captured (0-1023) and output/monitored (0-1023) as is.
Colour tools pivot around the SMPTE values 64 and 940.
Linear (CGR)
Scaled SDI
The SDI signal is scaled on both capture and output (monitoring and I/O). On
capture, we scale the 64-940 to 0-1023 and thus lose the any super blacks and
whites. On layoff (and monitoring), we scale the 0-1023 back to 64-940.
alert!
Linear (CGR) mode will limit your output to SMPTE levels (e.g. 64-940).
Colour tools pivot around the CGR values 0 and 1023.

In RGB 4:4:4 mode, CGR mode will not scale the SDI video signal

See appendix SMPTE / CGR Scaling on page 71 for more detailed diagrams
showing the signal path for Linear (SMPTE) and Linear (CGR) modes.
Colour Tools
The colour adaptive tools have their own independent scaling mode option with the
default taken from the main project setting. The scaling mode will affect the black and
white points used and the way the tool pivots around them when adjusting parameters.
