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, you need to set keyframes
or expressions.
This effect works with 8-bpc and 16-bpc color.

Adjust the following controls for the Wave Warp effect:
Specifies the shape of the wave.
Wave Type
Specifies the height of the wave. Taller waves generally produce greater distortion.
Wave Height
Specifies the distance, in pixels, between wave peaks. Smaller values produce more waves.
Wave Width
Specifies the direction the wave travels across the image. For example, a value of 90 degrees makes waves
Direction
travel from left to right. A value of 180 degrees makes waves travel from top to bottom, and a value of 225 degrees
makes the waves travel diagonally from upper right to lower left.
Sets the speed (cycles per second) at which the waves travel. When you specify Wave Speed, the ripples
Wave Speed
are automatically animated at a constant speed across the time range (without keyframes). Click the Wave Speed
value to specify negative values or values greater than 5. 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 of the layer.
Specifies areas of the image to be excluded from the wave. For example, if All Edges is selected, the wave
Pinning
does not travel across the edges of the image.
Specifies the point along the waveform at which a wave cycle begins. The default value of 0 degrees starts the
Phase
wave at the midpoint of its downward slope; 90 degrees starts it at the lowest point in the trough; 180 degrees starts
it at the midpoint of the upward slope, and so on.
Sets the amount of anti-aliasing, or edge smoothing, to perform on the image. Anti-aliasing is applied
Antialiasing
only when the layer is set to Best quality. In many cases, lower settings produce satisfactory results; a high setting can
significantly increase rendering time.
