I have some corrupt MP4 and MOV files that I'd like to try to repair. I've tried converting it in VLC and also in LosslessCut but they still won't play, and I've tried playing them in various players including VLC with the 'automatically fix broken videos' option selected to always and it still doesn't play. I've downloaded a few video repair tools but apart from one they all only work with AVI files, and the one that does accept MP4 files just says there was no problem found. I was close to giving up however fix.video does manage to repair the videos, the only problem is that they want $6 for each video which seems like a lot. Can anyone please recommend an alternative to try? Preferably free would be great, thank you!
Edit: Untrunc kinda recovered the video but the frame rate was kinda weird and it ran very slowly, maybe I can fix that
