Cuts
A Cut is an instantaneous transition between
video sources. Unlike all the other transition
types, there are no intermediate steps between
the video source that is on-air, and the video
source you are transitioning to.
Cut
Figure 5: Cut Transitions
A cut is performed either by selecting difference
sources on a background or key bus, or by
pressing a
CUT
button.
Dissolves
A Dissolve is a gradual fade between video
sources. For a Background transition, the video
signal on the Background bus and the video
signal on the Preset bus are mixed together until
the Preset bus video signal completely replaces
the Background bus video signal. During the
transition, both the Background bus and the
Preset bus are on-air. Only after the transition
has completed do the crosspoint selection
flip-flop between the buses.
Figure 6: Dissolve Transition
Wipes
A Wipe is a gradual transition where one video
signal is replaced with another according to a
wipe pattern. For a Background transition, the
video signal on the Background bus is replaced
by the video signal on the Preset bus according
to the wipe pattern. In the example below, a line
wipe is being used. During the transition, both
the Background bus and the Preset bus are
on-air. Only after the transition has completed
do the crosspoint selection flip-flop between the
buses.
Figure 7: Wipes
The Pattern Select menu, displayed when a
wipe is selected, shows 32 pre-assigned patterns,
and 8 user-assignable patterns.
To Set Up a Wipe
A wipe transition requires that you select a wipe
pattern, and set the direction and number/size
of the wipe pattern.
1.
Press
WIPE
on the Transition module.
2.
Press the pattern button for the pattern you
want to use.
3.
Press
Direction
to select if the wipe moves
forward (
Fwd
) or in reverse (
Rev
).
For example, if the circle pattern is used,
toggling between reverse and forward
changes whether the transition starts as a
circle in the center of the screen and
expands out, or the circle starts off-screen
and shrinks down to the center.
4.
Press
Flip Flop
to select if the wipe moves
in the opposite direction with every
transition (
On
), or always moves in one
direction (
Off
).
