Auto Color; Proc Amp - Panasonic AV-HLC100E Operating Instructions Manual

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, the Auto Color feature updates the color characteristics of your
video sources as lighting conditions vary. In many cases, simply enabling the Auto Color switch is all it
takes to produce a show that looks amazingly consistent.
Multicam
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.
Listen Only
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".
