I have 1 mp4 file that is 7gig and I cannot get it to play on a Mac or Windows 10. I have tried to play it with VLC, WMP QuickTime. I have tried to convert it or run it through Handbrake. No Luck! I do not have the original VHS tape that was used to capture with mp4.
Can anyone help me out please?
Thank

How large is the file?
Did you run it through MediaInfo yet?

Time to get familiar with it.

What does it show as to the file contents?

I downloaded MediaInfo and "opened" the mp4 file in question and all I got was a General tab in the tree and the name and file size in the "tree"
I also opened a different mp4 file and it gave me 2 pages of info.

It's probably corrupted, data bad or lost. The header is definitely gone, but maybe more data. It's not a normal video file, and probably never will be again.

If you downloaded this, the download may have been incomplete.

Thanks LS. I tell everyone to keep their original tapes for this reason. I can't recover it for her because I only keep their files for about a month after I deliver their tapes back to them. Its impossible to determine where the corruption took place but I am 99% sure it was fine when I delivered it to her.
Thanks again.

Ffmpeg can sometimes recover stuff from files that have missing/corrupted bits (e.g .avi captures that stopped because of a crash and didn't finish writing properly) but if the start/header is gone that may not work.
