Wave Warp effect

The Wave Warp effect produces the appearance of a wave traveling across an image. You can produce a variety of

different wave shapes, including square, circular, and sine waves. The Wave Warp effect is automatically animated at

a constant speed across the time range (without keyframes or expressions). To vary speeds, set keyframes or

expressions.

This effect works with 8-bpc and 16-bpc color.

Wave Type The shape of the wave.

Wave Height The distance, in pixels, between wave peaks.

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 or

expressions 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 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 greatly increase rendering time. Anti-aliasing is performed only

if the layer quality setting is Best.

Tiago Dias provides a tutorial on his website that shows how to use the CC Light Rays effect.

4-Color Gradient effect

The 4-Color Gradient effect produces a four-color gradient. The gradient is defined by four effect points, the positions

and colors of which can be animated using the Positions & Colors controls. The gradient is composed of four solid-

color circles blended together, each with an effect point as its center.

This effect works with 8-bpc and 16-bpc color.

Blend Higher values create more gradual transitions between colors.

Jitter The amount of jitter (noise) in the gradient. The jitter, which reduces banding, affects only those areas where

banding could occur.

Opacity The opacity of the gradient, as a fraction of the Opacity value for the layer.

Blending Mode The blending mode to use in combining the gradient with the layer.
