HDR encoding

[mparade]

If the field is greyed out, it is probably because Hybrid assumed this should be set automatically,.. (check the other enabled optins) using a custom command line usually is the wrong approach.

Yes, Hybrid can do cropping in 10/16 bit.

Do you think HDR data is independent from the bit depth of the video (number of steps between each color)?
I would prefer 12 bit HDR output in case of 10 bit HDR sources as well, but do not know if it has some impact on the HDR properties during encoding.
