synch problem

[purerock83]

I am doing a dvd rip, after ripping the vob files with smartripper I opened them in dvd2avi. The frame rate was 29.97, progressive, film. I selected the forced film option and saved the project. I did the audio portion with vob2audio. I encoded a small portion of the film in tmpgenc and it was out of synch. Can someone tell me what to do? I read something about being able to shorten or lengthen the audio with wave length adjust but I'm not sure how to do that. Any help would be appreciated.

First - when you're saving your project with dvd2avi, there is an option to demux the ac3 track. Use it and later you can use BeSweet for the audio.
Second - read this : http://www.doom9.org/virtualdub_procedures.htm#mansynch
You should be able to find a solution over there.

This is quite frustrating. No matter what method I use to rip the audio it is always out of sync with the video. I would assume this is because the original dvd ran at 29.97 fps and when I enabled the Forced Film option in Dvd2Avi it slowed it down to 24 fps. I had to use Forced Film because without it my video had this visible line effect someone called combing. Anyway, I'm planning to make an svcd so it is encoding it as an mpeg2. I can't use virtualdub to open that kind of video right? How else can you fix the sync problem and why does nobody's guides seem to take into account that async could occur? Am I using the wrong settings in Tmpgenc? BTW, someone mentioned pitch correction, has anyone heard of this? I would love a solution to this problem. Thanks in advance.

try dvd2svcd.

Hmm, I've never encoded an NTSC-source, but anyway, the most fool-proof (that's why I still stick with it ;)) way to keep audio and video in sync is to _decode_ both audio and video with DVD2AVI. DVD2AVI has got a very good AC3-decoder and a prescale-decision. The only disadvantage is that you need some HD-space for the BIG .wav-file...
