Audio longer than video-sync?

[vkrishna70]

I use GKnot to process the audio and virtualdub to process the video and nandub to process both as instructed in the Gknot guides.
The audio is 1 second longer than the video and hence they are out of sync. I tried besweet and same result. I am trying ot rip "Hiest" and this is happening. Earlier I tried "Abyss" and everything was just fine.
Please let me know what I am doing wrong, I am just using the exact parameters as defined in the guides.

do you happen to know what's the A/V delay value ?

please mention the title (movie?) you're trying to backup.

Hi-

He said the title was Heist-the Gene Hackman, Danny Devito recent DVD release. I didn't have any trouble with the audio, but I do my audio separately from GKnot. I got the AC3 from Smart Ripper, although DVD2AVI works just as well, and then used HeadAC3he (no offense to your fine program DSPGuru) to get the mp3. HeadAC3he takes care of the delay by default, but you don't usually see an audio delay of a second as vkrishna70 says is occurring. If it's a fixed asynch, it's easy enough to fix. If it's progressively asynched, it's harder to fix, but still possible. In Doom9's VDub guide is a section on fixing asynch (although that doesn't really answer the question of why it happened in the first place).

This is what's happening :
I was using DVD2AVI 1.85? so the audio was 1 second longer than the video.

Now I use dvd2avi 1.76 to get the d2v file and the ac3 file,
Use Gknot to process audio/video, I use virtualdub to process the video. I played the video separately and audio separately and now they are fine , they are both 0:30 seconds long,

The video has no jittery frames where the frames stop in between and the audio is perfect,

Now I use nandub to mux the audio and the video and the problems begin,
The video has stuttering/jittery frames which freeze in between and the audio goes completely out of sync.
Anyway this can be corrected using nandub ?
I am using the version of nandub as in the Gknot package.

It could be your player. If you're using the "Playa" or the "DivX Player" ... you'd get symptoms like these.
