IIQ S files NOT exporting from lightroom

[isaacl76016202]

Hello,

I'm trying to export IIQ S RAW files shot with a Phase One 180 db and getting a "There was an unknown error." when I try and export (to JPEG, DNG, whatever) . Files are imported and processed fine. 

IIQ L files have always exported fine and still do (as have IIQ S in the past). 

what's going on? Do I need to use Capture One to use IIQ S files?? 

i'm on a MBP M2 Max with Sonoma 14.4.1 

LR Classic 14.1.1

Try turning off "use GPU for export". It's in the custom options in the "Use Graphics Processor"  preferences->performance. If that doesn't help, can you share one of the files that refuses to export? Also check if there are no weird characters in the filename or export path such as / ? ' " etc.

Thank Jao. Unfortunately that didn't work. I'm not super keen on sharing the files as they're family pictures.

Another little detail is that if I try and edit in>Photoshop, I get this error:

Could not open “CF012178.IIQ” because of a program error.

The only way I can currently get this is out is via "printing" to PDF in the print pane and then exporting in preview as jpeg, which is obviously far from ideal... 

Very odd. I wonder if LR is struggling with the lossy version of IIQ. It's never had a problem with the IIQ L  files - I've been using LR with those for years. 

Below is a description of the IIQ S files:

The lossy version of the RAW format provides higher compression than smaller file sizes and improved workflow:

• IIQ S is a smart compressed RAW file format which can be used in almost all applications where it provides a completely sufficient quality. In fact, smart compression is so good that it can be difficult to see the difference. However, there is a very small loss of data and, therefore, Phase One does not claim that IIQ S is completely lossless but only near-lossless.

Just shoot an image of a chair or something unidentifiable. I only asked because I could not quickly find sample files from this camera online. I can only find L raw version samples and they export fine on my M1 Max running Sequioa.

Trying to upload an innocuous image, but annoyingly, "The file type (.IIQ) is not supported." Any other way?

[Jao vdL]

The trick is to upload it on dropbox/OneDrive/iCloud drive or similar and post a link. The forum indeed does not allow raw files upload.

CF011960.IIQ

Let me know if that works. 

I think the answer here is that Adobe can't deal with the IIQ S compression / RAW container from Phase One, whereas it can with IIQ L.

Odd though that I can import the IIQ S files and edit, but not export or edit in PS.

I'm guessing there's proprietary bits that adobe can't touch there? not sure. So, annoyingly, I'd need to use Capture One for IIQ S and either convert to DNG (which is just another RAW container) or or just edit/keep in Capture One's ecosystem...

I get the same result. I can edit this photo all I want (which indicates the core rendering code works) but as soon as I try to export it says that an unknown error occured. This is likely a bug. Probably something about the metadata trips the export up.

Thanks man. by any chance do you know how I report this as a bug to Adobe?

[Jao vdL]

This forum is the mechanism. I think you can change this discussion into a bug or post as a new bug and refer to this thread. I also warned a adobe tech about this thread.

Hello,

I'm turning this into a bug post!

Please let me know if there's a timeline for fixing this error.
