in your camera
01:06to your slate app so that in post you can see which clips correspond with the clock
01:11on your slate.

Shooting a "flat" image
00:00Chad Perkins: The default setting when shooting with DSLRs creates a high contrast, but beautiful
00:05image and that might be great for you.
00:07But the down side of that is it doesn't leave you much if any room to make changes later in post.
00:14Because of this I personally prefer to shoot flat.
00:18In other words, I actually want an image that is as washed out as possible. I don't want
00:22bright highlights or dark shadows.
00:24This ensures that I have as much detail as possible in both the shadows and the highlights.
00:29If you ever seen dailies from film shoots, you seen a very washed out image there too.
00:34It's just generally a good idea to get as much information captured as possible, and
00:39shooting flat is one of the best ways you can do that.
00:44Next, Brian is going to show you how to actually shoot flat, how to do it, and how to customize
00:49the look of the footage you capture.

Using custom color profiles
00:00Brian Liepe: One way to assign your own color and contrast characteristics to your image
00:04is by setting up your color profiles.
00:07Although I recommend shooting with a flat color profile like the one Chad discussed
00:12in the previous movie.
00:13There is a large range of options that allow you to affect your footage by adjusting controls,
00:18like saturation, contrast, sharpness, and color phase.
00:22In this example, you can see that color is not very vibrant or saturated and the contrast is really low.
00:28In the next shot I've cranked up everything. The colors are outrageous and the contrast is really steep.
00:34You can also see that I've lost some of my dynamic range.
00:37Remember when you increase the contrast you compromise the camera's ability to maintain
00:42information in the shadows and the highlights.
00:45You can also find online color profiles that other people have made that help you achieve
00:50certain looks and styles, such as those that resemble film.

Shooting slow motion
00:00Chad Perkins: Few things in life are more beautiful than a nice slow motion shot.
00:06Slow motion really just helps accentuate an action, calling attention to it and demanding
00:11an audience's focus.
00:14Most DSLRs have the capability of shooting slow motion, depending on the frame rate you are using,
00:18so assuming that your project is a 24 frames per second project, even shooting 30 frames
00:25per second creates a 25% slower product.
00:29Many DSLRs go up to 60 frames per second which creates at least a 50% slower video if your
00:34project is either 24 or 30 frames per second.
00:38Remember that if you change your frame rate to 60 frames per second you also need to increase
00:43the speed of your shutter to 1/125th of a second which will probably lower your exposure, so plan for that.
00:50Beware also that in order crank up the frame rate to 60 frames per second, many of these DSLRs
00:55force you to lower the resolution.
00:58This will create a mismatch between the other footage that you've shot.
01:02So you will then have to either scale up the slow motion footage to match everything else, which
01:07actually is a terrible idea, or more than likely you will have to scale everything else down.
01:13So slow motion footage is incredible but there definitely is a price to pay for it.

