Dolby Vision now possible through MP4 Mux.

Can I ask how you remove HDR10+ because I need to do that on some files.

You can try this: https://gist.github.com/quietvoid/175d7 ... 9eb1bd2c38
It's based on yusesope's script.

Looks like what I need - can you tell me how I use the script though? I've installed python but I'm not sure how to use it.

You need to demux the video first, and then run the script on the HEVC file.
example: python hdr10plus_remove.py -i video.hevc -o processed_file.hevc

When I convert HDR10+ do DoVi, do I need to change something in generator_example.json or can I leave it as it is?

You should adjust the JSON. Probably removing the level2 list as well as specifying proper level6 metadata.

Thanks for that. Is there an idiots guide on HDR10+ to DV conversion?

I wrote up how this idiot does it here:

https://www.avsforum.com/threads/author ... t-60952335

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Turn HDR10+ metadata into Dolby Vision metadata**
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Command 1: 'hdr10plus_tool extract Video.hevc -o Metadata.json' (Extracts HDR10+ metadata and saves to .json file)

>>Next commands go through Dovi_Tool and v0.5.0 minimum required<<<
Command 2: 'dovi_tool generate -j Extra.json --hdr10plus-json Metadata.json --rpu-out RPUPlus.bin' (combines metadata from edited 'Extra.json' - template is below and you need to do one for every title specifically - and metadata from extracted 'Metadata.json' and combines+converts them into p8 RPU metadata format)

Command 3: 'dovi_tool.exe inject-rpu --input Video.hevc --rpu-in RPUPlus.bin' (Injects HDR10+ generated RPU metadata into HEVC stream turning it into single layer Dolby Vision 8 stream)
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Blank Template for 'Extra.json'

1- extract HDR10+ into a json

Code: Select all

hdr10plus_parser.exe -i X:\HDR10+.hevc -o X:\HDR10+.json

2- create a json with L6 metadata (static HDR metadata: match your source)

Code: Select all

{
    "length": 0,
    "level6": {
        "max_display_mastering_luminance": 1000,
        "min_display_mastering_luminance": 50,
        "max_content_light_level": 0,
        "max_frame_average_light_level": 0
    }
}

3- generate DV metadata

Code: Select all

dovi_tool.exe generate --hdr10plus-json X:\HDR10+.json --json X:\L6.json --rpu-out X:\DVrpu.bin

4- inject DV metadata

Code: Select all

dovi_tool.exe inject-rpu -i X:\HDR10+.hevc --rpu-in X:\DVrpu.bin

Brilliant, could you give me a link to the current dovi_tool.exe? Thanks very much

Sorry to be an absolute pain, could you also point me to the HDR10plus_parser.exe. Thanks!!

Amazing help, thanks so much. In a couple of days I'm going to be asking you about injecting the MADVR created metadata as DV!!

Do you know how I can enter a "min_display_mastering_luminance" vlaue of 0.005? It doesn't seem to like that - it only want whole numbers. I've used 0 which I think must be close enough!

Ah OK - it says 50, am I reading it wrong?
