Is there anybody that can help?!

[claymca]

First of all I shearced the forums and tried the suggested fixes. Nothing worked. The problem is I have an avi file that plays fine. Now when doing the conversion the audio goes out of synch some where in the middle of the movie. Now before you say do a search. The problem is when the audio is seperated from the video there is a 13 sec differencr between the two. The video file has a time length of 20:42 while the audio is considerably shorte at 20:29. Is there a fix for this problem. I have Ulead Media Studio 6.5 directors cut. is possible to fix it with this prog. Or is there another fix out there? Please help as I am at my wits end.

You are going to have to stretch the audio by 13 seconds. Load your file into Gold Wave. Select Effects-->Time Warp (I am at work, but I think that is the right menu for Time Warp).

When the selector pops up, enter the exact length of the video, right down to the fraction of a second. Save the file as a .wav file. Load TMPGEnc, load the original video as input video, load your new stretched audio .wav file as input audio.

Select Start. Your resulting file should be a video file back in synch.

You are right. I tried to do a search for the reference for this procedure, and came up empty. I do believe I saw it here, though.

or use Cooledit ...it has an option to maintain pitch. Usually stretching audio will result in a pitch shift.

Have you first scanned for junk frame with Vdub, if there is any you cannot do anything until you remove them, and maybe cure the audio problem.

When I run vdub to check for bad frames it gives me "0 frames masked (0 frames bad, 0 frames good but undecodable)". What does this mean?

It is a good video file. Go ahead and stretch the audio, multiplex it, and see if the pitch changes.

Ok, well its telling you that no bad frames were found, if the audio is out of sync the same all the way through the movie, then someone else did a bad job of the copy. If it starts out OK but later goes out of sync, then I would still suspect bad frames, despite what Vdub says. I would probably use "vdub-mp3-freeze.exe" just to make sure

Did you separate the audio ?, if you still have the original file, you could try that in TMPGEnc as it is, without separating the audio. Its very rare to see audio and video at different lengths unless there are problems frames, and the person has edited them incorrectly.


You can use an audio delay in both Vdub and TMPGEnc