Getting a beautiful shot
00:00Chad Perkins: In this video we're going to do something kind of unique and pretty awesome.
00:05What we're going to do is we're going to take a regular old ugly shot like this,
00:10and we are going to show you some real-world easy things to do to make it absolutely beautiful.
00:16Before we get started, let's introduce our beautiful model Kelsey.
00:20And Kelsey Tiger is a good friend of ours and she's worked with me on this iPad app
00:25that I did. She played the lead,
00:27and she's also on the cover of one of my books.
00:29And she's just an amazing model to work with.
00:31Brian Liepe: We started out with the subject against a wall, no lights and a 24 mm lens
00:37which shows some distortion in our subject's face.
00:40So we moved her away from the wall, moved the camera back, and threw on a 35mm lens.
00:48This gave us more depth and lessened the distortion in her face.
00:53We then turned off the practical lights, which are just the light fixtures that are built
00:57in to the building, because they just looked awful.
01:01We lit her using two soft LED lamps jelled with Lee 216 filters, and then we shot the
01:08lamps through a silk for extra softness.
01:12We added a light behind her jelled with a diffusion material called opal, that gilded
01:17her hair and her shoulders.
01:20Chad Perkins: So the lighting is beautiful, but there is more to a beautiful shot than
01:26just the lighting.
01:28We have to worry about something called production design.
01:31Production design is basically what the set looks like, what the environment looks like.
01:35So what we decided to do is get our model all dolled up, we got her with beautiful hair,
01:40makeup, we changed her clothes. We just got her looking great.
01:45And then we also look at our background. The background just is plain old black so let's
01:48add some lights to it. Let's put some beautiful little lights in the scene and that definitely
01:53improved the quality of our shot.
01:55Brian Liepe: After all of that, we thought, we want our out of focus area to pop a little bit more.
02:01So we backed the camera up, brought the subject even further away from the background and
02:05threw on a telephoto lens.
02:09We then opened up the aperture even more, so could get those highlights to pop.
02:13Chad Perkins: Another really important concept when getting a great shot is that you want
02:19to worry about the foreground, the middle ground, and the background.
02:23Well we already have the cool lights in the background. We also have the talent in the middle area.
02:28We don't really have anything in the foreground.
02:31So we thought we'd add just a little bit of stuff right here in the foreground
02:35and it'll go out of focus and look all pretty like that.
02:38And now we have this great sense of depth in our shot; something in front, in the
02:42middle, and in the back.
02:44Brian Liepe: So we use those layers and thought okay, let's make this even more cool and add
02:50a slight camera move.
02:52You can see the foreground elements move and it really accentuates the depth that we made
02:57by backing up the camera, and putting the subject further away from the background, and then
03:02adding this foreground element.
03:03And we just moved camera slightly.
03:06Then we added some blocking for our model, and voila, we got a pretty shot.
03:12We did things in this order so that our changes were obvious. In a professional environment
03:18getting the shot is influenced heavily by the amount of time it takes to set up.
03:24So usually it's more efficient to first set up framing, then light, and your team will have
03:29already taken care of things like wardrobe and production design.

5. Postproduction
Why use Premiere Pro for editing?
00:00Chad Perkins: In this chapter, we are going to head to the computer and look at DSLR video
00:03files in postproduction.
00:05Throughout this chapter, I am going to be using Adobe Premiere Pro which is my video
00:09editor of choice.
00:11The reason why it is, because this codec is very tough for video editing systems to use.
00:19It's often very slow and so the footage often has to be transcoded or re-encoded to a different
00:25format in order to be usable.
00:27But with Premiere, I can just drag and drop and use these files in my timeline.
00:33As you can see, Premiere handles these files like a champ.
00:36This is RAW H.264 files straight from the camera.
00:39And as a matter of fact, I actually used Adobe Premiere Pro to edit this entire course and
00:46add the b-roll and everything that I had to do with this course and everything.
00:50As you could tell, it's kind of a mess, editing this footage together.
00:54But Adobe Premiere Pro at least handled it really well.
00:58Brian and I, not so much. We didn't do so great, but Premiere was a champ handling these DSLR files.
01:05And while there are many great video editing solutions to use, again I prefer to use Premiere.
01:11Regardless of which software application you use to edit your video footage, the concepts
01:16that we talk about in this chapter will be universally applicable.
01:19So don't worry if you don't use Premiere.

