Odd Sync Problem

About a month ago I video taped (VHS, not TiVo) a special on TV and want to convert it to DVD and cut out the commercials. So I captured it with my analog capture card and watched the AVI in WMP and it looked fine. I import it into Vegas, and the audio starts in sync and exponentially gets worse. So its not like I can just move it over, it starts fine, but by the end its a couple seconds off. At first I figured the preview was just lagging, so I rendered it...renders exatly what I see on the track. (This is without editing, it happens if I just drop the AVI onto the track.) Its weird too, because if I scroll down to the end of the AVI, the audio is longer than the video.

Any suggestions?

Thanks!

Ctrl/Drag the end of the audio to line up with the edge of the video.

Well, lining up the ends doing Ctrl/drag did not do anything, but if I try to sync the end manually with that technique, the beginning and the end are in sync, but the middle is still out of sync...

So I try using a different editing program I have stowed away on my machine-Nero VisionExpress, and it has the audio and video in sync just fine. Maybe a bug in Vegas? (The AVI is 45 minutes long...)

Any more suggestions? I suppose my last resort would be to re-render it in Nero as maybe an mpeg and bring it into vegas that way...

Thanks in advance!

Re-rendered the video as an mpeg in Vision and Vegas did not like the mpeg...I think maybe it was originally a bad file. Which kills me because that's the only analog capture program I have (AMCAP)...and I really don't want to reinstall Pinnacle-that's like asking your computer to stop working.

Has anyone else ever had this problem with out of sync audio in Vegas but other media players playing it fine in sync?

Thanks again!

I think this issue has been discusses here before. The problem is that you're recording vision and audio throught different devices, if you use a firewire A->D converter (ADVC-110 etc) the problem doesn't occur.
As to why you cannot get it back in sync using ctl-drag is a mystery unless the clocks were drifting quite badly. I assume you unlocked the A and V prior to ctl-dragging the end of the audio?

Yes I "unrippled" the two clips. After about 2 hours of analyzing...I beginning to wonder if my eyes are playing tricks on me.

The video I'm trying to convert is CBS's Category 7: The End of the World and after watching the tape through my TV, I realize, a lot of their audio is off...just by one or two frames, but it was magnified by the fact that I do capture the audio and video with two different devices.

I downloaded uiVCR to capture the clip, and it did a much better job of keeping the OOS like the original....so I'm good now. I'm not going to try to fix CBS's mistake. :)

Thanks for everyone's help!
