P: Denoise unavailable on compressed DNGs

On all my compressed DNG files I am seeing "denoise is not currently compatible with this photo format"

Anyone else?

    Denoise is only compatible with Bayer and X-trans files. DNG uses Bayer, but Compressed DNG have already been demosaiced.

    Today's updates to Denoise allow for additional raw file formats. See: https://helpx.adobe.com/lightroom-classic/help/whats-new/2025.html#denoise

      Could you please update the app that we could use those functions with the medium comprassed raw format sony a7 iv?
      It is a very used format for wedding photographers.
      When will it come out? Thanks

      It's not as simple as that. Denoise doesn't work with any M or S raws from any camera. It has to be full resolution.

       

      Currently, Denoise can only work on mosaic raw files, Bayer or x-trans encoded. Downsampling a raw file means disrupting the Bayer/x-trans pattern, so downsampled files need to be pre-processed in camera, either by RGB-encoding them or some other special processing.

       

      Either way, what you're requesting is an extension of Denoise's basic functionality, so that it can also process RGB-encoded data. This may be (and probably is) on Adobe's future roadmap, but we're not there yet.

       

      EDIT - but Super Resolution should work.

          So even though I used Lightroom's "Lossy Compression" I will never be able to use this feature?

          I can't speak of the future.

           

          Now?

           

          HDR and Pano Merged DNG files have already been demosaiced. Therefore, they're not compatible with Denoise. Your Compressed DNG files at 8-bit are equally not compatible with Denoise.
