Card Wipe (available from the Adobe Web site)

This effect simulates the effect a group of people in a stadium with cards, holding the

cards that make a picture, and then ﬂipping them over to reveal a different picture. Card

Wipe gives you full control over the number of rows and columns of cards, the ﬂip

direction, and the transition direction, including the ability to use a gradient to determine

ﬂip order. Use the effects controls to adjust randomness and jitter. You can vary the rows

and columns to create venetian blind and chinese lantern effects.

For more information, see the After Effects product section on Adobe’s Web site.

Gradient Wipe

This effect creates transitions based on the luminance values of a second layer, called the

gradient layer. The luminance of a pixel in the gradient determines the time at which the

corresponding pixel in the ﬁrst layer will become transparent. Dark areas of the gradient

layer represent those areas which will become transparent ﬁrst, followed by lighter areas.

Iris Wipe

This effect creates a radial transition that reveals an underlying layer. Specify the number

of points used to create the iris using a range of 6 to 32 points, and specify whether an

inner Radius is used. When Use Inner Radius is selected, you can specify values for both the

Inner and Outer Radius; the iris is not visible when Outer Radius, Inner Radius, or both are

set to 0. The iris is roundest when both Outer Radius and Inner Radius are set to the same

value.

Iris Wipe creates a transition from one layer to another using an iris with seven points.

Linear Wipe

This effect performs a simple linear wipe of a layer in a speciﬁed direction. At Draft quality,

the edge of the wipe is not anti-aliased; at Best quality, the edge of the wipe is anti-aliased

and the feather is smooth.

The Wipe Angle option speciﬁes the direction that the wipe travels. For example, at 90

degrees the wipe travels from left to right.
