Recover_mp4 Error: Unsupported video format

[DChosid]

I'm trying to recover a corrupted mp4 file. The recording unit was disconnected prior to the end of writing. Using Recover_mp4.exe, I entered "recover_mp4.exe good.mp4 --analyze" and recieve the following:

Cannot find 'avcC' atom (AVCDecoderConfigurationRecord) or
Cannot find 'hvcC' atom (HEVCDecoderConfigurationRecord) in 'good.mp4'
Be sure your file is MP4/MOV with the codec MPEG-4 part 10 (AVC/H.264) or
MPEG-4 part 15 (HEVC/H.265).
This program does not support video format 'mp4v'.

Mpeg-4 visual is associated with mpeg-4 part 2, typically Xvid and Divx.

It looks as if the program you're trying to use is intended for usage with mpeg-4 part 10, typically AVC/ H.264 video
and, apparently, HEVC

If the file is not too big, you're welcome to post the whole file and somebody will investigate further

Thanks. Here is the good file.

and the bad. I have more like these so I'm interested in the solution itself.

Try this to repair your files, I was able to get a result after
feeding it the good and the bad you provided.

Ellinorwilliam, thank you for the suggestion. I followed the advice of davexnet using the Video-Repair-Tool with good results. (Thanks davexnet and sorry I didn't thank you sooner). After using that software, I ended up with a working file but it still wasn't recognized by Premiere. I then used Handbrake to convert it to a new mp4 and that seemed to be acceptable to Premiere (whatever).

Anyway, thanks again folks. You saved a bunch of important underwater research video.

Btw, recover_mp4 is not free anymore, from what I've gathered. Here, https://www.videohelp.com/software/recover-mp4-to-h264 leads to http://slydiman.me/eng/mmedia/recover_mp4.htm website, and on his website, he says that the tool is now updated, all online, and has moved to https://restore.media/ website. Perhaps they own the service now
