- I think max cll and max fall should also be specified for better color reproduction, but they should not be strictly necessary (afaik players should use mac cll 0 and max fall 1000 as fallback or use some auto tone magic).
- What might be a problem are the missing level&vbv settings. (especially since open gop is used) This is mainly for player compatibility not for color handling.
Other than that the settings should be fine.
Quote:I don't have a device that can play HDR10 or HDR10+, I want o buy one, but I want to know if with those commands will allow me to play play the video on compatible HDR10 device.Since I personally don't have any HDR10(+) compatible hardware either I would recommend to create a file but it on a usb stick and if there's an 'offline' shop selling such a monitor/tv ask them if they could playback the file for you. (or create a sample and share it with some other folks who have the necessary hardware to test)

Thank you for the replay!
I just wanted to make the encoder setting simple, but good for quality. I just used
--preset slower --profile main10 --crf 18.00--range limited --colorprim bt2020 --transfer smpte2084 --colormatrix bt2020nc --master-display "G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,50)" --hdr10 --hdr10-opt --dhdr10-info "E:\Other\Proiect\Windows APP\FastFlix\metadata2.json" --dhdr10-opt --output OUTPUTFILEI just want to let the encoder select the best level that is required for my video baste on the info from the video and the output of the video, also I read that open-gop is better for quality wish, source: https://streaminglearningcenter.com/arti...-know.html
The source of the video was: audio was passthrough all

Mastering display luminance : min: 0.0050 cd/m2, max: 1000 cd/m2And about VbV, I read that is useful to restrict bitrate in CRF Mode, to not go higher than a certain vbv-maxrate https://slhck.info/video/2017/03/01/rate-control.html
I'm trying to understand if is better to let it on unrestricted level so it can be selected automatically and without vbv.
But if vbv helps, how can I calculate to get --vbv-bufsize and --vbv-maxrate for a specific level?
Any suggestion for a better quality and compatibility are always good.
Thanks!
