Hi,
Anybody knows when the regular version will support HDR and work internally in 10 bits?
At the moment, if I'm not mistaken, only the nightly builds do.

Re: HDR & 10 bits
The devs don’t usually set timeframes, it usually happens when it happens.
But just use the nightly, if it doesn’t work post a bug report.

Re: HDR & 10 bits
why HB still dosnt support nvenc 10Bit ?? ist 2021. FFMPEG easaly can do this with: ffmpeg -hwaccel nvdec -hwaccel_device 0 -vsync 0 -i "input.mkv" -map 0 -c copy -c0 hevc_nvenc -profile:v main10 -pix_fmt p010le -cq 26 -qmin 1 -qmax 51 -gpu 0 "out.mkv"
Re: HDR & 10 bits
As rollin_eng said, the nightly builds support 10 bits. I don't like much beta testing, but so far, it seems to work well.
About HDR10, a suggestion for the devs: it would be nice to be able to set the mastering display luminance values, although I confess having no idea if it's possible or not, and how much work it requires.
I'm recoding the Snyder's version of Justice League to get a 16:9 image instead of the ridiculous 4:3 one (who in hell can think about making a 4:3 UHD image?), and these values are not the same as in the original UHD BR, too high for my display.

Re: HDR & 10 bits
You can override the hdr10 metadata in the x265 additional options textfield. Currently x265 is the only encoder that writes those values to the video stream.
Re: HDR & 10 bits
You mean the 'Advanced Options' field?
What would be the syntax? Does not that imply altering the gamma too?
I don't know how these values are handled by the display.
Re: HDR & 10 bits
Something like max-cll=4000,1000:master-display=G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,1)
Gamma is an approximation of the transfer function of SD and HD video, HDR uses a different transfer function that can't be approximated with a simple quadratic function. Anyway, will it change the way the image is displayed? Probably.
