The State Change implementation thus allows you to automate all manner of operations based on such things
as the following:
• Program or Preview row selection.
• Displaying/ hiding the source in a DSK or KEY channel.
• Selecting/de-selecting it on an M/E ’s A row, or any M/E row, or …
• Showing or hiding a source on the Program or Preview output.
This is immensely powerful, and lends itself to endless applications, such as (to suggest just a few):
• Automatically fly in a title as you switch to remote sources, and remove it after a specified time
• Select a different Audio Mixer preset automatically when you switch from viewing a source in the B
monitor of a virtual set on Program to displaying it full-screen
• Then change back to the original audio setup when you switch back to the anchor desk.
The possibilities are truly endless.
Hint: More coverage of both macros and the larger topic of automation can be found in the accompanying
Automation and Integration Guide.

The next control group in the Automation tab is devoted to Hotspots – another powerful and interactive
automation feature. 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 to work properly).
With LiveMatte properly configured, the Hotspot feature can trigger a macro when opaque pixels are newly
detected in an active Hotspot.
For example, someone in a greenscreen set can trigger a macro by walking into a location in the frame where
a hotspot has been defined. A second macro when all opaque pixels
– i.e., the talent – moves out of the deinfed
hotspot zone. All manner of creative implementations are possible.
Hotspot setup, options and use are further discussed in Chapter 5 of the supplemental Automation and
Integration Guide .

The Tracker control group provides real-time 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 (see Chapter 13).
