Video(lips) and voice(audio) not in sync

This problem occurs with a VHS capture card *.AVI file and Microsoft Media Center TV *.dvr-ms files.

Problem was on prior desktop and now on new desktop.
Prior- XP SP2, 1 GB ram, 3.0 Ghz cpu
New - Vista SP1, Intel Core 2 Quad, 2.4 Ghz, 3GB memory.
No other programs running.

Appears that original files AVI or dvr-ms are OK most of the time, but not always. Use PowerDVD7 to view original and a saved file after PD6 edit of a good source file.
But import good file into PD6 or other software (AVS Converter) and problem appears.
Beginning is OK, but the longer the video, the worse it gets at end.
See lips move and then the delayed voice (maybe I got it backwards, voice then lips move). Sync bad at end of 30 min video. Maybe a (1) second on longer videos. Can see this problem in PD6 Edit function before output to HD or burn to disk.
Think it has something to do with conversion when data is loaded. That is when I first see problem using PD6 edit play. Desired output is DVD meg2.

Did learn that VHS tape must be running before record starts and continue running after record stops. Gets video/audit in sync on AVI file.
But then lost it on import into PD6.

Saw another post with video audio sync problem, but different setup.

Any ideas on a fix???

Frame dropping is the basic problem you're suffering.

You have to edit to accomodate the loss of video to the audio.

Analogue capture.... yep a big problem, we all use to have to work around the same sort of issues. Some might offer you suggestions.

Thanks for reply.
Done more testing with different formats.
Problem appears to be with dvr-ms.
A good AVI file worked OK.
Put software "AVI Video Tools" on older XP desktop and got audio first then lips moving. On new Vista desktop, looks like reversed, video then audio. Did not put PD6 back on XP (being discontinued) for more tests.
So, PD6 fails on dvr-ms loading (converting) into Edit correctly. Saw that PD6 creates a meg file to work with.

MS Media Center only has one output, dvr-ms and it is not processable.

So, what next???

I did a quick Google on the file format you've mentioned.

I found the information interesting.

Hi Mike,
Before domestic DVD/ HDD recorders became commonplace capturing an analogue video was always difficult with a PC. I have tried various PC & Capture card setups over the years, but I have given them all up.
Now I use a bog standard VHS player, and use Scart to Scart leadt to connect it to my DVD/HDD recorder.
Once captured, I save it onto a recordable disc as a standard DVD (not an mpg)

I then use PD6 to Capture from DVD, and if necessary output as an MPG for archiving.

The results are always in sync, never had a problem.

I am not suggesting you go out and buy a VHS player and DVD recorder, but it is the best way I have found to capture analogue. Using PC capture cards just never cut the mustard.

Kintara Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so.

Mike:

I had the same problem.

I cured it by using Video Redo TV Suite. It converts DVR-MS file to a mpg, with no quality loss. It helps you delete ads as well as a number of other chores.

I been using it for about two years and I love it.
