[AG-TECH] AVCHD and AG

Tue Jan 20 21:06:20 CST 2009

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).

thanks,

-gurcharan
