--- Quote from: SamuriHL on April 20, 2023, 09:45:32 am ---What happens when a video has both HDR10+ and Dolby Vision? Does it just stick with the HDR10+ metadata to help with tone mapping and setting the tone curves? Or does it somehow use both? The reason I ask is I see both listed in the display when playing one so was unsure what, exactly it was doing. Looks fantastic either way just more curious how it works.

If HDR10+ tone mapping curves are present, it'll use those. Thats not a features supported from Dolby metadata yet. Dynamic scene brightness is used from either HDR10+ or DV, hopefully they wouldn't vastly disagree what the brightness is.
Note that there is no commercial content that ever supports both. Self-made content with copied metadata from other sources ... well no guarantees if they don't match.

That is absolutely untrue I'm afraid. There most DEFINITELY is commercial content that has both! I know, I have a bunch. Alien, Alita, etc etc. Hence the question. Whether they match, I couldn't tell you as I don't have HDR10+ support on my LG OLEDs.
EDIT: This is from 1917, as an example:
Video
ID : 1
ID in the original source medium : 4113 (0x1011)
Format : HEVC
Format/Info : High Efficiency Video Coding
Format profile : Main 10@L5.1@High

Fun, right?? :D

Hendrik, do you know if HDR10+ JSON Sidecar files are supported?

They are not, and will not be. Metadata needs to be in the video. Metadata in extra files is a tool for authoring, not for playback.

thanks
