How to save HDR screenshots with OBS on Windows?

[Ihmemies]

Hello,

I understood OBS would save screenshots as JXR if everything is setup correctly. I am trying to capture HDR screenshots from Cyberpunk. The video preview on OBS displays HDR correctly as in not washed out, but when I take screenshots they get saved as washed out JPG's instead.

What kind of magic is required for OBS to save the screenshots as JXR so the HDR data from the image is saved correctly too? Some kind of algorithm deduces this based on variables I do not understand, this is not a manually editable setting.

Is there a list of prerequisites the OBS requires so the saving screenshots as JXR with HDR data works? Thanks.

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

Hello,

sorry. Here is a log file. https://obsproject.com/logs/dveHC6AH17OlSA38

I capture screenshot with a hotkey, shift-f12. There is no explicit talk about HDR I noticed, but switching the video formats to these made the picture look the same in OBS and in game (but not in screenshots).

10:18:09.563: video settings reset:
10:18:09.563: base resolution: 3840x2160
10:18:09.563: output resolution: 3840x2160
10:18:09.563: downscale filter: Bicubic

Surely, according to: https://learn.microsoft.com/en-us/windows/win32/api/dxgiformat/ne-dxgiformat-dxgi_format , the source ("BufferDesc.Format: 24") is 10-bit texture or DXGI_FORMAT_R10G10B10A2_UNORM

Can you right-click over the Game Capture source in the Sources pane and select the action "Screenshot (Source)"?
