I just have to start from part 4 and change the source profile in part 5.2 for my icm profile, the output encoding to 0-255 and the gamma mapping to 2.25 absolute in part 5.5. Then load the new 3D LUT in BT.709 in madVR, right ?
Thanks for your help. |
you need to set your ICM file as
target.
and you have to leave output at 16-235 madVR thinks every 3d lut is 16-235. dispcalgui 2.6 shouldn't even give you an option to change this any more.
if you want to use bt 1886 leave gamma at 2.4.
gamma should be changed based on your room lightning. "correct" is 2.2 and for dark rooms 2.4 is recommended. bt 1886 is very complicated just leave it at 2.4. not sure if your ICM has any information for your black point so not sure if it has any effect or just results in gamma 2.4.
and yes you add it in bt 709 and don't forget to check disable GPU gamma ramp.
