Repair AVI Index (uncompressed)

[Andorian]

Hi All,

I have an AVI file that I recorded through VLC. The video is in AVI format and is uncompressed.

The issue was the file did not close correctly when I created it and there is an issue with the index.

The file is 156 or so gigs and lists that it is 56 minutes long and has 100,000+ frames (recorded at 30fps)

However, when I play it via VLC and it tries to rebuild the index, the recover lists only 40,200 or so frames.

I did a conversion from frame to jpg and it pulled off on the 40,200 or so.

Can any help give me a hand to figure out if the remaining frames are still there and if there is any way to extract them?

I should mention that I have tried all the usual suspects of DivFix++ etc. (with the file being so large many just fail outright because of file size)

Many Thanks,

Andy

What happens if you open it in VirtualDub?

It opens, repairs the index, but only extracts 40,129 of the 100,000+ frames that are in the file.

I get the 100,000+ frames from opening the file in GSpot, it indicates that there are 102,013 frames and 59 min of runtime.

From the VirtualDub repair I get 40,129 frames and about 29 min of runtime.

try with avidemux

I tried, however avidemux will not open the file.

If you can find a hex editor that handles files that large, try to confirm:

1. There is actually data in the latter half of the file.
2. It appears to follow the structure of AVI.
