I really need Key-light suggestions

[Steve Blacker]

Try adjusting the clip black and clip white parameters.

It’s only work if you’d rather be doing something else…

[Kyle Omlor]

Maybe I’ll upload a screen capture of what I’m doing. I’m clipping Black, clipping White, Screen Gain, doing everything I can think of, and it never comes out right

Don’t try to use one instance of the keying effect on one layer to create your matte.

This is a very important conceptual hurdle for people who are new to color keying to get over.

The best multi-pass keying technique that I know of is described in Mark Christiansen’s After Effects Studio Techniques book.

There’s also a pretty good set of tutorials by Andrew Devis here on the COW. See this: “color keying tutorials from Andrew Devis (and more)”

From what I see in your post, it looks like you may have DV or similar type of 411 compression in your footage. Not a good choice for chroma.
Here’s a good tutorial on Keylight:
