.... as per the subject.

It's embedded in the video track. It leaves it alone which is to say it's included.

OK, thank you.

If I had a TV which supported HDR10+ (I don't so this is all hypothetical), it would display with the HDR10+ metadata without any additional processing beyond the initial rip by MakeMKV?

Yes, the metadata is self contained in the original HEVC stream.

Once you've ripped a DV or HDR10+ disc, and you wanna Handbrake it to a smaller size, how do you get the DV/HDR10+ layer to copy over to the new file?

Handbrake by itself can't do it all..
You need to extract both HDR10+ and DV (converted to profile 8 ), then feed them to x265.

I don't know if Handbrake supports custom options for x265.
For HDR10+ you need: https://x265.readthedocs.io/en/master/c ... hdr10-info
And for DV: https://x265.readthedocs.io/en/master/c ... vision-rpu

Do you think if you ever had time and it interested you, that you could make a tool/add it to yours to extract + insert HDR10+ metadata into an HEVC stream like your tool and others we have for DV/RPU metadata? Your tool already extracts HDR10+ to convert to DV IIRC, so just the insert back as HDR10+ metadata part?

Eventually, I just have no way to test anything HDR10+ related..
The process would be the same as for Dolby Vision, but I need to refactor things first.

You're the best

This is now in the newly renamed "hdr10plus_tool" (yes very original).
See here: https://github.com/quietvoid/hdr10plus_ ... /tag/1.0.0

Since I don't have an HDR10+ display, this needs testing.

Awesome, thanks

I'll test it out and let you know how it goes as soon as I can, thanks again.

Hey, played around with it - does not appear to be working right unfortunately (or maybe user error?).

I took the HDR10+ metadata from the first 5 mins of WW84 and exported to json and then applied it to the first 5 minutes of Annihilation's HDR10 only BL stream. Mediainfo does report it as HDR10+ and it kicks in HDR10+ mode on my Hisense - but I am noticing no scene changing/flashing going at all going on - which should be noticeable given the mismatched input files. It's apparently just playing in HDR10 only, but while being reported as/in HDR10+ mode - with none of metadata actually being used.

Now, I did get this error when making the video file with the tool, but I assumed it wasn't discarding all the metadata, just at the very end of the video - I should still have metadata/scene changing going on at the start/rest of the video.



Here is the json that was originally extracted along with the resulting file that was made if you wanna take peek at them: https://mega.nz/file/sbol0KQI#snrJiB6QC ... 8-ETxbGkH8

Normally if the TV switches to HDR10+, the metadata should be used.
To me that makes it work.

I don't know if it would necessarily be flashing, though.
Depends on the metadata and if the video is brighter than your TV can display without tonemapping.

I know of this test video for HDR10+, if you want to try: http://ff.de/hdr10plus-metadata-test/
That should be showing a noticeable change.

In the meantime I might try using your JSON and turning it into Dolby Vision to see if it flashes for me.
edit: I'm seeing some slight changes around 0:55, 1:45, and 4:24. That's pretty much it.

Yes, that's showing what I was looking for, however...

change at 0:55 confirmed - it's subtle as hell and hard to see - I could only notice out of the entire scene the top part of the inside of the metal door/doorframe/whatever, reflection or something got dimmer. I was expecting an overall scene brighter/dimmer effect. I couldn't notice anything at the other two times.

So apologies, and thanks again
