mmmh, your response is certainly true..but consider this problem : I have 300 frames of a Man against a blue background. Bacuase of lighting and camera resolution etc..the Background *IS NOT* a constant RGB value. I want to Composite the man onto another image. What I do know is that Blue will be the dominant color in the background…However, just replacing pixels where B>G and B>R won't work because blue eyes will become background colour *AND* the shadow of the man on the blue background is lost! This appears to be quite a tricky piece of logic and I can't figure it out.. ….*YET* ..Video Post will only cut it if the area outside of the man is a solid consistent color. VP will let me do Luma keying, but as far as I can make out, true ChromaKeying is not possible. SK.
