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..staknhalo wrote: Fri Aug 27, 2021 1:08 pm 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?

You're the bestquietvoid wrote: Fri Aug 27, 2021 2:18 pmEventually, 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.
This is now in the newly renamed "hdr10plus_tool" (yes very original).staknhalo wrote: Fri Aug 27, 2021 1:08 pmDo 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?

Awesome, thanksquietvoid wrote: Sun Sep 05, 2021 9:36 pmThis is now in the newly renamed "hdr10plus_tool" (yes very original).

Since I don't have an HDR10+ display, this needs testing.
Hey, played around with it - does not appear to be working right unfortunately (or maybe user error?).quietvoid wrote: Sun Sep 05, 2021 9:36 pmThis is now in the newly renamed "hdr10plus_tool" (yes very original).

Normally if the TV switches to HDR10+, the metadata should be used.staknhalo wrote: Mon Sep 06, 2021 11:03 pmHey, 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.
Yes, that's showing what I was looking for, however...quietvoid wrote: Mon Sep 06, 2021 11:32 pmI 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.
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.quietvoid wrote: Mon Sep 06, 2021 11:32 pmedit: I'm seeing some slight changes around 0:55, 1:45, and 4:24. That's pretty much it
