Thanks for these links, I enjoyed the videos.  What a shame the native Cinegobs plugins are Windows only, it would be nice to be able to pull a spill-matte so easily on a Mac.

I've found the Green Limited by the Average of Red and Blue technique very useful and has given me the best spill suppression results so far:

Many thanks, and absolutely nothing personal, but I have a client confidentiality issue on these particular shots that I don't want to tread anywhere near.

Chris:

Can you send me a frame. I'd be curious if I could focus in on the area you're talking about. Maybe a screen grab with some arrows or pointers showing me the area as well as a frame of the original, like a tiff.

I have found the edge decontamination of Refine Matte very useful in some situations, but not all. The two shots causing me grief this week have 1) a large amount of spill across the bare shoulder/upper arm of an actress, and 2) more than half way across the shirt on the back of an actor who is turning. Unfortunately, when I increase the decontamination range on Refine Matte, it does something very ugly to the color channel information - what looks like a edge pixel repeat, instead of a simple removing of color from otherwise detailed pixels that I wish to keep.

Check out the Refine Matte effect for the motion blur color decontamination.

I don't know if it's technically 'spill', but motion blur is the tricky thing to deal with when keying.  If the key isn't set up well then you can end up with footage that looks like it has a spill problem in moving areas - actually the screen is showing through semi-transparent regions.
