Great would be something which allows for reencoding 10 times and is still hard to see...
The two DV-Codecs (ffmpeg, libdv) are currently really bad if compared to commercial solutions (Canopus/Panasonic). > AFAIK libdv is in deep maintenance mode now and I haven't > seen any evidence that there's any work going on to find and fix the DV > encoding bug. As far as I have understood it, they think of it being "finished". So I hardly expect there to be any further improvement with libdv... > As for ffmpeg I haven't tested the DV encoding functionality > of recent versions so I don't know what its status is. > Far better than libdv but still not good. (BTW: the mpeg2 encoder in ffmpeg is fast, yes... but not good either...) cu Stefan PS: if you want to have the best video-quality you can get out of cinelerra then export your projekt to a y4m-stream and a wav-stream seperately and encode this with mpeg2enc and mp2enc (or if ac3 needed with ffmpeg...). And BTW: *do not* use Jpegs for titles or something. Use PNGs. (if your hard-drive can hold that much data...) ------------------------------------------------------------------------- Take Surveys.
