Recently I sent my laptop to apple mainetenance to repair after the hard disk failure. then I sent the failed HD to a guy who extracted all my files including videos, but there's some video I cannot open, I think they are corrupted. for example when I try to open one .mov file with quicktime the attached error message appears. is there a tool to fix or repair corrupted video files ?
I did not find the right solution from the internet
