Bonjour Pierre, Here is my workflow : - input = PAL DV - work, work, work, work on my project - render in Quicktime DV to see what the parts look like. The file is perfectly played with mplayer - I export à YUV4MPEG - I use mpeg2enc to encode to mpeg2 with : /usr/local/bin/y4munsharp | /usr/local/bin/yuvmedianfilter -T 3 -t 0 | /usr/local/bin/mpeg2enc -v 0 -n p -a 2 -r 32 -4 1 -2 1 -F 3 -B 256 -b 7500 -f 9 -o $1 - I export mp2 audio from cinelerra - I mplex everything with -f 8 option
The video is "bottom field first". The video is jerky on my standalone (Philips) DVD player. The "speed" of the DVD isn't constant. It doesn't stop either. It just plays slowly for a 1/10th of a second, and restart at the good rate for 1 second or so. It plays fine on my computer using mplayer to play it. I tried to export mpeg2 directly from cinelerra, and it fails: FileMPEG::open_file: Running /usr/local/lib/cinelerra/mpeg2enc.plugin -b 7500 -q 0 -a 2 -F 4 -I 1 -M 1 -z b -f 9 -g 45 -G 45 -R 0 -o '/mnt/Seagate_200Go/video/chevreuse/dv_output/export_direct_mpeg2_depuis_cinelerra.mpeg' **ERROR: [mpeg2enc.plugin] -q option requires arg 1 .. 32 I try to export using fixed bitrate. The command line shouldn't include -q by the way... It also fails if I export using quantization : Running /usr/local/lib/cinelerra/mpeg2enc.plugin -b 0 -q 10 -a 2 -F 4 -I 1 -M 1 -z b -f 9 -g 45 -G 45 -R 0 -o '/mnt/Seagate_200Go/video/chevreuse/dv_output/export_direct_mpeg2_depuis_cinelerra.mpeg' **ERROR: [mpeg2enc.plugin] Sample rate is greater than permitted in specified Level I just exported RawDV. Audio is out of sync. Quicktime DV can't be used to encode. Or at least, I don't know how to encode into mpeg2 suitable for DVD. I'm just lost. I don't know what to do. =( Nicolas.

Jerky could be "skipped frames" (I haven't seen) or "incorrect > interlacing order".
