user12392: if I have a video file that is in .mov format, but the header has been overwritten, is there a way to scan the file to find the keyframes and somehow extract  them?

user1871: Try running the file through recover_mp4_to_h264, assuming video codec is H.264. You will need to supply a good reference file i.e. with valid header, of the same type as the damaged one.
