Hi!

There is any way to genearet metadata file to the x265 HDR10+ encoding?

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/c...hdr10-info

Don't know of an automated way to generate the metadata automatically.

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-h...explained/ for a basic explanation.
(+ https://www.dolby.com/us/en/technologies...epaper.pdf, + https://www.cnet.com/news/all-about-hlg-...r-your-tv/)

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...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?

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
