Great question. Unfortunately I don't have a great answer for you, but I do have one suggestion -- post it to the [EMAIL PROTECTED] > Unfortunately, Cinelerra doesn't allow for CLI driven rendering other > than the rather inflexible batch render functions, and I though I found > that rendering an edited project first to DV, then rendering the DV file > to MPEG, gives a noticeable quality degradation. I'd very happy to find out more about this quality degradation and fix it in ffmpeg's DV encoder. Please let me know more and especially focus on how you observe or measure it, what format your stream originates from and what tools do you use midstream.
