Recovering portion of corrupted .AVI

[homestarmy]

A friend called me frantic because somehow the first 30 seconds of a video project that he's been working on became corrupted.

He has the file in an .AVI format, and he can play it in VLC (which just skips the corrupted portion and plays the rest), and he also has the first 1.5 minutes elsewhere which he can splice in. The problem lies in the fact that he can't open the .AVI file elsewhere because it's screwed up.

Do you guys have any idea on what he can use to recover the non-corrupted portions of the .AVI? Any thoughts, even theories would be super great. Any helpful direction would be great as well.

(He's not posting this because his internet is down as well - what luck!)

He could trying opening the corrupted video in virtual dub making sure to delete the corrupted part (making sure to delete it up until the correct frame) then splice in the non corrupt video.

Use virtual dub to render out the avi as individual frames, umcompressed.
It will be a large file but will let you clean it up and re-encode it properly.

open in virtual dub with the extra options of rederive keyframe tags. then cut it can't hurt to try.

Thanks a lot for the info guys! I forwarded this link over to him now that he's online.
