Pattern Key Settings
To set up a pattern key on upstream keyer 1 on an ATEM advanced panel:
1 Press the KEY 1 next transition button to enable the key on the preview output. This
automatically selects the keyers menu on the system control LCD. Pressing the KEY 1
next transition button ties the key to the next transition so it will transition to air when
the next transition is performed.
2 In the keyers LCD menu, select the 'pattern' key type using the corresponding 'key
type' control knob.
3 Select the fill source using the corresponding soft control knob or by pressing a source
button on the source select bus.
4 Turn the corresponding soft control knobs to choose the 'pattern' you want for the
pattern key and set the 'size' of the pattern.
5 Press the system control left and right arrow buttons to navigate through the pattern
key parameters and adjust settings using the control knobs. Watch the preview output
as you refine the key.
TIP Some patterns can have their center point repositioned. Use the joystick to move
the position of the pattern. If you need to reset the position, navigate to the 'pattern
type' setting, change it to another pattern and then return to your chosen pattern to
reset the position to its default.
