Tips for HDR Master Display Information
Red, Green, Blue, White Point X and Y
Your color grader may provide numbers like this for X and Y points:

G (x=0.265, y=0.690)

B (x=0.150, y=0.060)

R (x=0.680, y=0.320)
You must convert these numbers to numbers like this:

G (13250, 34500)

B (7500, 3000)

R (34000, 16000)
To convert between the two formats, divide each number by 0.00002 as per the HEVC specification:
For example, 0.265 divided by 0.00002 is 13250.
Max/Min Luminescence
The maximum and minimum luminance are given in units of 0.0001 candelas per square meter. Your color grader may provide this value in candelas per square meter instead. If so, then convert these numbers by multiplying by 10,000, then entering the result in the UI.
For example, a value of 1000.0000 cd/m2 for max luminance would be converted to 10,000,000 and entered as that in the web interface.
