Performing a Graphic Transition
To perform a graphic transition on the ATEM 1 M/E Advanced Panel:
1 Press the DVE transition type button in the transition control block. The DVE settings
menu will appear on the LCD.
If the DVE is already being used in an upstream key, the DVE transition type will not be
available for selection until the key is taken off air and off next transition.
Refer to 'sharing DVE resources' later in this section for more information.
2 Press the 'effect' soft button in the LCD menu to open the effect settings, and set
the effect to a graphic wipe by selecting the graphic wipe icon using the 'effect' soft
control knob.
The default direction is left to right, but you can change the direction by selecting
'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.
