P: Export window doesn't remember previous setting for JPEG XL Bit Depth

[johnrellis]

When Export's Image Format is set to JPEG XL, the Export window doesn't remember that the previous setting of Bit Depth was 16 bits.  

Tested on LR 13.5.1 / Windows 11, Mac OS 14.6.1:

1. Reset LR's preferences.

2. Select a raw file and do File > Export.

3. In File Settings, set Image Format to JPEG XL and Bit Depth to 16 bits:

4. Click Done. 

5. Do File > Export, and observe that Bit Depth has been reset to 8 bits/component (incorrect):

6. Change Bit Depth to 16 bits/component and click Export.

7. Do File > Export and observe that Bit Depth has again been reset to 8 bits/component (incorrect).  

8. Change Bit Depth to 16 and click Export.

9. Do File > Export With Previous and observe that file size of the export from step 8 is quite a bit larger than that from this step.  Use the "jxlinfo" command (on Mac, "sudo port install libjxl") to observe that the step 8 .jxl is 16-bit while the step 9.jxl is 8-bit (incorrect).

Updating status - adding bug number

Hello since I last updated LR classic there has been an annoying bug when exporting PNG files. Every time I select 16 bit instead of 8 bit it automatically reverts back to 8 bit after I've exported the file. It's never done this before until the latest firmware update. Up until now it's always stayed on what I previously selected. Does anyone have a fix for this issue?

Very similar symptoms with exporting JPEG XL were acknowledged as a bug by Adobe in LR 13.5.1. 

As a workaround, define an export preset with Image Format: PNG and Bit Depth: 16 and export with that.  I just verified that works on my LR 14.0.1.

Moderators, @Rikk Flohr: Photography, please merge with this bug report

https://community.adobe.com/t5/lightroom-classic-bugs/p-export-window-doesn-t-remember-previous-sett... 

and change the title to:

"P: Export window doesn't remember previous setting for JPEG XL or PNG Bit Depth"

I tested all the file formats, and the bug only occurs with JPEG XL and PNG.

I always save a jpeg and 16 bit PNG with my best photos so I'm constantly switching from different formats, so defining and export preset won't do much for me at this stage. Hopefully Adobe fixes it soon as it's a real pain. Thanks for your help 👌

"I always save a jpeg and 16 bit PNG with my best photos so I'm constantly switching from different formats, so defining and export preset won't do much for me at this stage."

Perhaps I'm misunderstanding. After defining the preset "16-bit PNG",  whenever you want to export a photo as 16-bit PNG, you simply right-click the photo and do Export > 16-bit PNG:

It's faster than opening the Export settings window and choosing the image format and bit depth.

Ok I wasn't aware of this. I'll try it when I get home. There's probably many shortcuts I'm unaware of. Thanks 😉

User presets is grayed out on mine for some reason, won't let me select anything.

It's ok I figured out how to set it up. This will save me heaps of time BIG thank you 👍👍😁😁😁

Good, confirmed that LR 14.1 remembers the Bit Depth setting for both JPEG XL and PNG.
