Complex Colors: Green Screen / Blue Screen Keying - After Effects CS4 & Keylight

Using After Effects CS4 & Keylight to chroma-key a dual key on one piece of footage - creating a "chroma sandwich" of sorts between the two colored planes.

NOTE: YouTube screws up the first few seconds by over-compressing the video, but it clears up quickly!

Yes Keylight will leave the shadows in the second pass on the blue.

The first few seconds are just Santa begging to peek around the blue panel - YouTube compression failure, that's all! ;)

@pxlpainter so does the keylight capture the shadows? I'm not exactly clear on that. Is that what was shown in the first 3-4 seconds?

@Danayru - also you can read the step-by-step tutorial here: pixelpainter[dot]com/complex-g­reenblue-screen-keying-after-e­ffects-cs4-keylight/

usually how much green walls do you need and how much does it cost and what program???

[pxlpainter]

@Esnip3 - that's a very vague set of questions and about a hundred different answers.

Background + proper lighting and scoping your camera properly are the first steps. Several software solutions for compositing out there - Keylight ships with Adobe After Effects. - If you're serious about learning the entire process, including how to build your own lights and shoot on the cheap, then check out my book "The Green Screen Handbook" on Amazon.

@pxlpainter well i got a HD camera ready to roll and is Vegas Pro 9 good enough?

[pxlpainter]

@Esnip3 - I've never used it but if it has a decent green/blue screen keyer then I'd say sure - why not? If it doesn't then look for a good third-part plug-in like Boris Continuum (I don't know if it's compatible or not). Your basic keyers that are built in are usually crap - even in Final Cut. The "key" here is to make two passes with it and adjust the second pass on the blue to retain the drop shadows.
