7.1.2 PROC AMP
Proc Amp adjustments can be toggled on and off using the Enable Proc Amp switch at upper left
in the Main and Multiview panes (note that the Multiview output Proc Amp affects only
Program and Preview displays), or reset by clicking the Restore Defaults button. Each Proc Amp
has numeric slider controls for:

Brightness : Adjustment range from -50 to +50 IRE (the default being 0). As reference,
the full luminance range of the visible portion of a video signal can be thought of as ‘100
IRE units’ (named for the Institute of Radio Engineers) – ignoring minor regional
variations.

Contrast – Adjustment range from 25 - 400% (default 100%).

Hue – Adjustment range from -180° to +180°. Adjusts the master color of the video
signal from the attached source, swinging the entire image through the color wheel’s
spectrum.

Saturation – Adjustment range from 0-500%. Zero saturation results in a ‘black and
white’ picture; increased saturation results in richer colors. High saturation values can
exaggerate the color portion of the signal. Note that over-saturated colors are
considered illegal for broadcast transmission, and may result in display problems on
some devices.
Hint: your TriCaster system provides Waveform/Vectorscope monitors, an invaluable way to
accurately monitor the video signal to avoid issues such as illegal color.
