Section 4— Switcher Operations

Transitions - Mix/Effects Bus Operations

A transition is a change from one combination of picture elements 
to another combination. This change can take the form of a cut, a 
mix, or a wipe and can be used to switch background scenes or 
insert or remove a key. We will use a Mix/Effects bus to 
demonstrate basic transitions. 

Set up the switcher crosspoint buses as follows for this Transitions 
subsection:

1.

 

2.

Using the Preview buttons, select M/E 1 (in order to see the 
preview or “off-air” source on the Preview monitor). 
(Requires the Look-Ahead Preview option.)

Background Cut

A cut is an instantaneous switch from one picture to another. To 
cut between M/E 1 bus A (Program) and bus B (Preset) 
Background bus sources, do the following:

1.

Select M/E 1 on the E-MEM Subpanel. Press CWB twice.

2.

Select Source 1 on the A bus background 

crosspoint 

row. 

Source 1’s video should now be seen on the PGM monitor.

3.

Select Source 2 on the B bus background 

crosspoint 

row. If 

you have the Look Ahead Preview option set up for Look 
Ahead mode, Source 2 should now appear on the Preview 
monitor.

NOTE:  

To ensure that Preview Mode is set to Lookahead, access the 

Config/User Prefs/Preview Prefs Menu. Set 

PVW MODE

 on M/E 1 to 

LOOK AHEAD

.
