Fixing out-of-sync audio for captured video

[jm9]

I am trying to transfer 8mm analog video recording to a dvd disk.
Unfortunately, in my a/v capture process the audio gets progressively out-of-sync with the video, up to 3 seconds after 1 hour.

I have AMD Athlon(tm) XP 3200+ 2.2 GHz 512MB RAM

For capturing I used KWORLD VS- USB2800 USB 2.0 device
I first used: http://www.kworldcomputer.com/kworldcomputer/www.nsf/h/dvdmaker
with Roxio 8 Video Import which saved the result as an AVI file.
Audio was 3 sec ahead of the video after 1 hour.

Then I tried Nero Vision Express 2 Ver 2.1.2.18, saving the file as MPEG-2.
This time the file was written to a disk other than the one the OS is on. After 1 hour audio was lagging by 2 sec.

1. Is there a way to prevent this?

2. Is there software that can adjust the frame rate vs. audio?
I tried using YAII 2.02.48 utility http://yaai.sourceforge.net/ but it could not open my AVI file -- I keep getting "The Avi file could not be opened"


This is truly frustrating. Must I buy a DVD recorder to accomplish this?

thx,

Hi!

When capturing your .AVI, use PCM (Uncompressed .WAV) audio. You can always convert/compress it afterwards...

Try capturing with VirtualDubMod - it's a known problem that many capture devices don't maintain audio/video synch, but VirtualDubMod usually keeps it.

Thanks, I will try it next weekend.

take a look how to improve AVI out of sync quickly in three simple steps:

Tried VirtualDubMod but got the worst results.

Tried both "resample audio data dynamically to match video clock" and "add/drop frames to match audio clock".

I'll try SolveigMM_Video_Splitter, but it may be simpler to work on capturing ~15 min sections at a time so that out-of-sync audio is minimal, then combining them.

I just find it disappointing that the process of capturing a video and burning it to disk is such a hack. I can't imagine an average person be able to do it properly.

If managing digital photos was so convoluted, there would a lot less people taking pictures.

Have you as yet tried my very simple suggestion? - When capturing your .AVI, use PCM (Uncompressed .WAV) audio. You can always convert/compress it afterwards...

I'll check into it next. Which means next weekend :(

Thanks.
