all, what's the status of vic/mac/BlackMagic? is anyone working on that? i know doug found a little time to play with it. i'm ready to throw a student at it right now to try to get what i want--vic with uncompressed HD. let me know what you all think--is someone already working on it? is it feasible? (naturally, vic+codecs and smaller resolutions would be a by-product of this work).