Transcoding video
00:00Chad Perkins: As I mentioned in the last movie, I prefer to use Premiere because I can just
00:03bring in H.264 files and just get to editing them.
00:08But you may prefer a different editing system or you may prefer to transcode your files
00:13anyway, so that they run smoother even in Premiere.
00:17If you're using Adobe products, you might want to use the Adobe Media Encoder. And you
00:21can just drag and drop files from your computer's operating system, either Explorer or the Finder
00:26on the Mac, just drag them here and then you could change the format through this drop down
00:31and you could change or use a series of presets.
00:35You could also change where you are going to save it, and whenever you're ready you
00:38just click the Play button.
00:39And whatever files you have loaded here into this window, will render one after another.
00:44Now as I mentioned, the H.264 files that most DSLRs create are really tough on editing systems.
00:52Even with Premiere, if you start adding a bunch of effects, it's going to start slowing things down.
00:56So usually, if you are going to re-encode the footage, you want to use the most efficient
01:00editing codec possible.
01:02Perhaps the most popular format for transcoding is a QuickTime file that uses the ProRes series of codecs.
01:13These are really high-quality files that are just really easy for editing systems to use.
01:18Now in order to use the ProRes codec when encoding footage, you will need to have either
01:23Final Cut Pro or Compressor installed on your system.
01:28If you don't have those installed, you can go over to the Apple App store on a Mac, if
01:33you're a Mac, and get Compressor which will install not only the software compressor which
01:38is kind of like Adobe Media encoder, but just different; it's Apple's version of kind of
01:43like Adobe Media encoder, re-encoding software.
01:45But it also will install the ProRes codecs.
01:50Now if those aren't options for you or if you're on a PC, I might recommend going to
01:54cineform.com and getting something called NeoScene.
01:58This will allow you to encode AVI files that are CineForm AVI files.
02:04So it's kind of like the best possible equivalent on a PC of Apple's ProRes.
02:10Now again, it's not always necessary to transcode and it does take a long time for the workflow,
02:15but then when you're editing, it's just so much smoother.
02:19So it's your choice whether to use an editing suite like Premiere where you could just dump
02:23the files and start going, or if you would like to transcode to get things moving a little faster.

Combining video and audio streams
00:00Chad Perkins: As Brian mentioned earlier in this training series, the best possible way
00:04to get good quality audio is to record through a separate audio stream, and because of that,
00:12those video and audio streams have to be re- synced together in post, which if you have ever done
00:18that before, it's just a nightmare. It's so tedious and it takes so long, and it's almost
00:23impossible to get exactly right.
00:25Well, there is this great tool called PluralEyes from Red Giant software and this is just an amazing product.
00:34Here's how this works.
00:36In PluralEyes, I can select Camera and then I import all of my video footage.
00:42Now this video footage needs to have kind of like a scratch audio track, just basically
00:46using the camera's really terrible microphone built-in is totally fine.
00:53Once we have imported our video, we click on the Audio Recorder and bring in the high-quality
00:58audio, which we can do by clicking this little plus icon by the way.
01:02So now I have in here a load of video and a load of audio and how they match up, I don't
01:09know, we were not doing a very good job of slating, or in another words using a clapper
01:14board, and it was just totally a mess.
01:18But it doesn't matter when you are using PluralEyes.
01:20All you have to do is import all the video and all the audio, you don't even have to
01:24connect the two together and all you have to do is just click the Synchronize button
01:28and like magic, PluralEyes will find out which video clips correspond to which parts of the audio files.
01:35And it will make all new video files for you.
01:38You could also import timelines from Premiere or other video editors and you could also
01:45export the timeline with the new audio and video files.
01:49Now some video editing programs, like Final Cut Pro 10, have this similar functionality
01:55at least built-in.
01:57But really, this is the best way to do it and this is kind of like the industry standard
02:02when you are synching video and audio streams with DSLR footage.

