Metadata

[ItsMe]

Hi!

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

[Selur]

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?

[Selur]

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+.
