To set up a pattern key on upstream keyer 1 on the broadcast panel:
Step 1.
Press the KEY 1 button to enable the keyer on the preview output. The system control will
dynamically navigate to the KEY 1 menu. You can manually navigate to the KEY 1 menu by
pressing HOME > EFFECTS KEYS > KEY 1.

Step 3.
The destination display will say key1fill on the ATEM 1 M/E Broadcast Panel. On the ATEM 2 M/E
Broadcast Panel, the KEY 1/CUT button will be lit. Select the fill source on the select bus. Since
the key signal is automatically created by the internal pattern generator from the fill source, the
cut source is ignored.

Select the PATTRN MENU button and use the menu buttons to select a pattern.
Step 5.
Adjust the pattern key controls to refine the key.
Pattern key parameters:
Size
Increases and decreases the size of the selected pattern.
Symmetry
Some patterns may have their symmetry or aspect ratio adjusted. Circle patterns
may be adjusted to become horizontal or vertical ellipses. The symmetry
adjustment is on the joystick's z axis when you are on the pattern selection page
of the keyer you are setting up. Twist the joystick knob to adjust its symmetry.
Soft
Changes the softness of the edge of the key signal.
Inverse
The reverse button is used to invert which 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 selecting inverse.
