I'll freely admit to being a complete novice when it comes to video files - which may be obvious with the question...
At a track day I did recently, the Atom I was driving had an video to record it, but I was told the file was corrupted when it was checked after the drive.
I was recommended to use DivFix to repair it, but that only seems to be for AVI files and this one is an MP4...
So question really is - is there anything similar that may rescue an MP4 file?