Cleaning up noise and adding grain
00:00Chad Perkins: So as we have talked about before, noise is a terrible thing and you want to
00:04avoid it in your footage at all costs.
00:06But sometimes there's conditions where you might not have time to set up enough light
00:11or whatever else is going on, and you just end up with noise, and you've got to get rid of it.
00:15So there are a few tools that are brilliant and amazing that we can use as a last-ditch resort.
00:21So here is my footage with noise and I'm hoping that through the compressed footage that you're
00:27watching this on, that you can tell how badly this is just reeking of noise.
00:33So one of my favorite tools is the Denoiser II by Magic Bullet which is sold on redgiantsoftware.com.
00:41And all you have to do is drag and drop it, and you could see already, as I have been talking,
00:46it cleaned up everything and it's done.
00:48So as long as the resolution is full, and I am here in After Effects, but it also works
00:53in Premiere and other hosts, but all we have to do is just change my Resolution to Full
00:58and once it's applied, it automatically cleans up my footage.
01:01Now there is still noise there.
01:04As we render this, you'll see that it's impossible to completely clean up the footage without
01:08degrading the quality, but it does an amazing job.
01:12Now in most cases your noise will not be this bad, so when you apply Denoiser, it's going
01:17to be amazing and it's going to be perfect for you.
01:20So then what you will want to do at that point is actually add noise back in because sometimes
01:24these denoising applications can remove too much noise, making the footage look kind of
01:29sterile, and especially if you are trying to make something look filmic, film stuff has grain.
01:34So what I would like to do in After Effects is add grain with the Add Grain effect.
01:38This is much slower to render, but it's much more filmic grain.
01:42We could use a preset here, I don't know, Kodak Vision 500T for example.
01:48Really grainy, so I am going to take the Intensity down to 0.2.
01:52So it's very subtle here, but it does give some life to our footage and some texture.
01:56And I will change the viewing mode from Preview to Final Output.
02:01Now we have some nice filmic grain in our footage.
02:05It's not overbearing. It doesn't make it look gross, and especially when viewed at size,
02:10I will take off my region of interest here, it just makes everything look very authentic,
02:18very organic and real, the way film might.
02:21Here is that footage played back now, we rendered it and maybe that's a little noisy.
02:27So we could take this down a little bit more.
02:30But again, these settings usually work when you're adding back a little bit of noise or
02:34grain to a footage that has been cleaned up with noise.
02:37Now you might not have Denoiser II. There is an alternative.
02:41If you go to a neatvideo.com you can get Neat Video which is very similar. You can use it
02:48with Premiere. You could use it with After Effects. You could also use it with a host
02:52of other video applications here.
02:55And don't let the website, that looks like it was created in 1998 fool you. This plug-in
03:01is actually incredibly powerful and very amazing, and it also has sharpening built-in as well
03:09which is something that often needs--that you need to do after you clean up noise and grain.
03:14So again, I repeat that it's best to avoid noise when shooting as much as possible, but
03:19for those times when you do have a little bit of unexpected noise creep up and post,
03:23these are the best tools to get rid of that.

