Hi all,

I have checked an avi file for errors using v-dub. It showed to have 450 or so bad frames. After deleting them, the audio ( which is the original lenght ) is becoming more and more out of sync because of the deleted frames.

Is there a way to make the audio right again for the movie, by deleting the masked sectors from the audio too? Or some other method?

Tnx.

Hi-

Are you saying that the audio wasn't muxed when you deleted the frames? You muxed it afterwards?

If that's the case, then use NanDub, put the Audio into the movie, and then delete the problem frames, and if the Audio is set for AVI Audio, the Audio portion of the bad frames will also be deleted.

just for interest, vdub will also "delete" the audio frames in a wav source, no need to mux it before cutting.

Well, it is not a wav file I'm using. It's the avi audio.

@manono, I have loaded my avi file ( video + audio ) into V-dub. Checked for errors and deleted the 450 found frames. Audio of this file seems not to be deleted, because it's running out of sync after deletion.

:(

If your audio was VBR MP3, you'll have to do the edits in Nandub, not VDub. VDub only "speaks" CBR MP3.

@jggimi, That's it. You have a point there.

But nandub doesnt seem to have the scan video for errors option like vdub does. How doe you check the file in nandub??

Hi-

It sounds as if you need the MP3 version of VDub from DivX Digest (http://www.digital-digest.com/dvd/downloads/virtualdub.html). It's about half way down. It is a hacked version that allows you to open VBR MP3s and do the "Scan videos for errors" thing and then delete without getting asynch.

Alternatively, if the problem is freeze frames (where the Video freezes while the Audio keeps playing), you can get AviDefreezer (http://www.doom9.org/Soft21/Editing/avidefreezer.zip) which will actually fix the frozen frames (usually, but not always), or DivX AntiFreeze (http://www.doom9.org/Soft21/Codecs/DivXAF.0_4.zip) (for DivX 3.11 only) which allows you to play through them.

It is just a thought.
If the problem is VBR instead of CBR, load the avi with V-dub. Choose direct stream everywhere and save it to a new name.

This will write the audio as CBR. Then make the correction.
In this way, you will save some extra work. (of course if the problem is VBR, sth I do not know:( .
