Adjust this filter using the parameter controls in the Filters Inspector:
Center: Sets the position of the center of the lens. You can also drag the Center onscreen control in the Canvas.
Radius: Sets the radius of the ring. Drag the inner circle of the onscreen controls to adjust the Radius value. Drag between the inner and outer circles to adjust the Radius and Thickness parameters simultaneously.
Thickness: Sets the thickness of the ring as a percentage of the radius. Values range from 0 (no thickness) to 1.00 (no hole in the center of the ring lens). Drag the outer circle of the onscreen controls to adjust the Thickness value. Drag between the inner and outer circles to adjust the Thickness and Radius parameters simultaneously.
Refraction: Sets the amount of refraction of the lens.
Crop: Sets whether the filtered image is sharply cropped at its original boundaries. When this checkbox is deselected, the filter affects the edges of the image.
Mix: Sets the percentage of the original image to be blended with the distorted image.
Publish OSC: Publishes the filter’s onscreen controls in Final Cut Pro X. For more information on creating content for use in Final Cut Pro, see Final Cut Pro templates overview.