Color correcting footage
00:00Chad Perkins: In this tutorial, we are going to look a little bit at color correction.
00:03As I have mentioned several times before, I really like to shoot flat, in other words
00:07I don't want really dark shadows. I don't really want bright highlights. I want it look
00:12as washed out as possible, like this image here, and now I could show you a little bit
00:17more closely why I like that.
00:18I am going to apply the Levels effect, I am here in Adobe After Effects.
00:21Again, you don't have to be here, but this is a good way to kind of describe and show
00:26you what I'm talking about here.
00:28So I apply the Levels effect, and I have this histogram that gives me a readout of my shadows,
00:34midtones and highlights.
00:37As you can see here by the flat level, we really don't have too much shadow detail here,
00:43and we don't have much highlight detail. Everything is washed out, which again, is great.
00:48So I can drag this slider in, the Input White triangle and I could drag it until there is data here.
00:56Do the same thing with the shadows, drag the Input Black, until we reach some information there.
01:04And then I could adjust the Gamma slider, which adjusts the midtones, which I got to
01:08the right, make that a little bit darker.
01:11And now--actually maybe this is blown out a little bit next to his hair here.
01:17But now we have a good balance of color.
01:20We could play with the midtones a little bit, but the point is, is that we have room to
01:24play with the highlights here. We could see all the detail in the sky, and we could see
01:29all the details in the shadows in his shirt, so nothing is crushed or blown out.
01:34So even though these cameras have a really limited dynamic range, because we shot so
01:39flat, we have a lot of room to move this around before it starts looking ugly.
01:43Of course then we could apply may be a Curves effect and really get into a more detailed
01:50color correction where we maybe go to the Red channel and make this a little bit more
01:54warm, or we could maybe go to the Blue channel, make this a little bit more cool if we wanted
02:00to, or we could go back to the Red channel and suck some of the red out if we want this
02:05to be more like intense, like Hollywood action movie or something like that.
02:11But again, because we shot flat, we are going to have less problems.
02:15There is a little bit of a highlight here, again, it's driving me nuts, and so I might
02:19want to take down the Highlight Correction a little bit just to smooth that out, but
02:24again the point is, is that we have a lot of flexibility here because we shot so flat.
02:28Now let's look at another example here where I didn't shoot quite so flat.
02:32I didn't have all of the filters that Brian was talking about where I could get rid of some
02:37of that light, and it was like a really quick situation where we didn't have much time to
02:42shoot, so we just kind of, what they call, run -and-gun, where you are just going to grab
02:45the camera and go for it.
02:47So what's going on here is that if I reset my Histogram, we can see that the highlights
02:56here are already blown out. We already have pure white in our image and a lot of it.
03:02So we can move our shadow endpoint here, the Input Black slider in and that gives us back
03:07our shadow detail.
03:09And we could also darken the image using the Gamma slider and now it looks a lot better.
03:15So here is before and after.
03:17But the problem is, is that his red shirt is a little bit glowy. It's bouncing off the
03:23light in a weird way and it's the most eye-catching thing in the whole shot.
03:28And I can tone that down a little bit with the Output White slider as we talked about,
03:33but it really doesn't do too much good in this case.
03:36So we're stuck with a shot that probably could be better, but again we really don't have
03:41the flexibility because when this image was captured, there was just too much in the way
03:46of highlights, and so, we have this posterization here, this like hard edge where the highlights
03:53blow out and again we have this way too bright red here in his shirt and there's just not
04:00much we could do.
04:01So I hope that now that we have gone through some of these color tools a little bit more
04:04closely, that it's a little bit more clear why it's so important to me to shoot a flat, washed-out image.

6. Common DSLR Pitfalls
About DSLR pitfalls
00:00Chad Perkins: Hopefully, you have seen how great these DSLR cameras are.
00:04They are just so small and just adorable.
00:07And they are also ridiculously inexpensive.
00:10But there is a downside to all of this; these cameras were not created to be used for filming
00:16movies or in professional video production.
00:19And yet that's where the world has decided to use them.
00:22So before you jump into using these cameras, let's take this chapter and look at a few
00:26problems you are likely to encounter while working with them.
Collapse this transcript
Avoiding rolling shutter
00:00Chad Perkins: Many DSLR cameras have something called a CMOS sensor.
00:04The CMOS sensor looks at your image a line at a time, and it doesn't often read and record
00:09data fast enough to keep up quickly with moving objects, or when the camera moves around quickly.
00:16This creates what is referred to as a rolling shutter effect. It makes straight lines wavy
00:21and generally creates a wobbly look.
00:24Because of that, this is colloquially referred to as jello cam.
00:27While there's not much you can do to fix this completely, there is a fix in Adobe products,
00:32such as Adobe After Effects or Adobe Premiere Pro that can kind of reduce this effect and
00:37all you have to do is apply it to have that fix applied. It's incredible.
00:41In some cases, you can completely get rid of any rolling shutter problems with this
00:45amazing software, but it is best to avoid it in the first place if you can help it.

