Cause of faulty time indication (AVI) & fix ?

[Seeker47]

You get a video that reports itself (at least in VLC) as being over 9 hours long, when you know that in fact it can't be any longer than, say, 45 minutes. I'm thinking this must be due to an index that is farkled ? O.K., if so VideoRedo has an Index Repair tool -- but for .Mpg only -- which I have used a few times. I think those results have been mixed, which is to say it did not always work.

What would you use on an AVI though ? AVIdemux ? Offhand, I don't recall .WMVs or .MP4s, or Matroska being particularly susceptible to this problem, but while I'm asking, might as well extend this question to the other formats.

Remux with avidemux, ffmpeg, etc.

If it's an avi with divx/xvid then try divfixpp.

Thanks, Baldrick !
