A.1.4 COLOR CORRECT MISMATCHED CAMERAS?
TriCaster permits the use of sources that do not match the current session format. You might connect an SD
camera during an HD session, for example. The official broadcast standard for SD video is Rec. 601, but HD
video conforms to Rec. 709. TriCaster’s output color space is governed by the session format.
When the natural color space for a connected source does not match TriCaster’s current output specification
(in this example, Rec. 709), TriCaster automatically attempts to compensate – but as always, it’s good to refer
to the scopes for critical accuracy.
As required, TriCaster’s Waveform and Vectorscope displays can be used to monitor corrections made using
the Proc Amp tools. (Scope calibration automatically conforms to the broadcast color specification for the
current session – HD or SD, and is appropriately labeled as a convenient reminder.)
A.1.5 CONNECT MONITORS?
