Section 3 — Switcher Concepts
Transitions
A transition is a change from one video picture to another. The
switcher provides three methods for making video transitions:
■
Cuts
■
Mixes
■
Wipes
Cut Transition
A cut is an instantaneous switch from one picture to another. A
background cut, for example, switches the on-air Program output
instantly from the picture selected on the Program bus to the
picture selected on the Preset bus. A cut can also be used to switch
a key on or off air instantaneously.
Mix Transition
A mix is a transition from one picture to another in which the new
picture mixes into and then replaces the picture that was already
on air (
). The switcher allows you to mix from one
background picture to another or to mix up to three separate key
layers on or off over a background. Background and key mixes
can be done separately or simultaneously.
