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.

Ripple Center

Specifies the X and Y location of the ripple center. You can also change this parameter directly in the

Monitor view.

Ripple Amount

Specifies the size of the ripples.

Key Light Angle A and B

Specify angular location of light source in polar coordinates. Angle A is on the Z axis, and

angle B is formed on XY plane.

Light Distance

Specifies the distance between the light source and the center of the ripple surface.

Bump

Specifies the amount of the perturbations mapped onto the ripple surface. Adjusting this option can lend a

veined or knobby appearance to the surface, depending on the value you choose.

Gloss

Specifies the glossiness of the surface.

Noise

Specifies the amount of grain or imperfections on the surface.

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 actually
composed of four solid-color circles blended together, each with an effect point as its center.

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 clip’s Opacity value.

Blending Mode

The blending mode to use in combining the gradient with the clip.
