|Before and After|
The footage I am using was captured directly from the EX1 to ProRes4444 using an AJA break out box for Rachel McLean's Scottish Arts Council project. I now realise that 422 chroma sampling is all we were getting out of the camera but I'm sticking with 444 to avoid a rerender.

This tutorial covers the whole three-pass keying process but doesn't discuss the principals of keying or KeyLight in any depth. For a KeyLight tutorial, check out Andrew Kramer's video here. A still frame of the footage is available here for anyone wishing to follow along.
