Audio Sync problem with Tmpgenc

[Scrow]

Ok, I have an Avi (divx) file, which i scanned for errors and fixed it, then i saved out a .wav file (44.1). Next I put both in Tmpgenc and tryed to encode to mpeg2 file, which I have done about 5 times now with other movies flawlessly. But for some reason this movie messed up. Now I have a an mpg file with the audio out of sync. Which is weird because when i had the two files b4 hand they were both in sync. When I played the video file and stopped it around say 40min then did the same with the audio they were perfectly in sync.

So for some reason tmpgenc messed them up while encoding.
I have tried many things and re-encoded just for a few minutes but everytime its out of sync. I dont think its gradual, but it may be....it is out of sync right off the start even b4 the part where i fixed the bad frames. So Im stumped.

Ive tried the guide on here using tmpgenc simple de-multiplex, and then using goldwave...but when I load the mp2 into goldwave it seems that the audio and video line up

Any suggestions would be great

sorry for the long post

Have you tried using the external audio encoder in TMPGEnc? It seems my video remain in sync when I use those. Just a thought, since you seem to have tried the normal fixes.

I had a similiar problem like that with LOTR. I tried to use the synch guides here on this site and on doom9's but they didnt seem to work.

I think what is happening is the the audio is out of synch in the DivX file you just cannot notice it because it is very minimal, but when you encode it using TMPGenc it becomes more apparent in the resulting mpg file.

I ended up having to go to the part in the mpg file where I first noticed it out of synch, then go to that spot in the DivX and cut it at that point then adjut the interleave audio in the DivX file so it matches precisely, then reencode in TMPGEnc just a little bit and see if it is on. It is a pain, and my video drifted 100ms in the middle and 200ms at the end, so I had to split it into 3 parts and adjust the interleave on the 3 different sections then rejoin them and encode.

Long, I know, but it was the only way that worked for this movie.

No, I havent used the external audio encoder in tmpgenc because i dont know what that is

I used graph edit to get my .wav file then Vdub to convert to 44.1.



Don2050, I'll try that but its hard to tell when the audio goes out of sync in the movie because it starts around the opening credits (btw the movie it the sum of all fears).

thanx for the replies
