Basic Operation

This chapter describes the general operation of your switcher. Basic information is provided to help get you up and running quickly.

Transition Overview

Transitions allow you to replace the on-air video source with another source. During a transition, the source you selected on the Preset bus becomes active on the Program bus and the source that was active on the Program bus is now on the Preset bus.

You can perform three types of transitions:

•Cuts — The video image instantly switches between selected sources.

•Dissolves — The video image gradually fades from the on-air source to the selected source.

•Wipes — The selected source wipes over the on-air source using a user-specified pattern and direction.

Cutting on the Program Bus

Cuts are the simplest transition, performing an instantaneous change between sources. You can perform a cut transition as described in the previous section, or you can perform the transition directly on the Program bus.

This also applies to keys. If a key is on-air, you can select alternate sources on the Key/Aux bus and have them instantly cut on-air.
