A transition is a change from one video picture to another. The 
switcher provides three methods for making video transitions:

■

Cuts

■

Mixes

■

Wipes

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.

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.
