- Keylight has a number of options under the view menu…that you don't really need…and one in particular that you must actively avoid.…Here's the lowdown on why you generally only see me work…in either status or intermediate result view.…Let's actually start with the view that you must avoid.…So here in the intermediate result…I have my initial key.…And if I play it back…just take note of how the foreground figure works.…
Now there's some noise going on in the background…and that is actually an area…where there's some translucency in the frame…so the noise you're seeing there is actually just the result…of those being semi-opaque pixels…because they're a weird color.…However if I switch to final result…you're going to see the same graininess on his shirt.…Check this out.…So all of a sudden his shirt which is gray…is intensely grainy.…This happens very constantly…with final result view…and for this reason alone…I would discourage you from using it.…
Not to mention the fact…that the main benefit of final result…is color correction…

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.
