‘reverse direction’. You can also enable ‘flip flop’ which will let the effect move forwards
and backwards with each performance of the transition, rather than repeating the same
movement direction.
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.
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.
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.
