dvd -> avi and audio sync
I'm trying to back up all my stargate DVDs to divx.
Right now I'm working on the pilot.
With dvd::rip - the resultive avi file has audio sync problems. In some parts of the film, it seems perfect - but in other parts, the video definitely lags behind the audio.
I went to
and did the following from that page:
cat *.vob > movie.vob
tcextract -i movie.vob -t vob -x mpeg2 > movie.m2v
tcextract -i movie.vob -a 0 -x ac3 -t vob > movie.ac3
(I did not resize)
mplex -f 8 -o final.mpg movie.m2v movie.ac3
The result - final.mpg - has perfect audio sync.
I'm not sure what is causing the difference when transcoded to avi (using xvid) but somehow - whether it be using the dvd::rip gui or using transcode from the command line - I'd like to make proper avi files with proper audio sync.
The goal is to put a season's worth of avi files onto a DVD-R so I can watch those when I get a stargate craving, rather than my DVDs. But I don't want to be stuck with poor audio sync.
Any tips at all with respect to how to get to avi with proper audio would be greatly appreciated.
Just back it up into one MPEG-2 file: mplayer dvd://1 -dumpstream -dumpfile rippeddvd.mpg
You can play with mplayer options to strip unneeded audio tracks.
Edit: Didn't read your whole post. I'd recommend using Avidemux2 for transcoding. It will give you full control over sync.
I got it to work - I took the transcode command that dvd::rip was using and changed -M 2 to -M 4 on the command line - it took a lot longer, but the audio matches the lips now.