Avoiding moiré
00:00Chad Perkins: A common problem for many video cameras, including DSLRs, is that of moire.
00:05This is a really interesting, but also really ugly visual phenomenon that creates weird
00:11patterns and jagged lines like this.
00:14This problem, caused by the camera's sensor, is most obvious when filming things with fine details.
00:21Stripes on people's shirts are one of the most common causes of this, but anything from
00:25the pattern on a distant building to patterns in fabrics, can cause it as well.
00:30DSLRs just have a hard-time resolving these details.
00:34There are filters for your camera that you can purchase that reduce or even eliminate
00:37moire, such as the VAF-5D2 filter.
00:40We haven't tested them and they are kind of pricey, but that option is there. Let's be clear;
00:46moire is an abomination.
00:47And once your footage is captured with it, there's nothing you could do to fix it.
00:52So do whatever you got to do to avoid it.
00:54If you have to, talk to the producer or director about wardrobe choices and let them know of
00:59the potential problems.
01:00Moire is certainly something that should be given forethought and avoided at all costs.

About limited latitude
00:00Chad Perkins: One of the biggest problems that I have with these little DSLR cameras
00:05is they have such a limited latitude.
00:06It basically means that the camera has a hard time taking in and correctly registering bright
00:12areas and dark areas at the same time.
00:15One or both of these areas usually suffer.
00:19To make matters worse, when you do have something that is too bright or too dark, it just looks terrible.
00:24Typically, what you want, even in blown-out areas, is a nice subtle gradation from white to darker tones.
00:31But on DSLRs, when you blow out your highlights or also you shadows, you will get these lines
00:37where the tones instantly drop off.
00:39The camera just can't see anything in between this pure white and the slightly darker tones next to it.
00:46Because of that steep drop-off from blown out white to other tones, this problem could
00:51be next to impossible to fix in post-production.
00:54There is a little fix that might help.
00:56If you're using something like After Effects or Premiere or some other tool that has a
01:00Levels effect, you can go to the triangle on the far right side of the Histogram and
01:05then go to the triangle below that, it's called Output White triangle, drag that inwards to the left.
01:11This reduces the brightness of the brightest parts of the image.
01:14And if you're lucky, this trick might smooth out that hard edge, then you could go back
01:19and universally brighten all the pixels.
01:22If you're still getting blown out highlights or super dark shadows, then use some of the
01:26other methods we've been talking about for adjusting exposure throughout this course,
01:29so adjusting the aperture, shutter speed, ISO, or you can try to block, or diffuse the
01:35light, or you could use a neutral density filter, which Brian will be talking about in the next
01:38chapter, which basically is a dark piece of glass that you put in front of the lens to
01:43lower the exposure.
01:45But the limited latitude is something that it looks awful and amateurish when it
01:49shows up in footage.
01:50So make sure that you're doing everything you can do to preserve data in the highlights
01:55and shadows.

About extreme compression
00:00Chad Perkins: Another big problem with these DSLRs is how they compress the video files
00:05that they create.
00:06Initially, they were meant to be deliverable files.
00:09You would just record the videos and then post them online or turn them in to your boss or whatever.
00:14But with the proliferation of DSLRs, we often want to use them in post.
00:19But because they're already so heavily compressed, there is really not much room to play around
00:24with them when you're in post-production.
00:25For example, this heavy compression makes it really challenging if you're trying to
00:30remove green screen.
00:32While more pure footage removes green screen more cleanly and evenly, even the best green
00:39screen footage shot on a DSLR is still really compressed and creates artifacts that are
00:44just a beast to remove.
00:46And then when you want to composite that footage with other material, it's so compressed that
00:50you really can't adjust the colors very much without destroying the footage.
00:55That being said, it can be done.
00:56When the Canon 7D first came out, I shot a huge series of visual effects shot for an
01:01iPad app that I made before I realized how horrific the compression was.
01:05I made it work, but it was a chore.
01:08In some of these DSLRs, like the Panasonic GH2 for example, they have a mode that will
01:13allow you to choose an alternate means of compression such as Photo JPEG.
01:18This is definitely preferable to using the usual H.264 if it's at all possible.
01:24Again, as I pointed out, you can make these files do some work in post with light visual effects
01:29work, compositing, and so forth, but it can be difficult if not impossible to get these extremely
01:35compressed files to do what you want them to do.

