Sure, here's the transcode log from the stream I just tried:

@gnattu @nyanmisaka - Any ideas?
RE: Green tint on some movies - scdouglas - 2024-09-26
Just checking to see if anyone had taken a look at this issue. I know it's probably not super high up on the list, but I just wanted to bump it and see if anyone had any ideas.

We can't tell if that is correct unless we can get the sample video. Can you make a 30s crop so that we can see if it is our tone mapping really wrong or is it something else.

Apologies for the delay. Here's the 30s recording where you can see how some seems exhibit the green tint really bad and others don't have it seemingly at all. I can recreate this across multiple movie files in any number of scenes as well so it isn't limited to just one or two files.

......I don't see an issue with the clip in question.

Yep that would make sense because Google Drive has compressed it into oblivion. In order to make sure it was better represented I got a new one taken on my phone so hopefully that's a bit better. It's super obvious in person and you can definitely see the color shift in the video once the clouds come up. This phenomenon appears throughout movies (so far I believe every single one is HDR) usually in darker scenes, I see it much more pronounced in shadows. Again this is on Shield TVs as well as the two OLED screens in my house.

What I meant is that you need to get the source file, make a 30s cut of that source file, so that we can test the tonemap on our own machine and see it with out own monitor, not looking at your recordings which is not helpful at all.

My bad, not the most technically literate when it comes to this stuff. I think to my eye the clip looks a lot less green than my recording of the issue and how it looks when being streamed over jellyfin.

Well it's weird. It does not look green on my machine, does this image look green to you on your OLED display?
