Effects and transitions
Last updated 11/6/2011
Ripple Center Specifies the X and Y location of the ripple center. You can also change this property 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.
Generate effects
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.
Cell Pattern effect
The Cell Pattern effect generates cellular patterns based on cellular noise. Use it to create static or moving background
textures and patterns. The patterns can be used in turn as textured mattes, as transition maps, or as a source for
displacement maps.
Original image (left); Cell Pattern effect creates a displacement map (center), which is used for the Displacement Map effect (right).
Cell Pattern The cell pattern to use. HQ denotes high-quality patterns that render with more definition than their
unmarked counterparts. Mixed Crystals is available only as a high-quality option.
Note: The Static Plates option is identical in appearance to the Plates option. However, when evolving, the static plates
retain a uniform lightness value, whereas the plates shift the lightness of the cell pattern.
Invert Inverts the cell pattern. Black areas become white, and white areas become black.
