Corrupted MP4 from GoPro. Repairable?

[Harabec]

First off thanks for reading my post. A friend recently recorded an important race with his gopro and everything seemed to go well. When he got home and copied the file to his computer, it froze every time he tried to open it. I've seen gopro batteries die mid-recording before so we popped the memory card back into the camera to see if a 'fix' mode would come up like they usually do, but nothing. I took it upon myself to try to figure out how to save this file but I've had no luck. I've reencoded it with VLC, I've tried ffmpeg but get errors, I even tried following the instructions here which gave me the best results so far - a video that would actually play in VLC but it's almost unwatchable. It stutters all over the place, has a wonky framerate, unsynced audio, and has lots of weird blocking on screen when there is movement.

Would anyone with a lot more experience than me be able to look at this video and see if it is salvageable? It doesn't have to be perfect, but if its watchable that would be amazing. I'm pretty sure the original resolution is 1920x1080 but i'm not positive if he had it set to 30fps or 60fps. Here is a link to the original MP4 that came off the gopro. Thank you for the help!

You can alsy try https://www.videohelp.com/tools/recover-mp4-to-h264 . It's a command line tool that tries to repair the headers.

Make a copy of the original mp4 before working on it.

I tried using that software and it gives me the message

"Cannot find 'avcC' atom (AVCDecoderConfigurationRecord) in 'copy.MP4' Be sure your file is MP4/MOV with the codec MPEG-4 part 10 (AVC/H.264)."

I know its a mp4 file, even if it is corrupted, as the one recovery software I used that sort of helped gave me a mp4 that vlc would launch.

My mistake on the last post, that error was because I was trying to create the -avcc file from the corrupted file, not a good source video. I tried it out with a good source video and am still getting a lot of corruption in the video I get out of it. Any ideas?
