How to preserve HDR 10 info? #209

Open canbonbon opened 3 years ago

canbonbon commented 3 years ago

Converting 4K movies to H265 using standard settings looses HRD10 information. Is there a flag or setting I could use to preserve HDR10 information in the movie? Let me know when you get a chance.

IFME is follow x265, if you manage self update x265 to latest build, you can use Add Command Line for Encoder, and put like:

--dolby-vision-profile  <5|8.1|8.2> --dolby-vision-rpu <Dolby Vision metadata RPU file>

By default, IFME only pass video metadata, if has HDR, it will encode in HDR automatically,

if output not satisfied, you can clock Encoder Command Line button and add extra x265 commands

apparently FFmpeg did not pass HDR metadata, I keep in view for now

Fastflix also uses ffmpeg and is able to pass the HDR info. Maybe you could check how they are doing that.

wow, this HDR especially Dolbyvision make HDR complicated.

This mean, HDR10 video only exist on HEVC?

I can add hdr10plus_parser.exe into the program, if video is HEVC HDR10, parse into JSON and read JSON and pass to x265
