Join Nick Harauz for an in-depth discussion in this video Options for Blur, part of Sapphire for Video Editors.
- [Instructor] In this movie, we're here to talk about some of the blur options that are available from Sapphire. A great way to find that is if you go to your Effects tab here, I'm in my Effects workspace, and I'm in my Chapter 4_1 sequence. Scroll to Video Effects, and from there, I'm going to go into my Sapphire Blur + Sharpen category. I'm going to just select S_Blur to begin, because this is a pretty powerful effect. Once I apply that to the clip, you can see that it's gone blurry. Now I'm just going to press Shift + 5. Like all effects, you can always start with a preset.
What's really cool about this type of blur from Sapphire is that there is some color correction as well as glow that is mixed into it to create some really interesting effects, as well as you have control over both the X and Y glow to create vertical glow, let's say, on a particular axis or a horizontal glow on another axis. Whatever it is, you can pick one of these presets to start from. Going to cancel out of there. Just going here, you have the option of blurring a color or a monochromatic or just a black and white blur.
Blur amount is pretty straightforward. Go down here and then play with the blur relative X and Y, and if I just choose to zero out X, notice that Y, that there's just a blur on one axis. On top of that, mix this in with playing around with the brightness of the blur as well as the scale opacity, and you can start to create a customized look. Now if I go to the filter, you've got different types of blurs under this, such as Gaussian, box, as well as triangle, which could be useful in various situations.
Very rarely are you going to blur your entire clip. Should be noted that you could use this blur effect as is here, and key frame some things such as the blur amount, so if I come here to the stopwatch for blur amount, at the beginning of my shot, and move later and then just zero out my blur, notice that I created a useful transition. However, on top of this blur, you can use it for stylistic color correction effects, but let me just remove the blur and show another way that you might want to be able to use it.
What I'd like to do is add a blur, but really only have it around the subject, or basically have the subject in focus and the surrounding area, but everything else blurry around him. This is where masks could come in handy. I'm going to use the handy help of an effect in Premiere Pro, so let me apply S_Blur to the clip. Just load a preset to start. Let's say that I'm really into the Steamy Glass type look, and I'll just choose to load that into Premiere and actually increase the blur amount as well as just the X value here.
In order to have it just blur around the subject and not on the subject, what I'm going to do is duplicate this shot, so I'm going to Alt + Option click and drag it up. On the duplicate shot, I'm going to select the S_Blur and delete it from the clip. I'm going to generate an effect on this. I'm going to go to my Generate category here and actually add a circle. I'm going to increase the radius of that circle, and I'm also going to feather it. If I turn off video one, notice that it's just a circle with a feather between the black and white values.
Let me increase the radius a little more, and I might want to just play around with its center. If I wanted to temporarily, I could go up to the opacity of this clip and just bring it down, turning on the video layer underneath, so I could get a sense for where I want this circle to be, and of course, play around with its size, just so I have it just right. I'll bring that opacity back up. What I want to do is actually just make sure that the circle is going to be seen by the blur effect as a mask.
What I want to do is right-click this clip, and from the shortcut menu, choose Nest. I'm just going to call it Circle Mask, and I'll just choose OK, and I'll actually then turn my video two track off 'cause we really don't need to see it. Now, if I go back to the original V one clip, under the blur effect, you'll see that there's the option for a matte, and currently it's set to none. If I change that to video two, what you're going to see is that the blur is right now isolated inside the actual circle.
Now, let's just say that I wanted to invert this. I could, and simply now, by inverting the matte, you'll see that the white area that we defined is currently in full focus, while the other area has this blur look that we intended for, that steamy window effect. You've got a lot of control here with your blurs when you introduce masks into the mix. Again, this is just a starting conversation. This is what you can do with Premiere Pro's built-in tools, but please tune in a little bit later to another chapter where I'll show you how you can use Mocha in conjunction with this to get even more articulated masks.
