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 to select on the advanced panel or
software control. 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 flying key enabled. To free DVE from the upstream keyer, change the key
type to anything other than DVE or disable flying 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.
