Audio sync problems when converting to dvd

[broox]

Hi, I've captured some home videos from vhs using a ati rage fury pro/xpert 2000 pro and the software that came with it (video in 7.1). The highest quality option I could use without dropping frames was called:

good quality mpeg-2
video: 640x240 ntsc (525)
6.00 m bit/second
audio 44.100 khz 16 bit stereo

I've successfully captured all of the video I need and it plays on the computer using ati's player and windows media player just fine. The problem comes when I try to convert it to a dvd compliant file. I tried using both Tmpgenc xpress 3 and Ulead Video Studio 7 and both gave a finished file with the audio out of sync with the video. Please help!

Change the capture to audio 48khz.

I had thought of that, but it wouldn't give me that option. I tried extracting the audio using cooledit but it said it was unsupported. I also tried opening the files in virtualdub hoping to export the audio as a separate file and it said "no video frames found in mpeg file." I was able to load up the files in Ulead Video Editor 7 and it seemed to be in sync, but again exporting it to dvd compliant files put it out of sync again. I tried exporting the video and audio separately and joining them in Encore to preview them together and they were out of sync yet again. Is there something unusual about this kind of mpeg that would cause so much confusion?

It shouldn't be a particularily different mpg.
I suspect the desync happens because of the change from 44.1khz to 48khz.
Try some different capture software, specifically something that lets you capture at the audio and video settings you want, not some precanned setting, that's more designed for SVCD...
You can't open mpg's in virtualdub, you need virtualdubmod.

anyone have some suggestions for video capture software? I tried Ulead's and Virtualdub and they work fabulously but the files they produce are uncompressed and are far too big for my projects. I need something that can capture an hour or more at a time. What codecs are good to use without taxing my processor too much?

Try Huffyuv first. It is pretty much lossless, and will cut your filesizes down to about half.
Picvideo mjpeg is another good one. Slightly more lossy, but half again the size of huffyuv.

play with the audio delay settings,this works for me
