viewed from above). The Phase setting ensures proper color alignment, corresponding to making
sure everyone is on the left or right foot at the same time.
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).
SECTION 4.6 REFERENCE TYPE
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
TalkShow’s Genlock Input (and your other equipment), select the HD (Tri-level) switch in the
Reference Type area of the Genlock settings pane.
SECTION 4.7 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 TalkShow’s video output to a downstream vectorscope. The
vectorscope display is completely stable when Center Frequency is properly adjusted.
