does Lightroom Classic support compact raw files?

If you are referring to the Canon C-RAW format, the answer is yes. C-RAW format uses a lossy-compression meaning that you lose original information in the image. I do not see the benefit of C-RAW as an original image file type.

I have read that the loss in image quality is negligible. I have just bought a Canon R6 mk2 which offers the cRAW. This camera can take 40fps and does in camera focus stacking and has a "RAW burst" mode with "pre-shooting" - this means a half press of the shutter starts recording for about half a second (ie 20 frames at 40fps) and then continues when the shutter is fully pressed. You can then choose which frames from this to keep. These can very quickly fill an SD card.

It is good to have an option of a smaller file size (about half) with minimal loss of quality.

Lightroom Classic supports this file format, but you can’t use AI Denoise.

I have just used AI denoise on a cRAW file from the Canon R6 mk2 (with .CR3 suffix) - LrC v 13.2

So is a lossy JPEG straight from the Camera. The solution is to get a bigger SD card. a 1TB SDXC card is ~$100USD.

OK, it’s a little confusing with these formats. Apparently cRaw is still mosaiced, so Denoise works. I was thinking about sRaw which is not mosaiced anymore.

In my R5 I have used both RAW & cRAW. I see very little difference between the two. For most of my work I now use cRAW.

I have been using it for years. No perceptible loss in quality, and an advantage gained in shots per sec when shooting high speed burst.
LR DeNoise works just fine.

The buffer clears quicker too.
