[Video files recovered but unreadable]

I need some help:

 

• I took my SD Card from my camera and inserted it into a reader to transfer the files to my desktop
• It started transferring but then displayed an error saying no file existed.  No transfer occured.
• I couldnt read it in any computer, so I used CHKDSK to fix the boot file
• I used Revuva to deep scan and recover the files (mostly pictures and videos)
• The pictures are viewable so the recovery went well
• The video's were all labelled excellent and recovered as .mov files

 

But when I try to play them on VLC or QT, i get a message that the file is not recognized.

 

What am I doing wrong or what can I do to fix this? I would upload a file but they are too big to post here.
