Over-bright subtitles in HDR, but no GUI Peak luminance option

Even if you saw the option, it wouldn’t do anything. Same with ‘Adjust display HDR mode’ in Player settings. We need to remove that one.

Hi @mceron

Hopefully the issue is now addressed.

I’d appreciate it if you could test this and provide feedback before we potentially release this as an update to other users. To test this update:

  1. Login via the command line
  2. Run the following command to add the staging repository:
    echo 'deb http://apt.osmc.tv bullseye-devel main' | sudo tee /etc/apt/sources.list.d/osmc-devel.list
  3. Run the following commands to update: sudo apt-get update && sudo apt-get dist-upgrade && reboot
  4. Your system should have have received the update.

Please see if the issue is resolved.

I also recommend you remove /etc/apt/sources.list.d/osmc-devel.list after updating.

This will deactivate the staging repository. You can do so with the following command:
sudo rm /etc/apt/sources.list.d/osmc-devel.list.

Please note that we will automatically disable this update channel after 14 days on your device in case you forget to do so to ensure that your system reverts to the stable update channel.

Hi @grahamh !

Thanks a lot for adding this so quickly! I’m impressed.

I’ve updated following your instructions and I now have the setting to update luminance in PQ mode. I tested it and it does dim both my subtitles and also Kodi’s GUI when I’m watching an HDR movie.

I tested the same file with unmapped subtitles and it works very well.

I’ve decided to lower the setting from the default 40% to 20%. I still want to test this at night, I have a bright room. But I can confirm that the setting definitely works!

Am I right to assume that the GUI peak luminance in HDR PQ mode option affects all subtitles, tone-mapped and not tone-mapped subtitles? If I were to set it to 50% to make not tone-mapped subtitles look comfortable, then the tone-mapped subtitles would be too dark, right?

AFAIK Kodi doesn’t know whether a subtitle is tonemapped or not so I’m guessing you’re correct. But subtitling is a mystery to me. This feature should behave the same as on other platforms so if there’s an issue you might look on the Kodi forum.
