user6542: Is there any free software available for green-screening? I prefer Linux, but Windows is also fine. 

user2994: Depends on what your definition of good green screen is.
In terms of free software to do green screen well...Only one that I can even think of that does keying is Da Vinci Lite which is free from blackmagic's website.  It is pretty complex and pro based, but with a little searching around you might find what you want.  I am not sure if you can technically do green screen with it though.
