The Input Settings tab also contains Proc Amp (processing amplifier) settings. Input
Proc Amp adjustments are applied after LiveMatte is processed, which can help when
composing greenscreen shots to match a background or LiveSet.
You may also notice that changes to Proc Amp settings affect stopped (or frozen)
sources, including live camera feeds.
A switch at the top of the Proc Amp control group toggles the feature on/off. Other
controls operate as follows:

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%).
