I am working with some very poor blue screen footage, which has taught me much about chromakeying in Vegas. I have also tried the demos of Ultra 2, Boris Red & FX and After Effects. All of these demos have a feature which allows me to shrink the matte, or mask, that the chroma key produces. This is very handy in eliminating most of the spill or "halo" effect around the actors that remains after applying the chroma key effect. But after working with all these products, I find that the Vegas chromakey is as effective and more convenient (well, maybe Boris Red beats it) EXCEPT that I can't see any way to shrink the matte. Is there some way I am missing?
