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 (Figure 3-1). 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.
