Specify the reference white level, in nits, for all of your SDR inputs. Use to correct brightness levels within
HDR10 outputs. The following color metadata must be present in your SDR input: color primaries, transfer
characteristics, and matrix coefficients. If your SDR input has missing color metadata, or if you want to correct
input color metadata, manually specify a color space in the input video selector. For 1,000 nit peak brightness
displays, we recommend that you set SDR reference white level to 203 (according to ITU-R BT.2408). Leave blank to
use the default value of 100, or specify an integer from 100 to 1000.
