Pattern key parameters:
Invert Pattern 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 enabling the invert pattern checkbox.
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.
Softness Changes the softness of the edge of the key signal.
Position X and Y These settings let you change the position of the pattern on the screen.
Mask 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 symmetrical settings, select ‘reset mask’
and press the set button.
