vob file audio out of sync

doctorfish wrote on 1/23/2006, 2:42 PM
I've done some searching in this forum and found some suggestions that said rendering the VOB audio to a wave file first and then using that to replace the vob audio when re-rendering the video to other formats would help with sync issues but I'm not having any luck. The vob files themselves are OK but any time I render (to mpeg,avi,or mov) the audio is losing sync with the video.

I only have Vegas 5 so was wondering if Vegas 6 was better suited to this task or if anyone has run across the problem but solved it in a different way than what I mentioned above.

Thanks

Dave

You can resync mpeg audio with MPEG Wizard from womble.com You just drag the VOB to the MPEG Wizard timeline, then drag the same track down to one of the audio tracks, mute the audio on the first track then slide the second track ahead or back until it lines up properly. When you render it, it will smartrender so there's no generation loss.

I have to do this every so often on M2T files as the audio sometimes gets captured out of sync.

How would this be different than doing the smae thing in Vegas? I was doing this on my laptop so was perhaps lacking the resources I need. Not sure if processing power will add to or create sync issues. Time I think anyway to clean out the laptop, may even do a fresh install of Windows. Anyway, I seem to remember reading somewhere here that Vegas 6 was better at handling VOB files? Is this true?

MPEG Wizard offers a 30 day trial so I'll give it a shot too.

Thanks.

How far out of sync is it getting?

Sometimes things get out of sync over time because a setting is incorrect. If you render at one sample rate but the playback assumes a different sample rate well then you lose.

Well you could do it in Vegas, but it would rerender the MPEG. MPEG Wizard will do it without re-encoding the video.

Thanks Laurence. I plan to try it this weekend.

I recently did this with v18 due to drop in support for ac3 audio from vob. streams. I converted the the audio to a .wav file and my audio sync is PERFECT within the vegas preview window. However once I render it loses its place. Any recommendations for a fix?

Sure. First, you tacked on to a 14 year old thread. Better to start with a fresh one.

Second, import your VOB files from the Video_TS folder using the "Gary James Method" in an older version of Vegas; I've heard of the AC3 problem in 18. They won't come in sync individually because they are ... well, TS. Search.

Thanks @Musicvid. Going to try the .IFO import method now to see if its fixes my sync issues.
