Metadata - ItsMe - 09.01.2019
Hi!
There is any way to genearet metadata file to the x265 HDR10+ encoding?
RE: Metadata - Selur - 09.01.2019
You can add the dynamic HDR-10 data under "Signaling->Visual Usability Information->Dynamic HDR-10 data", but Hybrid has no way to generate such data.
see: https://x265.readthedocs.io/en/default/cli.html?highlight=dynamic#cmdoption-dhdr10-info
Don't know of an automated way to generate the metadata automatically.

Quote:Do you any infos how can i use these options, and what is doing exactly?Like with HDR-10+, Dolby Vision (https://www.dolby.com/us/en/brands/dolby-vision.html) is another way to save scene/image based HDR meta data.
HDR10 has one set of static meta data for the whole movie.
HDR10+ scene/image dynamic meta data. (each scene/image can have different HDR meta data)
Dolby Vision same as HDR10+, but defined by Dolby.
HLG static HDR meta data for the whole movie which is compatible to SDR but usually not that 'impressive/contrast rich' as HDR10.
See: https://www.cnet.com/news/dolby-vision-hdr10-advanced-hdr-and-hlg-hdr-formats-explained/ for a basic explanation.

So about the options, for Dolby Vision:
'--dolby-vision-profile' sets the Dolby Vision Profile the output should be compatible with, see: https://www.dolby.com/us/en/technologies/dolby-vision/dolby-vision-profiles-levels.pdf (note that only level 5 is currently supported)
'--dolby-vision-rpu' sets the Reference Processing Unit meta data specified.

Ok.
How can we extract the metadata from the source and, crate the file for the x265?
RE: Metadata - Selur - 09.01.2019
Sorry, no clue. Iirc there was a discussion about it over at doom9s (see: https://forum.doom9.org/showthread.php?t=174954).
https://forum.doom9.org/showthread.php?t=175947 might also be interesting in regard to HDR-10+.

hdr10plus metadata can be extracted from two systems.
ColorFront Transcoder, Davinci resolve.

How can we do this with Davinci Resolve?
I have Davinci Resolve Studio 15.2.2 on my MAC
