- Now I said before that Screen Color…is the most important setting to get correct in Keylight…and it's also the first setting that you create in Keylight.…So to get this optimally correct,…let's take a close look at how to make…the rest of the keying process go more smoothly…by nailing this one adjustment.…To do this I'm going to recommend…a special custom little setup and it just takes,…I think, three steps to get there.…The first step is to open up a Layer view…and to grab that tab at the upper left…and just drag it down so it's side-by-side…with the Comp view.…
The next step is to make a little adjustment to that view.…So we're going to be working initially in Status view,…and I'm going to go ahead and Reset.…We're going to start over with our Screen Color selections,…so we'll go to Status view here.…We don't want to see Status in both views.…And by the way, if you're curious why…this is red right here,…that's just a result of the garbage mat…that I have around there, you don't need to pay attention…to the fact that that's red, it's not really a worry.…

12/6/2014Beginning with a brief explanation of the keying process, Mark takes you through the steps involved in creating a perfect green-screen key: generating a rough matte, eliminating color spill and matte lines, and refining problematic edges. He shows how to work with Keylight and Primatte—two indispensable keying tools in After Effects—and explains when to use one over the other. And for times when green screen won't work, he shows how to generate high-contrast mattes, or luma keys, based on the luminance data in your footage. Last, learn about compression and how to prep a shot for keying.
