DUCCS: REC 709 preset gamma value? (NETFLIX requires 2.4)
Hi there
There is a REC 709 preset in DUCCS. I cannot adjust the Gamma. What is the default value?
Otherwise, what are the primary values and white point for REC 709, so I can make a custom profile?
Partial reply:
Primaries are:
XR: 0.64 | YR: 0.33 | XG: 0.30 | YG: 0.60 | XB: 0.15 | YB: 0.06 |
White point at CIE D65
Explanation:
REC 709 gamma is normally given by a composite function, linear for low Luma, then logarithmic (or exponential, I´m not a math teacher). Nevertheless, networks issue different specifications. NETFLIX requires a simple 2.4 gamma function. So what is the default vallue in DUCCS? And, if it isn´t 2.4, can anybody provide the primary values in order for me to make my own NETFLIX preset?
Thank you