7. Important Gear
Why you need a monitor
00:00Brian Liepe: There are so many advantages to using external monitors with your DSLR.
00:04Most DSLRs have a mini HDMI connection from which you can send an HD video signal to a
00:10third-party monitor.
00:11Typically, the screens are larger than the LCD on the back of your camera and with the
00:16proper hardware, we can reposition the screen to accommodate different shooting conditions.
00:21A lot of these monitors have a variety of tools that can help us with focusing and exposure.
00:27They can tell us where our highlights are not protected. They can enhance edges and
00:31pixels and lines and contours to help us achieve focus as well.
00:36One of the most valuable benefits to using a monitor is that the image can be more easily
00:41shared with your collaborators onset.
00:44Positioning the monitor or looping the signal through to additional monitors allows your
00:50team to see what's being captured by the camera.
00:53This helps with communication immensely, which is super important on set.
Collapse this transcript
Using a viewfinder
00:00Brian Liepe: Viewfinders, like monitors, help the camera operator in shooting conditions
00:04that require a close eye on the footage that's being captured.
00:08For example, in really sunny locations, trying to see the LCD screen is extremely difficult.
00:14Even with shade, light is coming in from every direction, from the sun, bouncing up
00:18from the ground, just making it really hard to see what's going on.
00:22So use a viewfinder which keeps the light from obscuring your view of the LCD and seals
00:27in light at the point of contact with your eye.
00:30I used a Zacuto Z-Finder for all these shots in Africa where the sunshine was way too bright
00:37to see my LCD if I didn't have it.
00:41The viewfinder typically magnifies the image anywhere from 1.5 times the actual size to
00:46three times the size, so that the image fills your field of vision when you're operating the camera.
00:52

Stabilizing your camera
00:00Brian Liepe: These DSLRs are really lightweight.
00:02When shooting handheld, it's very easy to simply hold the camera in your hands for an extended period of time.
00:08But there are some drawbacks to the size and weight of these cameras.
00:12If I'm shooting on a lens that doesn't have a stabilization mechanism or I'm shooting
00:16without stabilization hardware, like a shoulder mount, the longest focal length I can safely
00:22operate or operate without unwanted shake is about a 24 mm lens.
00:27Anything longer than that is when I start to see that my arms just aren't good enough
00:32and that that natural breathing life giving movement that we all love about handheld shooting
00:37transitions to a kind of unnatural and harsh camera shake.
00:41So in order to avoid this we need to weigh down the camera and mount it so that we can
00:47still have the freedom of those fluid drifting shots.
00:50One way to do this is to use a shoulder mount.
00:53Here you can see that I've got counterweights on the back, so the leverage point exists
00:58along the rails at my shoulder.
01:01So my hands are simply guiding the frame and I am not struggling to keep the camera up.
01:05I can easily adjust my focus and the grip handles for all that control that I need.
01:10As you can see here in this shot, I'm shooting with an 85 mm lens and no stabilization hardware, pretty bad.
01:17Here is the same shot, same lens, only with my shoulder mount giving me some weight and balance.
01:24I encourage you to take advantage of valuable storytelling techniques like handheld shooting.
01:30But remember to stabilize your camera as much as you can, whether it's on your shoulder,
01:35on a tripod or even a monopod, which by the way, can get your DSLR into some pretty cool positions.

