Uses a zoom blur rather than a Gaussian blur to distribute a glow. The resulting effect is that of light rays shining through an object from a specified point.
Adjust this filter using the parameter controls in the Filters Inspector:
Amount: Sets the amount of the light ray effect. Larger values extend the length of the rays.
Center: Sets the position of the center point of the light source. You can also drag the center onscreen in the Canvas.
Glow: Sets the brightness multiplier of the light rays.
Expansion: Sets the distance the light rays extend outside the boundary of the layer.
Clip to White: Any color channel exceeding the maximum value of 1 is clipped to 1.
Mix: Sets the percentage of the original image to be blended with the filtered 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.
