Canon EOS R6 Mark II - video only appeared as DAT file

[Rnav00]

Hi all, 

I had a video shoot and my second cameraman used a Canon EOS R6 Mark II. 

After the shoot, I noticed that one very important file only appeared as a DAT file weighing 0 bytes. Turns out the cameraman replaced batteries right after taking that shot, so I assume he either took out the battery without cutting or without turning off the camera (?). Can't know for sure what happened there. He was only recording to one card. 

This shot is extremely valuable. Is there anything that can be done to recover it? I'm desperate. 

Any advice would be appreciated! Thank you

Greetings,

Your description of the B-Cam users actions could certainly corrupt a video file leaving you with a .DAT 0 kb file.  Try working with a copy and see if you can convert it to .mp4.  

You can also try various recovery software.  PhotoRec is one.  Others may have suggestions as well.  Wishing you luck.  🤞

Does it play back in the camera?

No 😕 I can't see it in the camera.
