TriCaster Advanced Edition provides extensive color control processing options for every video source.
These are hosted in the Color tab of the Input Configuration panel.
A UTO C OLOR
Lighting conditions can change dramatically during many live events, especially those held outdoors. Adding
to this problem, production usually involves multiple cameras and, all too often, these may not have uniform
color characteristics. Ensuring consistent color when switching from one angle to another, avoiding
unwelcome brightness or color shifts as evening falls or when a cloud obscures the sun briefly can be
troublesome, and expensive.
To help you overcome these problems, TriCaster Advanced Edition provides Auto Color, a unique feature
capable of dynamically adapting the color characteristics of your video sources as lighting conditions vary.
For many productions, simply enabling the Auto Color switch is all it takes to produce a show that looks
amazingly consistent.
M ULTICAM
By default, each camera with Auto Color enabled is processed uniquely – without reference to other sources.
Often, though, even greater consistency can be achieved by treating sources in similar illumination
environments as a group. Enable Multicam for several cameras causes Auto Color to evaluate and adjust
these cameras in unison. You might, for example, enable Multicam for court-side cameras in an interior
sports venue, while treating exterior or studio feeds individually.
L ISTEN O NLY
The Listen Only switch allows you to include a source in the Multicam group without adding its own feed to
the group evaluation. Thus a camera trained on a giant purple dinosaur can be automatically corrected
without disproportionately biasing the group evaluation and consequent Auto Color correction.
Alternatively, one might enable Multicam for a number of sources, turning Listen Only on for all but one
camera – effectively making that camera the color reference all other cameras in the group will follow.
Note: The Proc Amp, discussed next, is downstream of the Auto Color system. This allows you to apply further
manual color adjustments to your individual sources, whether for fine tuning or to achieve a specific “look”.
