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 the following 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.
• DVE — The video image is taken off-air using a
selected digital video effect.

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.
To cut on the Program bus:
