Corrupted Blocks in AVI

[Daners]

Hello,

I have a wedding video that I captured. Several .avi files comprise it. One of my avi files has corrupted blocks according to virtualdub.
I do not know why they are corrupted , but how can I correct this to get any editor to open the avi?

The file crashes virtualdub, Tmpenc, Pinnacle Studio7.15 ( which I used to capture the movie ) , Ulead Video Studio6.

It is encoded in Indeo Video5.

Any other programs out there that might let me open it to get it edited or fix the corrupted blocks?

Thanks
Daners

I know you said it crashes VirtualDub - but have you tried VirtualDub's scan for bad blocks option?
I can remove those frames that are corrupt and hopefully recover the ones after.

D_Knife,

Do you mean VirtualDub's Scan Video Stream for Errors?

I got VDub to open the file finally. It went through a process Reconstructing Missing Index Block ( aggressive mode ) while it opened the file. Then, it gave me an error message...Vitrual Dub has reconstructed the index for this file. But, you have not specified rekeying in the extended options. Seeking may be slow.

Should I reopen it differently? I tried the Shift+Open file and tried to rekey the file, but it crashes at frame 2040.

The file now open has no keyframes.
So what do I do next?

Index Block is a method of describing Keyframes (among other things)
because VirtualDub can't find or read it, it's trying to manually rebuild it.
This will happen each time this file is opened. You can try and save it with full processing to re-create keyframes (which decompresses and then recompresses again - Bad ) or if you have the original media re-capture the file again.

Do you mean VirtualDub's Scan Video Stream for Errors?

It is a menu option on the video menu - try it.
it will try and drop bad frames - although some of the time this wrecks the AVI - most Divx varients survive but older files don't. The more keyframes in the movie the better chance it will be OK.

Really though it sounds like recapturing would be the best option. If you have the original media

D_Knife,

Thanks for all your help.

I remembered I had burnt a VCD last spring with this wedding and ripped the .dat file back to the h.d. and reconverted it back to .mpeg just fine. In fact it is much smoother looking than the original avi.
