Denoise AI not working with my .CR2 files

Hi, 

 

Camera: 5D Mk 4 

Adobe software: Lighroom Classic (updated to the latest version)

 

I was really exited to try this feature out but im getting the following message when trying to use this tool:

"Denoise is not currently compatible with this photo format" 

 

My understanding was that it would work with .CR2 files? is there any way i can fix this?

 

Things ive tried:

- Restarting my computer

- Re-importing images back into LR 

 

Please do let me know if there is a fix for this. I have attached my photo raw details.

The linked steps say, "Then go to the Metadata Panel and set the view mode to DNG, what does it say in the Mosaic Data field? If the field says "yes" Denoise should work. If it says "no" it means that your shooting format was not compatible."

 

Your screenshot shows:

 

When Mosaic Data says Yes, that means the file contains unprocessed sensor data (a "true" raw).

 

So the file is a processed raw, not a true raw.  The Exiftool utility confirms they're in sraw or mraw format:

"I don't see anything in the EXIF data in RawDigger that explains this"

 

It's buried deep:

 

Looking at the reduced pixel dimensions also gives a clue, as @Sean McCormack pointed out, if you know the full dimensions of the camera.

 

LR makes this much harder on users than it needs to be:

Were the raw photos shot in mraw or sraw format?  These are partially processed raws (reduced size), and Denoise only handles unprocessed raws.  If you're not sure, see here for how to tell:

See the camera manual for how to turn off mraw/sraw.

I can open them in, and they look pretty awful :

 

I can convert them to DNG. 

Neither allows the use of Denoise. I don't see anything in the EXIF data in RawDigger that explains this, but EXIF is often over my head. 

Can you reset your Canon so it certainly shoots a raw without any possible exotic setting and try again?

This is a true Canon CR2 raw, not a compressed or cRAW as they call it? 

Can you upload one of these raws to something like Dropbox so we can examine it?

What's the machine? More specifically the GPU memory? Denoise needs a lot of it.

More specifically here's the relevant section:

 

Need for speed. Denoise is by far the most advanced of the three Enhance features and makes very intensive use of the GPU. For best performance, use a GPU with a large amount of memory, ideally at least 8 GB. On macOS, prefer an Apple silicon machine with lots of memory. On Windows, use GPUs with ML acceleration hardware, such as NVIDIA RTX with TensorCores. A faster GPU means faster results.
