Camera froze while recording, can I repair the file?

[agfx]

Hi guys. I was recording with a Canon 50D and the camera suddenly froze, couldn't do anything but pull batteries. So on the card there's the movie file but I can't open it. It's a good 3gb file recorded which I am hoping I can retrieve and use, is there anyway to do that? Or that file is a goner?

Thanks!

Perhaps.  Were you recording MOV, RAW, or MLV?

For mov file maybe this can help.

They are MOV files. I tried that tool from the link but it didn't repair

I wrote a post about recovering h264 .mov from CF or SD cards

battery died on my 5D2 before it could write the header, in the end saved a 4 GB h264.mov
and save the documentary
