Help with Corrupted MP4 Video File

[jabetha]

I was recording video on my r/c plane when I crashed into the water. The camera became submerged and stopped working. I would REALLY like to recover the final 64 MB video it was recording prior to going into the water, but the file won't play. I am going to attach the crash video to this message and attach another 'good' video shot from the same camera earlier in the day for reference. Please note that I have truncated the bulk of data following MDAT in the file(s) using a hex editor to make the files a reasonable size.

Any help and/or guidance would be GREATLY appreciated!

Thanks in advance...

p.s. I tried moving all of the data following MDAT in the 'corrupted' file to the area following MDAT in the 'good' file but that just created a viewable empty video of the length of the original 'good' file.

crash.mp4

Here is the good video file shot with the same camera of a comparable length to the corrupted one. Again, I truncated the majority of data following MDAT using a hex editor.

Thanks again...
