Convert 4K HLG -> HDR?

Hello,

I have a recording of a TV life show (.ts) which is in 4K HLG. Is it possible to convert this into 4K HDR using HandBrake?
Until yet, I did not find any settings for that. Could you please help me?

Or if it is not possible, could you please tell me any other tool which can do this?

Handbrake does not currently handle 10-bit HDR as an output, so the short answer is "no".

Thank you, in the meantime I found x265-10Bit. Isn't it that?

That will output a file with 10-bit color, but only 8-bit passes through handbrake's pipeline (i.e., the filters). A 10-bit color source will be converted to 8-bit color, then the output can be taken back to 10- or 12-bit, but it is NOT going to be HDR.

Thank you, then I will try to convert my 4K .ts HLG recorded file into best possible format for Apple TV (Infuse app for movie playback). So which settings should I use then you think?
And which settings are also very good 4K but would nit take days to convert on an i7?

To quote one of the developers, who write and understand the program...
