Thus, the Vert Position, Horiz Position and Phase settings allow you to tweak synchronization to arrive at an
optimum match between devices. Typically, these settings are fine-tuned with the aid of a downstream
Vectorscope and Waveform Monitor. (A discussion of these adjustments goes beyond the scope of this
manual, but a quick online search for the keywords “genlock” and “adjust” turns up a number of excellent
references).

The ‘bi-level’ reference signal long used for standard definition television is often used for genlocking both
SD and HD installations.
However, if you are supplying an HD reference signal to TriCaster’s Genlock Input (and your other
equipment), select the HD (Tri-level) switch in the Reference Type area of TriCaster’s Genlock settings.
Note: Reference Type options do not appear for SD sessions.
8.2.4
CENTER FREQUENCY
This setting is applied when a genlock reference signal is not in use. To adjust the setting, supply color bars
to an input and pass TriCaster’s video output to a downstream vectorscope. The vectorscope display is
completely stable when Center Frequency is properly adjusted.
Note: See also Section 8.1.1, Frame Sync .

PTZ
FIGURE 8-23
PTZ (pan-tilt-zoom), or ‘robotic’ cameras can play important roles in certain types of productions. These
systems range widely in price, from a few hundred dollars to those in the ‘six figure’ range, with an equally
diverse range of quality and features.
Note: TriCaster Mini SDI does not support PTZ Optics SDI cameras.
