I expected as much. FFmpeg does not have the ability to recover MP4
files without the “MOOV atom”. You might find software capable of
extracting something from a damaged file and possibly a valid file from
the same origin, but I do not know any: if you find, please let me know.

Please avoid top-posting. Look how the people who post frequently here

Restore a damaged (truncated) mp4, m4v, mov, 3gp video. Provided you
have a similar not broken video. And some luck. Also works the same way
with audio like m4a.

You need:

Another video file (taken from the same camera/app) which isn't broken
Libav 12
Basic ability to use a command line
