MPEG 2 Audio / Video Sync Issues

Hello -

Made the plunge and purchased VV4/DVD-A this week!

First issue though. When using some rather large .avi files I have and putting them into DVD-A, everything seems fine. But when I render the DVD and burn it, the audio is off sync with the video. I thought it may be DVD-A, so I re-rendered the .avi in VV4 to an MPEG2 and it did the same thing.

Any ideas how to correct this?

Thanks in advance for the help!

Nobody?

(duplicate post from vegas forum)

We've tested very long files but I'd be happy to look at this again.

What is the orginal source format?

How was the original source format captured? (what app, what card)

How was the original source format rendered, and what apps were used?

Were ANY 3rd party apps involved in the capture/render/author/burn process?

Anything else that will help us reproduce this will be helpful.

Thanks

Hey SonicEPM, here are the specs of the .avi I am using. It is some old movies some friends and I made in sixth grade that my friend encoded a long time ago, here are the specs:

- The file is a .avi, I believe he recorded it from VHS, he recorded it last yearn and will try to get a hold of him to ask.
- Kind of like the first, not 100% sure of the source, but the .avi sound is perfectly in sync
- Resoution is 352 x 240, 1 Hour 42 Min Long, MPEG-3 Audio, 29 FPS, 108kbps Data Rate, 24bit sample, DIVXMPG4 V3 compression

Thanks!

This is going to be a very difficult if not impossible problem to solve...unless you can dub the original VHS program to DV first, then capture that. If you do it that way you'll have perfect sync.

I understand what you are trying to do, but non-DV capture + DIVX + MP3 + timestretching-to-resync has never been tested here at SF and should be considered an unsupported process.
