Handbrake, HDR10 and MaxFALL, MaxCLL parameters/values

Post by justinhow » Mon Jan 14, 2019 11:49 am

I am successfully using the handbrake cli (latest version) to encode large HDR10 HEVC videos to a smaller mkv, keeping (nearly) all the HEVC/HDR info/paremeters.

One current limitation of Handbrake is that it appears to lose the MaxFALL and MaxCLL HDR10 parameters which are potentially valuable bits of information.

I can extract these paremeters from the original HEVC file using mediainfo, and I wondered whether there was anyway to pass the parameters/values directly to the x265 encoder (which supports them as I understand) so they still exist in the encoded mkv video file. I have no idea whether this is possible and if so how to do it.

After posting i realise this should probably have been posted in the handbrake CLI section, although I am happy to get an answer that refers to the GUI or the CLI

Think I have found the answer over at https://github.com/HandBrake/HandBrake/issues/1196

HB has an 8-bit video pipeline, so the 10-bit HDR is lost regardless of your input or output.
