PLEASE HELP! Audio only in part of long captured AVI file

[lehoczky]

I recently captured a home video (I used VirtualDub). It is a large file (cca 13GB) - it is long 60 min. Today I wanted to view this video and I found out, that audio plays only cca 20 minutes and not more.

Any ideas, what can it be?

Thanks

Can be the problem with non-compressed audio (PCM) in captured video? Can it be so long (about 1 hour)?

Open the video in Virtualdub and click on file -> file information (or similar). Look at the running time of the video and the audio. If they are the same (or within a millisecond or two of each other) then you have all the audio, but you may have a corruption in the file.

[lehoczky]

no, audio length is 18 min and 56,7 sec. After this point there is no audio

You are probably S.O.L

[guns1inger]

Yep. It looks like you are missing two thirds of the audio - from the 18 minute mark onwards. Looks like you will have to capture it again.

Recently, I hava defrahmented the disk partition, whre is stored this video and it freezed for a long time, but then was it ok... Could this corrupt the file?

Not likely. It probably "freezed" (apparently) due to having to move such a large file (13GB) as part of it's defragmenting process.
