Recova restores video file but media players can't read it

Hi there,

I'm trying to use Recova to recover deleted video from a SD card. Recova finds the files and restores them but for some reason no video player can play most of them. Originally I restored a lot of files in a batch and a few of the videos worked but most didn't. They were originally in mp4 format but when I open it in windows media player the message "Windows Media Player encountered a problem while playing the file." pops up. VLC player just shows a black screen with no audio even though the progress bar is moving. I tried converting it to MOV and WMV but that doesn't work. I tried restoring the videos one at a time as well but that didn't help either.

Suggestions?

It may be missing header information, etc. Maybe try to convert it in Avidemux (free/open source).

I just tried it. I imported the file to Avidemux but it only shows a green screen with no audio. Same with Adobe Premiere Pro.
