Recovered CRM files not displayed in Cinema RAW Development

[cinemastoreg]

Hello, I have a non-standard problem with *.CRM video files. I accidentally deleted them from my SSD on my computer. The files did not fit in the basket. I immediately ran a deleted file recovery program (tried different ones) and the files were quickly and completely recovered. But now these files are not displayed in Cinema RAW Development.

Who can help me? Any help on data file structure or anything. Thank you !

Can you get them from your backup?

[cinemastoreg]

No, I don't have a backup of this data. I think the problem is in the file structure, maybe some mark in the file or something.

You'll need to then explore data recovery options which could be quite expensive.

But do take a crucial lesson from all this.  Backups!

On my Mac, I use Time Machine which does hourly backups to a RAID 1 drive.  I then put smaller sets of files also in the cloud (Apple's cloud service).  And for files that are way too large for the cloud (photos and video), I copy to a removable drive each month to store at an offsite location.

For photos and video, I ultimately have four copies:

• One on the main data drive
• Two technically on the backup two-disk RAID 1 drive (1 file per disk)
• One offsite

Do you get an error or other message when you try to view the files?

You can take a hex editor and compare the first bytes in each file to see if you are missing anything.

No errors or messages. I also add screenshots.

Hello!

I'm having the same problem, Did you ever get the .CRM video files you were asking about to function properly?

thanks,

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
