Tracker - NewTek TriCaster Mini User Manual

A Hotspot is a square, user-defined region of the screen
that (when active) detects opacity changes inside its
boundaries. This is why the feature is paired with
LiveMatte in the TriCaster interface (Hotspots do not
work without LiveMatte being 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 depth in Chapter 17, Macros, Automation and Remote Control.

8.2.8 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 8.2.6).
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).
