PL9 AppleRAW images error messages when trying to export

New PL9 user (had been PL users since PL6. Using MacBook Pro M1 32gb ram, 2TB internal SSD under Mac OS Sequoia 15.6.2 and and Apple iPhone 15 Pro.

With new PL9 stated support for iPhone ProRaw and HEIF, I cannot edit, process and/or denoise and then export the iPhone DNG or HEIF images back out to a folder. Receive the error message in attached window. The image files are coming from a folder of images imported directly from my iPhone and not thru any other image editing software.

Wondering if thePL9 release is not a finished product. My issues seem to be in conflict with what DXo says new PL9 can now support.

Hello! Are you trying to edit single-frame DNG RAW files or multi-frame linear DNG ProRaw files? PL9 enables editing of the latter but not the former. Also, are you trying to export as linear DNG files? That doesn’t seem to be possible at the moment for either ProRaw or HEIC files. I get a similar error code on the export page (Win 11).

I don’t understand the difference between single frame and multi-frame files. Yes I am trying to export the Apple ProRaw file(s) which are DNG back out as a linear DNG.

Have been wondering is PL9 is a work in progress and not yet a finished product.

The PL9 user guide indicates that export to linear DNG should be possible for both HEIC and ProRaw formats. That’s not happening at the moment. So, you seem to have uncovered a good example of something left undone. Nice catch! Perhaps a good idea to bring this to DxO’s attention.

update 9/6/25: I’ve submitted a request to DxO support that includes a screenshot of the error message. Thanks for alerting us to this problem.

Any chance you might be able to share a file for others to test?

Thanks for your response and for submitting the info to DXo.

Also, I don’t understand the difference between ā€œsingle frameā€ and ā€˜multi-frameā€ - what does that refer to?

You refer to ā€œAppleRawā€ in the title of your thread. Standard convention is that RAW files, by definition, must contain un-demosaiced sensor data (unprocessed). Apple ProRaw files are not RAW files as the sensor data has been demosaiced. Apple often refers to these files as RAW, but that is mostly market-speak.

Third-party phone camera apps like ProCamera, CameraPixels, Halide, etc. can produce single-frame captures, true, unprocessed RAW DNG files, where the sensor data is un-demosaiced. These are functionally identical to the RAW files produced by ā€œrealā€ cameras and can be edited in similar fashion. At one time DxO PL supported these single-frame RAW DNG files from the latest smartphones, but no longer. Curiously, these older DNG files, e.g., from an iPhone 7, can still be opened and edited in DxO PL9.

ProRaw files, on the other hand, are multi-frame captures that are computationally merged and processed in-phone. They are linear DNG files, meaning that they are partially processed, and that the sensor data has been demosaiced. Linear DNG files retain a lot of flexibility for photo editing, and contain extensive metadata that devices and programs use to interpret and display images properly.

Thanks for the detailed explanation. Since why I bought PL9 cannot be done I am withdrawing from this thread. No further responses necessary.
