H OT S POTS
FIGURE 78
The lower portion of the Automation tab is devoted to Hotspots – another of TriCaster’s powerful interactive
automation features. A Hotspot is a user-defined region of the screen that (when active) detects opacity
changes inside its boundaries (for which reason, Hotspots require LiveMatte to be enabled).
With LiveMatte properly configured, the Hotspot feature can trigger a macro when opaque pixels are newly
detected in an active Hotspot (as, for example, when talent in a greenscreen set walks into that location in
the frame), and a second macro when all opaque pixels move out of the region. All manner of creative
implementations are possible. Hotspot setup, options and use is discussed in Chapter 17, Macros, Automation
and Remote Control.
8.2.9 TRACKER
(TriCaster 8000 only) The Tracker tab provides control
over TriCaster’s realtime motion tracking features.
This feature allows you to choose a colored region of
the video frame using tools similar to those found in
the LiveMatte tab (Section 8.2.7).
The tracked region is defined by choosing a primary Color using
the color picker tool. The Tracker follows this region as it moves
and shifts within the frame over time, and outputs the motion
data to TriCaster.
In turn, Tracker output from one source can be used to control
the placement of other video sources configured to do so in their
individual Position panels (supplied wherever appropriate in
DSK controls and M/E panes).
A DJUSTING T OLERANCE
Click the eyedropper, keep the mouse button depressed, and drag the pointer over top of the monitor
showing the source you want to track (Figure 79). The color swatch updates constantly as you drag, until you
release the button to make a selection.
