Audio sync problem after 2-8 minutes of bad frames

[MegaDave]

First, I just want to say that this site has already been a life saver, and this is only my first post. I am very, very glad to have found it, and I look forward to reviewing all the information here.

Now, I do have a problem I can't seem to fix.

The source is an .avi file, and I am running it through TMPGEnc first. Then I am putting it into Nero, authoring it, then burning it. It is working fine for some VCDs, but occaisonally I am getting some audio sync problems.

I keep getting some bad frames, they pixalate out, jump around a bunch, then after anywhere from 2-8 minutes, the frames are fine, but now the audio is bad. I tried converting the .avi audio to .wav using VirtualDub, but all I got was up to the first part of the bad frames, then it wouldn't convert anymore.

Anyone know what is going on, and how to fix it? Both for the bad frames and the audio sync problems.

If the source avi files were downloaded off the net, there's not a heckova lot that can be done.

If you are capturing the files from your vcr/tv/etc, pls post related details.
Bad frames and sync loss are often related.

The file I am having problems with is off the net. I haven't ever tried to burn anything off the net before, only from a digital camera source. I don't know much about getting stuff off the net. Should I look for a better source, or is this something that happens to anything you get off the net?

From what i've read, results can vary from file to file, particularly the "freebies" found on p2p sites.

Also keep in mind that a video file with the extension of ".avi" cna contain a wide variety of video files, much as the term automobile can mean a bunch of different makes/models. The same could be said for an mpg file.

m/w, take time to read and research the csategories over on the l/h column, starting with the "how to" series. you'll find a variety of guides and tools that can help you to salvage "bad" files... but it will also take you a bit of time/experiemting in slecting/applying the best methods to a given problem

To get more specific details about an unknown avi file, use AviCodec or Gspot - both freeware utilities.
