In Premiere Pro CS4 Beyond the Basics, Adobe Certified Instructor Chad Perkins explains how to take video editing from simple nuts and bolts to an art form. He shares tips for shooting video in the field to get the most from a subject and get the best footage for a project. He demonstrates how to build a project through the careful use of cutaways, pacing, and suggestive edits. He covers special effects, color correction, and keying and compositing, integrating all these concepts as he builds a music video project from scratch. Exercise files are included with this course.
So let's face it. The world has pretty much gone HD and what segments of television have not gone HD will very soon. iTunes and Netflix and other companies that even distribute video over the Internet are even now streaming HD video. I actually have a Netflix video player that streams HD video. It looks phenomenal. So it's only a matter of time before everything is all HD, all the time.
So I want to just talk a little bit about some of the HD standards. When we're working in Standard Definition Video, it's pretty simple. After a while, they started coming around with wide screen and full screen but the pixel counts were the same. Although nothing has changed with the pixel aspect ratios, but now that HD has entered the mix, there is a whole slew of formats and sizes. Let's talk about those a little bit. Again as a teaching tool, I am going to go and create a brand new sequence, so we can look at these settings here. We know that we have standard DV. These are a Standard SD formats.
One of them that's not listed here is EDTV. We know that we have SDTV, Standard Definition. We have HDTV, High Definition. But there is also EDTV, which is Enhanced Definition TV. Essentially that's the standard NTSC pixel count with a 720x480. But it also has progressive frames and not interlaced frame so it's often seen as 480p. Now one other thing that's good to pay attention to are all these crazy numbers. It's that these are the number of vertical lines and so we have 480 vertical lines and so SD is now referred to as 480i and the "i" refers to interlaced frames, "p" refers to progressive frames. So 480i is SD.
480p is EDTV as mentioned. And I mentioned that because the Nintendo Wii is so popular. And moreover a people are creating games from scratch using Flash. My brother Todd has created Lynda titles on creating Wii games in Flash and creating videos and watching video on the Wii. It's good to know those frames rates. And actually not just the frame rates but the sizes and dimensions and all that kind of stuff. So then we move up to 720p. It's at 720 vertical lines and that resolution is 1280x720, and note that it has a square pixel aspect ratio.
Now while this is considered HD, true HD is actually 1920x1080. Now HDV as you can see here is 1440x1080. That's not what we are looking for and so we need to actually move up to an HD standard here, 1080p for example, and AVCHD is 1920x1080 with square pixel, so this is true HD. It should also be noted that 1080i is also considered HD but for the ultimate, ultimate HD experience, it's really 1080p. That's 1920x1080 pixels with progressive frames.
Because of the increase in quality when using progressive frames, a lot of people feel that 720p is about the same quality as 1080i even though there are fewer pixels. Personally I prefer 720p. It's nice and clean. I love working with progressive frames. The farther away we get from SD, the easier our lives as editors are. The more we can get rid of weird pixel aspect ratios and the more we can get rid of interlaced frames and all that junk, get it out of the way and the new HD progressive format, although it's a little more taxing because there is more pixels.
they take away a lot of those issues that we have to deal with SD. Now it's also point out here, as demonstrated by the AVCHD Presets, that there are different frame rates for HD. HD unlike SD allows 24 frames per second, 30 frames per second and 60 frames per second and for PAL it also allows for 25 frames per second and 50 frames per second. I should also point out that in some technical writings, frame rate is referred to as Hertz.
So as you see something like 720p 60 Hertz, what it's saying is it's 720p video. It's 60 frames per second. Now one final note as we are looking these presets here, I feel I probably should tell you that if we go over to the General tab and you go to the Editing mode, we can see that there are more editing modes here and other presets here that we don't see in the Sequence Preset say, for example RED Cinema here which I don't believe is in the available presets area, no. It's not. So we can have RED Cinema, which is getting wildly popular, and we will see much more of in the future to be sure.
And it also pays to note that because of the RED Camera, which is increasing in popularity, and the RED Camera allows you to go a bigger than HD. It allows film sizes of 2K and 4K which is basically the 2000 pixels and 4000 pixels respectively. And also because RED is introducing the new sensor that they're coming out with that goes up to like 20 something K. So 20 something thousand pixels for their epic cameras, and so that's going to be a big deal. It's no wonder that Adobe has already announced that CS5 will be 64-bit native, so you will have more RAM to be able to process all of these huge frames that are coming out.
But as far as HD video goes, those are the standards. Who knows what the future holds as far as 2K and 4K and whatever else beyond that? But as for right now, those are the standards for HD.
