Jesse, Hmmm... avi videos around 70MB, probably around 42 min, that seems familiar. What tv shows are you downloading ;)
With such a small source, the video quality is usually low enough that you can get away with converting it to an mpeg1 for a VCD without losing much quality. Unfortunately, divx usually has an mp3 audio stream so you will lose a bit of quality when converting to mp2 for VCD, but is hardly noticeable. I think the easiest way to do the conversion is to install the ffmpeg package and run: $ ffmpeg -i original.avi -f vcd output_vcd.mpg As long as ffmpeg recognizes the format, ffmpeg will convert both audio and video streams and spit out a VCD compliant mpeg. If you want to convert to mpeg2 for SVCD it is a bit harder because ffmpeg can't convert to mpeg2. You need to use mjpegtools and mpeg2enc. You can try something like the following to convert the video: $ ffmpeg -i original.avi -f yuv4mpegpipe - | yuvscaler -O SVCD | mpeg2enc -f 4 -q 7 -o video.m2v You'll probably need to add more options to yuvscaler and/or mpeg2enc to set at least the aspect ratio and framerate because the original avi likely won't contain that information and the other tools will get confused. It can be a bit of a pain to find the right settings, if you don't set the right aspect everything gets stretched and looks really wrong. You should be able to use the avi's audio stream directly if its mp3, or you can convert it to mp2. Then use mplex to put the two streams together. The process is mostly the same as I described in my previous message re: mpeg2 to VCD conversion. I'd suggest taking a look at the ffmpeg and mjpegtools man pages and documentation for a better idea of what options are available how to use them. Try using the first method and convert your avi's to regular VCD, it's way easier. If the quality is unacceptable you can try the second method but I wouldn't expect much. You're not going to turn a 70MB low bitrate video into a high quality dvd (you can't polish a turd :) Later, ~Scott On January 16, 2003 06:33 pm, Jesse Kline wrote: > I have some videos in avi format, my guess is that they're divx encoded > since they are ~70MB for just under 1 hour of video.
