AVI- to dvd audio sync problem

[petesouthwest]

Hi

I've been trying to convert an AVI into mpeg so that I can put it on DVD using TMPGEnc. I save the sound as a .wav first using virtualDub, following these instructions https://www.videohelp.com/virtualdubaudio.htm then use this as a source for the sound in TMPEnc. VirtualDub does not report any errors, even when I scan the video stream. I've been trying to convert using the instructions here https://www.videohelp.com/tmpgencdvd.htm but selecting PAL.

However, the audio is always out of sync. virtualDub says the audio is 2 chennel, 128kb bit rate.

I'm new at this so sorry if it is in the wrong forum, but I'm stuck and any help would be apprecieated.

did you convert to an uncompressed wav? it should be around 10MB/minute.
what is the source frame rate in the avi? check with virtualdub or avi2clipboard.

or just try something else like divxtodvd.

I personnally use a program called Goldwave to extract/edit audio.

If the audio is a constant time out of sync (ex. 1 second too fast/slow), you can use Goldwave to add/remove 1 second of time. If the audio is a variable amount of time (ex. starts in sync then gets progressively worse) out of sync, then the problem is most likely not correctable, at least not in my experience.

Often, it is just a matter of trying different software/tools, until you can find something that works (although virtualdub and tmpgenc are very popular and reliable).

If the audio is a variable amount of time (ex. starts in sync then gets progressively worse) out of sync, then the problem is most likely not correctable, at least not in my experience.

Use the Time Warp feature under Effects in Goldwave and change the time of the audio to match the time of the video.
This is usually easier to fix than constant sync since you have to experiment with adding or subtracting audio to get it right.
