C200 .CRM Corrupt file? Anyway to Combine .DAT & .DMV?

[loggylunch]

Hey there,

Was recently shooting Canon Raw Light. Camera died whilst shooting, and the C200 did not combine the raw light data files for the actual video file. All I had on the memory card was a 1) .DAT fle and 2) a .DMV file.

Is there anyway possible to combine these or recover the video on them?? It seems like it should be a pretty simple fix/script to remedy.

I just had the same problem. Try puting the card back in the camera and watch media on the camera. It will come up with a question mark. When you try play the clip it should give you the option for recover the clip. 

This worked for me! Good luck. 

Alex.

That’s good that it’s working, I only had one corrupt file thankfully.

Is there an option to recover the .CRM film file without in camera recovery? The original SD card was formatted so I only have access to the .DAT & .DMV file on the computer. Any suggestions? Thanks!

Hi everyone,

Re-opening this thread, I have a few corrupted .CRM files that were shot on the C300 MK III. The original media card has been formatted so the in-camera repair solution isn’t an option. As Isabel, I’m looking for a software solution to fix these .CRM files. They won’t open in Premiere or the Canon RAW utility. Any information would be appreciated! Thank you!

Hello

Same problem, but the solution to put the card in the media session doesn't work for me...i recorded on the SD card on MP4 format/// so i can"t read the corrupted files on the media session, because the media session only read Raw files....any suggestion?

I managed to recover and fix a .crm canon raw light file, from a Canon C70, and recovered from an SD card, by using Claude to drive the mac terminal app to assess/fix the file.

- Recovered a .crm, as well as a .dat and .dmv file using Disk Drill.
- Crm file showed image preview, but didnt work in any video editor.
- Claude gave terminal commands to copy an image of the sd card
- then analysed the file in various ways via terminal
- analysed a 10 second clip, recorded in camera at the same settings as recovered clip, compared.
- adjusted clip internals to match
- bit of trial and error, but finally got a working file - audio and video work.

I've documented my Claude-driven process here - with Claude notes on things tried and scripts to use: https://gist.github.com/jeanpoole/54f1e923034cf973bd473bd846246e72
