4k HDR transcoding overblown colors

[mjeshurun]

Hello everyone,

I'm running Jellyfin 10.10.0, and I have an Intel Core i7-10700 CPU with UHD graphics 630.

When I'm trying to play 4k HDR content on devices that require the video to transcode, I am getting a picture with overblown colors. Please see attached screenshot.

   

I tried switching the tone mapping mode to RGB (as suggested on the Jellyfin Transcoding setup page), but that didn't help.

Does anyone have any suggestions how to fix this?

This is hard to answer without getting a small crop of the source video for testing.

But my question is the server really doing tone mapping? And did you touch other tonemap settings?

An ffmpeg log for this transcode could be helpful.
