3 Press the right arrow in the system control buttons to adjust the key settings. Enable
the key and select the fill and key source. If you need to make adjustments to the key,
for example adjusting clip and gain settings, press the right arrow in the system control
buttons to access the key parameters.
TIP Typically, for a graphic transition, the source would normally be a graphic
loaded in a media player. By default, when you select a media player for the fill
source, the key source will automatically select the media player key channel
and set pre multiplied key to ‘on’. This means a graphic with a key matte
embedded in the alpha channel will automatically be selected by the switcher.
You can disable pre multiplied key and change the key source if you want to
use a separate media file on a different media player, or a different input source.
4 Press the auto button to perform the transition as an auto transition, or use the fader
bar for a manual transition.
Description of graphic wipe parameters
Rate
Rate specifies the length of the transition in seconds and frames. Therate can be
adjustedusing the rate knob or by entering a number on the number pad and pressing the
set ratebutton.
Normal
The normal direction moves the graphic from left to right.
Reverse
Reverse changes the direction so that it moves the graphic from right to left.
FlipFlop
When FlipFlop mode is toggled on, the transition changes between normal and reverse every
time the transition is executed. The ‘Normal’ or ‘Reverse’ light indicates the direction of the
next transition.
Fill Source
The fill signal is the graphic used to move across the top of the transition.
Key Source
The key signal is a grayscale image that defines the region in the graphic that will be
removed so that the fill signal can be correctly stacked on top of the wipe.
Sharing DVE resources
The one DVE channel available in the switcher can be used to perform DVE transitions or it can
be used in an upstream keyer. When you select a DVE transition, if the DVE is used elsewhere
in the system, the DVE transition type will not be available and, on the broadcast panel, a DVE
unavailable message will be displayed. In order to use the graphic wipe transition you must free
the DVE from where it is currently used. Verify that the upstream keys currently on program or
preview are not DVE keys and do not have fly key enabled. To free DVE from the upstream
keyer, change the key type to anything other than DVE or disable fly key. The DVE will be
released and therefore available for use as a graphic wipe.
Graphic wipe images
The graphic wipe feature requires a static graphic that is used as a moving border for a
horizontal wipe. This graphic should be a vertical ‘banner’ type graphic that is no more than
25% of the total screen width.