Moving your camera
00:00Brian Liepe: Adding movement to your shots really enhances your ability to tell a story.
00:04Whether at shooting handheld, like we discussed in the last movie, or placing your camera on
00:09a jib, camera movement allows the audience to engage in a story in a very effective and unique way.
00:15Here is a small tool that can add a big cinematic effect to your shots, it's called a slider.
00:22Just adding a slight deliberate and slow movement to your shot can help reflect elements in
00:28your story, plus there is something sort of magical about giving the audience a perspective
00:33that moves through space.
Collapse this transcript
Using a follow focus
00:00Brian Liepe: A follow focus allows the operator or first assistant camera person to maintain
00:04focus on a moving subject without touching the lens directly, which can sometimes increase
00:09the risk of shaking the camera or lens.
00:12The lens must be wrapped with a gear which has teeth that are of a corresponding pitch.
00:17Now the pitch just refers to the distance between the peaks and the valleys on that gear.
00:22You can use a grease pencil or dry erase marker to indicate points on the marking disk that
00:27correspond with the actor's movements in the scene.
00:30This way you can follow the subject and pull the focus accordingly.
00:33They're pretty cool. I like them. I use them a lot.
Collapse this transcript
Using a matte box
00:00Brian Liepe: A matte box can be really useful if you're working with a lot of hard lighting.
00:04Hard lights that shine into your lens can cause lens flares.
00:08Although some shooters embrace flares, they can be undesirable if they show up in parts
00:12of the image that need to remain clean or unaffected.
00:16The matte box is built to accommodate a wide range of focal lengths.
00:20The size of its opening increases, so it doesn't show up in your image.
00:25The walls of the matte box block rays of light that would otherwise shine into the glass of
00:29your lens, which obviously is what produces lens flares.
00:34You could also use a matte box to hold filters.
00:37I use my matte box to hold high- quality neutral density filters.
00:42In a matte box like this, I can hold NDs in these frames, which allows me to switch lenses
00:47without having to unscrew filters from one lens and screw them back onto another.
00:52This saves me a lot of time.
00:55If you do use a matte box to hold your filters, make sure to seal off the back of the matte
00:59box with a donut.
01:02These prevent light from leaking and reflecting off your filters and then back into your lens.
Collapse this transcript
Using neutral density filters
00:00Brian Liepe: Neutral density filters, commonly referred to as NDs, are just another set of
00:05tools you can use to adjust your exposure.
00:08They are usually used when shooting outdoors.
00:10If it's just too bright to open up your aperture for shallow depth of field, place an ND filter
00:15in front of your lens either by threading one on or by using a matte box that can holds
00:20neutral density filters.
00:22Just as a side note, different lenses have different filter diameters or sizes, so you
00:27can buy a filter that matches your lens.
00:30Some lenses have a symbol called a ligature that indicates the diameter of your filter size.
00:37The density or the amount of light NDs filter out are usually fixed to one stop increments.
00:43So if you're shooting on set and you have too much light, you put an ND in front of
00:48your lens and it's not quite the amount of reduction you need, you've got to go grab
00:51another one or just adjust your camera settings, which you may not want to do.
00:56So if you're wasting time by swapping out different NDs, you can use something called
01:01a variable ND. These are so cool and super valuable.
01:06Variable NDs are great for DSLRs because they allow you to adjust your exposure without
01:11changing your aperture or your shutter speed or your ISO.
01:14You have the ability to change your exposure without fixed increments.
01:19You can just spin the ring and easily achieve the amount of exposure you need.
01:23You can see here that the exposure changes and nothing else does, my aperture, my shallow
01:28depth of field all remain the same by me just spinning that ring.

Conclusion
The future of DSLR video
00:00Brian Liepe: The technology that these cameras use isn't going anywhere and the future is
00:04probably just going to get better.
00:06Chad Perkins: For example, there is a new Blackmagic Cinema Camera that people are talking about.
00:10It's just like a DSLR, shoots 3K footage and it's raw. Just incredible!
00:16Brian Liepe: Yeah, and then there is the new GoPro Black that shoots 4k, 15 frames per
00:20second, but still that's a small camera that can shoot 4000 lines of resolution.
00:26There is also the RED SCARLET which has same form factor as a DSLR, but is way more powerful;
00:33different frame rates, different resolutions, different latitude and dynamic range.
00:37Chad Perkins: So as you could see, a lot of the information, probably most of the information
00:42we covered in this training series is kind of future proof. It's not going anywhere.
00:45These DSLRs and this idea, this revolution that so much power can be packed into little
00:50tiny camera, this stuff isn't going anywhere any time soon.
