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.
Direction
The normal direction moves the graphic from left to right, and the reverse direction
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’ direction
settings indicates the direction of the next transition.
Fill Source
The fill signal is the graphic used to move across the top of the transition.
Enable Key
Enables or disables the key. Set to ‘on’ to enable, or ‘off’ to disable.
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.
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.
