MP4 video file from GoPro not working

[derrickR]

So I have a bunch of videos from my friends GoPro that I've been trying to fix but nothing has worked, so far they all say that it's severely corrupted. They all show an appropriate file size but when I try to play them they just show a black screen and the duration of the video on all my video players and when I go into the properties to look at the info the sections are all empty. If anyone can help me I would greatly appreciate it, thank you

Lets start with the basic question first: What program(s) are you using to try to access the MP4 files?

To play them I've used Quicktime, VLC, Gom player, WMP and MPC-HCx64 and all of them have the same result. to repair it I have tried Remo Repair MOV, SFWare Repair MOV, Yodot Mov Repair, and perl Binaries/Activeperl and they have all told me the file was too corrupted
