Setting up a Pattern Key on the Upstream Keyer using
ATEM 1 M/E 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
rest the position to its default.
This button inverts which the region is filled with the fill source.
For example, fill a region outside of a circle by positioning the circle wipe
as desired and then setting invert pattern to 'on'.
Increases and decreases the size of the selected pattern.
Some patterns may have their symmetry or aspect ratio adjusted.
Circle patterns may be adjusted to become horizontal or vertical ellipses.
Changes the softness of the edge of the key signal.
These settings let you change the position of the pattern on the screen.
Allows you to mask out sections of the key. For example, if the green
screen does not fill the edges of the screen, you can use the mask setting
to select only the area of the screen you want to use.
To return the mask to its default symetrical settings, select 'reset mask' and
press the set button.
