I've had this happen before. What you may want to try first is seeing if you can open it in vlc. It may take some time to load but it may work. I loaded an mp4 with the same problem and then used vlc transcoder to export it to mpeg 2 and then aac audio. I was able to then re-merge the files and recover the livestream. The other way is to use the digital rebellion pro maintenance tools media salvage and recover it that way.

It might work...
1 - look for video repair tool (the free version allows you to recover only 50% of the analyzed file - Video Repair Tool
2 - create or recover a file of the same features and functioning
3 - duplicates the mp4 file corrupt, and rename them: file1.mp4, file2.mp4
4 - Open a command promp
5 - type "copy / B + file1.mp4 file2.mp4 corrupted.mp4" (so it creates a unique file and double that corrupt;-))
6 - Open Video Repair Tool
7 - in the "Choose movie" put the resulting file "corrupted.mp4"
8 - In the "Choose Reference movie" put the functioning file
9 - Scan and good luck

I sucessfully used this tool: http://grauonline.de/cms2/

It has recovered 100% of the files ever lost in crashes or general power failure during an event.

It can repair almost any file.

Another tip: choose new file every.. This way you won't loose everything at once.

This past Sunday May 16, 2021, I also was doing a live recording. Towards the end of the show, everything froze-vmix, my computer etc. Running a RTX 2070 super, Intel i7-10, 16 RAM. Recording in mp4. Now the file will not open with VLC. Tried the suggested Grau software demo, but go a lot of artifacting. Price of the their software is 99 euros. Steep for something that might work or not. Anybody come up with a better way to recover corrupted mp4's? Please help. Thank you.

Found somebody in FACEBOOK pages that gave me a solution. 40 dollars for a year usage of this software. It did the job well enough to have saved my butt.

Did you try a ffmpeg re-index?

ffmpeg -i inputfile.mp4 -codec copy -movflags +faststart outputfile.mp4
