Hi there, I have encoded successfully a small xdiv avi into vcd/svcd-ready mpg files: ffmpeg -hq -i xdivmovie.avi -target svcd ./mpegmovie.mpg ffmpeg -hq -i xdivmovie.avi -target vcd ./mpegmovie.mpg PROBLEM: That said problems arose when I attempted to encode a large xdiv avi into multiple vcd/svcd-ready mpg files. Using ffmpeg to split xdiv avi into three parts, the second and third parts when played gave video and audio are out of sync. Here is what I tried: 1)hand-carved the input avi into three different parts. ffmpeg -hq -ss 00:00:00 -t 00:45:00 -i xdivmovie.avi -target svcd ./mpegmovie1.mpg ffmpeg -hq -ss 00:45:00 -t 00:45:00 -i xdivmovie.avi -target svcd ./mpegmovie2.mpg ffmpeg -hq -ss 01:30:00 -t 00:23:22 -i xdivmovie.avi -target svcd ./mpegmovie3.mpg Why is ffmpeg giving me video/audio sync problems when I encode only parts of the xdiv avi? ANYWAYS SOLUTION: The following strategy works with no video/audio sync problems. What mpgtx does differently? I don't know but it works for me :) ffmpeg -hq -i xdivmovie.avi -target svcd ./mpegmovie.mpg mpgtx -s mpegmovie.mpg [-00:45:00] -b mpegmoviepart1 mpgtx -s mpegmovie.mpg [00:45:00-01:30:00] -b mpegmoviepart2 mpgtx -s mpegmovie.mpg [00:01:30-] -b mpegmoviepart3 From there using a tool like k3b works to burn using these mepgmoviepart files. The aspect ratio is not ok but if the svcd is in the computer I know if I change the aspect ration to anamorphic, it fixes itself. I hope this helps. Cheers, David Marceau
