Here is an elementary video question: what is required to mix a video source (a foreground scene with a single color flat background) and computer generated graphics? The idea is to replace the flat background with the graphics. I assume this can be done with a SuperGen and some software, or with the Toaster. Is it simple? Does one method have great advantages over the other? TIA, David
