I need to convert some PAL high-quality divx AVIs to SCVD mpeg. I have a tool chain that works fine for NTSC sources. I use transcode to convert the divx source to a mjpeg-tools LAV file as follows:
$ transcode -i foo.avi -y ffmpeg -F mjpeg -V -N 0x1 -f 25,3 -o foo.lav.avi then use mjpeg-tools lav2mpeg script to convert to mpeg: $ lav2mpeg -m svcd -o foo-svcd.mpg foo.lav.avi I mix the tools this way because I've found it gives the best trade off for speed/quality/consistency than any of the other combinations I've tried. The same system works fine for PAL, except it gives me a PAL formatted (480x576 25fps) mpg file. My thought is that since the mjpeg LAV file is frame oriented, it should be relatively straightforward to encode it to NTSC standards. But I may be way off base. Thanks, Jay PS - The lav2mpeg step above is pretty darn slow - it takes upwards of 4 hours to convert about 25 minutes worth of video on my Athlon 1100. If that is about par for the course, fine. I just want to make sure I'm not doing something stupid to make the process slower than it has to be. -- Jay Bloodworth <[EMAIL PROTECTED]> ------------------------------------------------------- This SF.NET email is sponsored by: Order your Holiday Geek Presents Now!
