Colour Scaling Nucoda and Phoenix 2014 Install Manual
Colour Scaling
Each project includes a configuration option that defines the project colour scaling.
Colour scaling modes affect :
● SDI Monitoring and whether this SDI signal is scaled or unscaled (untouched).
● Video I/O and whether the SDI signal is scaled or unscaled (untouched).
● Black and white levels to use for timeline filler, transitions, pan/scan blanking,
fade to colour
● Colour Tool behaviour and what black and white levels they pivot around
● Algorithm effectiveness for scene detection and DVO tools
alert!
The scaling behaviour can include scaling and clipping of your output display and so
it is essential to understand and test this behaviour carefully, then configure for your
own workflow requirements.
Recommendations
The following colour scaling modes are recommended. A more detailed description is
given in subsequent pages and the appendix SMPTE / CGR Scaling on page 71.
Video/Linear Work
Use : Linear (SMPTE)
Video I/O will capture and lay-off the whole 0-1023 10 bit signal with no scaling or
clipping. The signal is untouched (in/out).
SDI monitoring will be unscaled and untouched, displaying all 0-1023 values.
Generated black and white levels inside your project (e.g. blanking, filler etc.) will
be SMPTE levels 64 and 940
By default, colour tools will pivot around 1023.
Film/Log Work
Use : Film Log
As above, video IO and monitoring will be unscaled and untouched 0-1023.
Generated black and white levels inside your project (e.g. blanking, filler etc.() will
be Cineon levels 95 and 685.
By default, colour tools will pivot around1023.

Preferences chapter).
