ADOBE PREMIERE PRO CS3 326 User Guide See also "Ripple (Circular) effect (Windows only)" on page 326 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. 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. April 1, 2008
