Now, once you know Photoshop, it's like I know exactly where everything is. They may know their editing tool, but they look at After Effects and it's really scary, kind of like the first time somebody ever looks at Photoshop. One is, do it in a compositing tool, the other is do it in the editing tool, and what's the logic there? - Well, for a lot of folks, they're uncomfortable with jumping into a, what they call a higher end tool, like After Effects, they're a little afraid. There's really sort of two schools of thought. And we're going to take a look at a couple of techniques here. So, when it comes to keying video, it's a lot harder than keying photos. (laughs) But as they move around, they turn their head, the light hits differently, they start waving their hands in the green screen space, and you get vibrations, you can get these areas that just don't key very well. So we can stop now, we're making him dizzy. And you deal with the fact that you don't have to just make a single frame look good, you could be dealing with hundreds, if not thousands of frames, and as the subject moves around. The highest of hi def televisions are only 1920 by 1080, that's less than two megapixels. Absolutely, and not only is the quality worse, because of the compression, but even the size of the image.
With a video, because of the way video cameras work, so much information is smashed and thrown away, especially on a DSLR, that it's like you're working with a JPEG quality one photo, when it comes time to do the key.
You can get in there and really refine edge detail, and things like clarity, to just pick up those edges, it's perfect. You could recover the highlights, or bloom them, so you get a nice perfect key. So, when you're dealing with a high quality raw file, you've got tremendous latitude. Yeah, I think where the problem comes is that it's such a lower resolution medium. Now, working with video is very different than working with a still image, and though some of the techniques are similar, it's kind of a whole different ball of wax. Now, Photoshop was pretty straightforward, and I think it serves as a great foundation for what comes next.
