Adobe Lightroom Classic AI Denoise compatible and not compatible format from same Canon 5D MKIV Camera RAW .CR2 files? Why?

[Mark Keefer]

I have posed this question in the Adobe Community website also. Is it a bug? So far, unresolved. I will update if there is a resolution.

I am using the New Lightroom CC Version 12.3 with AI denoise. (Up to date according to Creative Cloud Desktop) RAW Photos I have imported recently from my Canon 5D MK IV this year (2023) RAW .CR2 files can use the AI denoise, no issue. Photos I imported last year (2022) from the same 5D MK IV camera with the same firmware and RAW .CR2 files get a the are not compatible. The only thing I can think of is these were imported with a previous version of Lightroom CC. Will I need to re-import the images with the newest Lightroom CC or is there some other issue?  These are RAW files from the same camera. I am using a brand-new Window 11 Home Dell Alienware Laptop. Latest Windows 11, everything is up to date as far as software and drivers.

I just noticed at looking at the two photo sizes, the compatible photos is LARGE RAW Format...The file that is incompatible is MEDIUM RAW format.

Can't help, I am still on last standalone version of Lightroom:) Have to work around to process Sony100RX6.

Just got the scoop from the Adobe support forum. At this time only the Canon Large RAW are supported by AI denoise. The Medium RAW and Small RAW formats are not currently supported.  Good to know moving forward.
