Video SMPTE / Full Range Colour Scaling
This section describes Video SMPTE and Full Range (CGR) colour scaling modes.
Using Video SMPTE video bars (64-940 or 0-100%), we will consider the SDI signal as it passes through the system when using the two modes Video SMPTE and Full Range.
These examples will use YCrCb 4:2:2 SDI signals.
Full Range mode does not scale RGB 4:4:4 signals unless you set the general.prefs option :
scale444 true
