Lens Distortion effect (Windows only)
The Lens Distortion effect simulates a distorted lens through which the clip is viewed.
Curvature Changes the curvature of the lens. Specify a negative value to make the image concave, or a positive value
to make the image convex.
Vertical and Horizontal Decentering Displace the focal point of the lens, making the image bend and smear. At
extreme settings, the image wraps in on itself.
Vertical and Horizontal Prism FX Create a result similar to vertical and horizontal decentering, except that at
extreme values the image doesn’t wrap in on itself.
Fill Color Specifies the background color.
Fill Alpha Channel Makes the background transparent so that underlying tracks are visible. In the Effect Controls
panel, click Setup to access this option.
Magnify effect
The Magnify effect enlarges all or part of an image. This effect can act like a magnifying glass placed over an area of
the image, or you can use it to scale the entire image far beyond 100% while maintaining resolution.
