Cut Transitions
The cut is the most basic transition that can be performed on the switcher. In a cut transition the
program output is immediately changed from one source to another.
Program output for a cut transition.
A cut transition can be performed directly from the program bus, or using the CUT button in the
transition control block.
Program Bus
When a cut transition is performed from the program bus, only the background will be changed,
and all upstream and downstream keys will maintain their current state.
To perform a cut transition from the program bus
On the program bus, select the video source that you want on the program output.
The program output will immediately change to the new source.
Press any of the source buttons on the program row
to perform a cut transition from the program bus
CUT Button
When a cut transition is performed using the CUT button, any upstream keys that were selected
in the next transition and any downstream keys that were tied to the transition control will also
change state. For example, a downstream key tied to the transition control will cut ON if off air,
or cut OFF if on air. Similarly, any upstream keys selected in the next transition will be cut on if
they were off air, or cut off if they were on air.
Press the button marked CUT in the transition
control block to perform a cut transition
