Distort effects
Bend effect
The Bend effect distorts a clip by producing the appearance of a wave traveling both vertically and horizontally
through the clip. You can produce a number of different wave shapes at various sizes and rates.
The Bend effect has the following settings:
Direction
Specifies the direction of the wave:
•
In
Specifies that waves move toward the center of the clip.
•
Out
Specifies that waves start in the center and move to the edge of the clip.
Wave
Specifies the shape of the wave. Choose from a sine wave, circle, triangle, or square.
Intensity
Specifies the height of the wave.
Rate
Specifies the frequency of the wave. To produce a wave only vertically or horizontally, move the Rate slider all
the way to the left for the direction you do not want.
Width
Specifies the wave width.
Corner Pin effect
The Corner Pin effect distorts an image by changing the position of each of its four corners. Use it to stretch, shrink,
skew, or twist an image, or to simulate perspective or movement that pivots from the edge of a clip, such as a door
opening.
Note:
You can directly manipulate the Corner Pin effect properties in the Program monitor when you click the Transform
icon next to Corner Pin in the Effect Controls panel. Drag one of the four corner handles to adjust the properties.
Corner Pin effect: Original image (left), corner moved (center), and final image (right)
Lens Distortion effect
The Lens Distortion effect simulates a distorted lens through which the clip is viewed.
The Lens Distortion effect has the following settings:
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.
