Yes. http://florin.myip.org/soft/conv-dvd/ If you look at the "grab" script, dvgrab is configured to start a new file whenever it encounters a scene change in the DV stream (whenever I paused or stopped the camcorder). So a DV tape is saved as a bunch of .avi files, each file being a different scene. Sometimes I edit a file or two with Kino, then mass-transcode and author the whole thing into a single-title, multiple-chapters, no-menus DVD. > So you "only" have a bitrate overshot, but mplex multiplexes the files > without a problem ? The sample I have mplex puts out a warning ( data > will arrive too late) and breaks after several such warning messages. The parameters I'm using are: mplex -f 8 -S 4400 $out.m2v $out.ac3 -o $out.vob mplex appears to not care about what I define as "too high bit rate". The target format is DVD, and there's a limit to the total bitrate of all video + audio channels. What I'm worried about is that due to the rate control issues, the DVD will exceed that limit. I've had enough problems with crappy DVD players and I want to avoid that if possible. After all, the reason why I've been using mjpegtools and not ffmpeg to generate the MPEG2 tracks for quite a few years now is rate control. Well, last time I checked the image quality was better too, so I'd like to keep using mpeg2enc for all the MPEG2 encoding. -- Florin Andrei http://florin.myip.org/ ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
