Effects and transitions
Last updated 11/6/2011
Wave Width The size of the wave in pixels.
Direction The direction the wave travels across the image. For example, a value of 225° makes the waves travel
diagonally from upper right to lower left.
Wave Speed The speed (in cycles per second) at which the waves travel. A negative value reverses the wave direction,
and a value of 0 produces no movement. To vary wave speed over time, set this control to 0, and then set keyframes
for the Phase property.
Pinning Which edges to pin so that the pixels along those edges aren’t displaced.
Phase The point along the waveform at which a wave cycle begins. For example, 0° starts the wave at the midpoint of
its downward slope, and 90° starts it at the lowest point in the trough.
Antialiasing (Best Quality) Sets the amount of anti-aliasing, or edge smoothing, to perform on the image. In many
cases, lower settings produce satisfactory results; a high setting can significantly increase rendering time.
GPU effects (Windows only)
Page Curl effect (Windows only)
Use Page Curl to simulate a page slowly turning. As the “page” turns, you see the back of the image mapped to the
opposite side of the curl. The back of the image is actually a mirror image of the front. This effect is most useful as a
transition where you would like to have a high-quality, textured page peel effect to reveal an underlying frame. Page
Curl includes controls that function identically to the controls in the Ripple Effect (Circular).
Page Curl adds the following controls not in the Ripple (Circular) Effect:
Angle Of Curl Specifies where on the image edge the curl begins.
Curl Amount Specifies how far into the image that the curl extends.

Refraction effect (Windows only)
Use this effect to create a ripple and add a refractive look to the surface of your image. This simulates how an object
distorts when it is just beneath the surface of moving water or behind a refractive object such as frosted glass.
Ripple Amount Specifies the size of the ripples. Animating this property creates the effect of moving water.
Refractive Index Specifies the ratio of the light’s velocity as it passes from a rarer to a denser medium.
Bump Specifies the grain amount on the surface.
Depth Specifies the depth of the surface through which you are viewing the image. For example, in the case of
simulating an underwater object, adjusting this value changes how deep an object appears to be in the water.
Ripple (Circular) effect (Windows only)
Use Ripple (Circular) to create an effect similar to concentric ripples on the surface of water.
Surface Angle X and Y Specify the degree of rotation on the designated Cartesian axis.
