Audio/Video out of sync

I have several videos on DVD that I need to edit and burn back onto DVD. I have done this successfully for 7 years using Vegas Ver 8. Recently the videos have gotten out of sync with the audio.

I have imported the files from the DVD into Playhome memories and now directly into Movie Studio 13 Platinum build 879. The DVD and imported MPG files are in sync in Vegas, but when I render them (“make movie”) to a new MPG file it becomes out of sync.

I have tried these solutions in this order without success:
1. Uninstall & reinstall Vegas 8
2. Reformat and rebuild laptop
3. Upgrade RAM from 4 GB to 8 GB
4. Upgrade hard drive
5. Upgrade Vegas ver 8 to ver 13

Hardware:
Laptop (Sony Vaio VPCF116FX) Intel Core i7
Windows 7 Ultimate, SP 1, 64b OS

I need to be able to edit the video down the frame which is why I use Vegas. But if it is out of sync my $250 worth of upgrades has been a waste of money. What is wrong?

You need to absolutely slow down, as I see it, because you are just thrashing around with the tech.
1) Is the DVD source you are copying legal? Unprotected?
2) The best way to use DVD source .vob material is to extract it directly from a copy on the harddrive - search the VegasPro forum for Gary James method - DVD import.
3)Check your timeline once the Mpeg2 file is on your timeline for any gaps or spaces that set sync off balance of audio with video.

Do you ocassionally use USB hard/SSD/flash drives in editing?

The DVD source is created from a video tape using a JVC mini-DV/VHS VCR to a Sony multi-function DVD recorder. When I play the DVD in a DVD player everything is in sync. But the video needs to be cleaned up and edited. The video is in sync in Vegas, but it goes out of sync when I save the edited version as a MPG. I have also tried MT2S. It is also out of sync.

I have also imported the IFO file, trimmed the begginning and end. When I saved as MPG, it was out of sync, although the IFO is NOT out of sync.

I have put the files in PowerDirector and saved as MPG without any problems. The problem with PowerDirector is that I cannot edit down to the frame and it just isn't as powerful.

I am really confused as to why after 7 years this started happening.

I have used a sata hard drive. I did think that was the issue so I put the data on the same HD as the Vegas program. No changed in sync.

Do you have a firewire port in your computer? If so, you should be using that to capture directly from the tape deck. Going through the DVD recorder on the way causes all sorts of quality loss and other havoc.

Not everyone would agree with that.

The VCR does not have fire-wire. I am going from the VCR to the Sony DVD burner using S-Video. Like I said I have been doing the same setup for 7 years without any issues. It just began getting unsynced last week, only when I "make movie" not matter what format I choose. This is an issue in Vegas.

I tried something different today. I copied the video to DVD as stated above. However I copied the DVD to my HD. Then in DVD Architect I imported the .IFO file as suggested by Gary James. There are not sync issues this way and everything is fine because these videos only have to be trimmed at the beginning and end. However, I have several that need editing throughout the video. If the rendering continues being out of sync this is a HUGE issue for me.

Update: Although everything looks perfect in the DVD preview, it is not synced when I created the DVD itself.

This is very frustrating!

Does your MiniDV cam have FireWire? Since you seem to have done video-passthrough, you may be able to use VidCap to capture your VHS tapes straight into the PC.

There's an app called VideoReDo that some of us, including me, have that has a Quick Stream Fix utility that can fix time code issues that your video appears to have. It doesn't present itself during playback but affects the rendering. You can download a 15-day trial of it to test/fix your OOS issue.

The original video is in sync. That is not where the problem lies.

The video becomes out of sync when I render the video after editing. OR when I create a DVD in DVD architect 5.

You get oos when rendering to mpeg in both 8 and 13?

What render template are you using?

As a test, render the video using the MainConcept MPEG-2 > DVD Architect NTSC Widescreen (if appropriate) video stream to create a .mpg video file.

Then render again using Dolby Digital AC-3 Studio > Stereo DVD for the audio.

Bring both files back into Movie Studio and see if they are the exact length down to the frame. If not, one of them has a corrupted timecode.
