Blending Mode Specifies the blending mode the effect uses to create an interaction between the checkerboard
pattern and the original layer. The default None mode renders the checkerboard pattern only.
Circle effect
The Circle effect creates either a customizable solid circle or ring.
Circle effect: Original image (left), circle with no edge (center), and circle specifying a Thickness & Feather Radius edge (right)
Adjust the following controls for the Circle effect:
Center Specifies the center point of the circle.
Radius Specifies the size of the radius, in pixels. (If you set the radius to be larger than your original source clip,
either portions or all of the circle’s edge may fall outside the composition frame, depending upon the location of the
circle’s center point.)
Edge Specifies the shape and edge treatment of the circle. Depending upon the option, the slider changes its name
to correspond to the option. Choose one of the following options from the menu, and use the slider to adjust the
option:
• None Creates a solid circle.
• Edge Radius Creates a ring. The difference in the values set for this control and Radius determines the ring’s
width.
• Thickness Creates a ring with a specified thickness. The corresponding slider measures the ring thickness in
pixels.
• Thickness * Radius Creates a ring that uses the Radius value to determine the Thickness value. As you increase
the Radius value of the ring, the Thickness value increases proportionally.
• Thickness & Feather * Radius Creates a ring that uses the Radius value to determine both the Thickness and
Feather values. As you increase the Radius value, the Thickness and Feather values scale proportionally.
Feather Specifies the amount of feather applied to the edge of the circle. Increasing this amount softens the edges of
the circle, blending it with whatever appears behind it. Decreasing this amount sharpens the edge of the circle.
Note: Feather Inner Edge is disabled when Edge is set to None, since there is no inner edge on a solid circle.
Invert Circle Specifies that the circle matte is inverted, if this box is checked.
Color Specifies the color that fills the circle.
Opacity Specifies the transparency of the circle.
Blending Mode Specifies the blending mode that the effect uses to combine the circle and the original clip. None
displays only the circle without the original clip.
