Re: Green screen issue! Please help!! Oh God please someone help!

And I can recommend both THE ENCYCLOPEDIA OF VISUAL EFFECTS and DIGITAL COMPOSITING FOR FILM AND VIDEO books as invaluable for dealing with tricky compositing situations, both available here at the Cow's Amazon store. Steve Wright's book in particular has some great techniques on pulling difficult keys, including stuff like channel shifting and channel clamping in which you are using the Color Correction nodes to pull down the green channel in the foreground actors/objects, etc. in order to get rid of green spill, which can work wonders. (Right now I'm working on footage that has so much green spill that some of it I have to do a full roto job no matter what.)
