Denoise error message " not compatible with this file format"

[jimbo9058]

This post started out as a question about the error message that I get when I try to use DENOISE on my raw files.  The error message says: "Denoise is not currently compatible with this photo format".  I then attached 2 photos (a CR2 and a DNG) to the post and hit the POST button.

The post won't go through because the 2 photos I attached are flagged as non-raw photos (see the error message below).  What in the world is going on ??

Are the "RAW" files mRAW or sRAW?

They're not supported by Denoise, because they're already demosaiced.

(And you can't attach RAW or DNG files to this forum, because they aren't web-viewable image formats. You'd need to host them online somewhere and post a link)

The CR2 file is mRAW and was used to create the -HDR.DNG file. Is that
why they're not compatible? Will I run into the same problem using cRAW on
my Canon EOS R?

If so, PLEASE fix this compatability issue PRONTO.

At least on my Canon R6 MII, sRAW is supported; it is truly raw. That said, I still never use it. 

If you want this to all work, just set the camera for raws, not variants of a raw, which may not be really raw data (linear DNG isn't):

Edit: that should read C-raw not S-Raw.

"At least on my Canon R6 MII, sRAW is supported; it is truly raw. "

sRAW on an R6 Mk II? Sure about that? It's got C-RAW (which is a proper compressed but not demosaiced RAW format - I use Denoise on my R5's C-RAW files all the time) - but sRAW?

From Canon.co.uk's R6 Mk II page - no mention of sRAW here:

Sorry; indeed it should be C-raw. I only made one test last week for another post and that flavor worked. Then I immediately reset back to raw. 

[Keith Reeder]

Great - thanks for clarifying.

Personally, I've yet to find a downside to using C-RAW on my R5 or R7, so it's selected 100% of the time.

I'm not finding much data on the differences in the two formats, so I may have to run a test (unlike the video below, a real controlled test*)

My shooting isn't such that I need to capture a massive amount of images on the dual cards, so I was just being conservative and using raw vs. C-Raw, but the latter appears to have some advantages besides just size. The video states one is 12-bit, the other 14-bit, but that shouldn't make a difference with well (optimally) exposed images.

Yeah, I'm a wildlife/motor sport/aircraft photographer, and I can easily generate a four-figure count of files by the end of a session, so C-RAW has been a Godsend for me.

It's not that I can't carry more cards (I've always got plenty), but if I don't need to, it's a no-brainer not to.

"Will I run into the same problem using cRAW on my Canon EOS R?"

No, Canon's C-RAW contains mosaic sensor data that Denoise will process.  (I downloaded some sample C-RAWs to verify.)

It's not a "compatibility issue" Jimbo, it's by design - Denoise currently needs files it can demosaic, in order to work properly.

Adobe is on record (and note - you're talking to other users here) as being open to expanding the application of Denoise to other formats, but as of  right now:

"Denoise is currently supported only for Bayer and X-Trans mosaic raw files, but we’re looking into ways to support other photo formats in the future."
