Howdy... We're running into a problem where we have a mpeg2 dump from a video card which we'd like to be able to throw into final cut. Unfortunately, final cut can't understand mpeg2 audio (even though quicktime can, grr!). So we need to change the format. We'd like to do this in the least cpu intensive, and least quality degrading way. We've tried just about every container format (mpg, avi, mov, mp4) and just about every audio codec (aac, ac3, pcm_s16le, etc.), and have found no combination that a) ffmpeg doesn't choke on and b) plays in quicktime. Is there perhaps a compatibility matrix of video/audio codecs and container formats somewhere? Or is there perhaps a semi-efficient way to downgrade mpeg2 video to mpeg1? We've tried ffmpeg, mencoder, and some other tools. All without success. Any pointers/ideas would be *very* much appreciated.
