Switching Backgrounds
Chapter 4 Basic Operations
The pressed button lights in green. This indicates that the
selected video is not being output from a PGM connector.
In the multi-view screen, the preset video is surrounded by
a frame. When the switcher is shipped from the factory, the
color of the frame is set to green.
Switching Backgrounds
A replacement of one or more of the video elements that
make up the current program output by another video
element is called a “transition”.
Video elements include the background and keys 1 to 4. A
transition can involve changes in one element or
simultaneous changes in a number of elements.
There are two main types of transitions.
• Transitions in which the next video appears instantly.
This type of transition is called a “cut”.
• Transitions in which the next video appears gradually
over a specified time through the application of an effect.
Two of the most commonly used effect types are mixes
and wipes.
This section explains how to switch the background.
Cutting to a New Background
Basic cut operations
There are two ways to cut to a new background.
• Cut directly to the next background by pressing a
cross-point selection button.
• Check the next background in the preview screen, and
then press the CUT button.
The figure below shows the flow of cut operations.
Cutting directly with the cross-point
selection buttons
If you simply want to switch to other video inputs, you can
press the cross-point selection buttons to which those
inputs have been assigned, pressing one button after
another.
By installing the optional BKDF-950 Multi Viewer Board,
you can check program video, preview video, and multiple
video inputs at the same time on a video monitor connected
to the processor unit. This is very convenient when you
select video signals.
