ADOBE PREMIERE PRO CS3 346 User Guide Evolution Animating this setting results in changes of the roughness over time. Note: Although the Evolution value is set in units called revolutions, it's important to realize that these revolutions are progressive. The evolution state continues to progress infinitely at each new value. Use the Cycle Evolution option to return the Evolution setting to its original state at each revolution. Evolution Options Provide controls that render the effect for one short cycle and then loop it for the duration of your clip. Use these controls to prerender the roughen elements into loops, and thus speed up rendering time. • Cycle Evolution Creates a loop that forces the evolution state to return to its starting point. • Cycle The number of revolutions of the Evolution setting that the fractal cycles through before it repeats. The timing of the Evolution cycles is determined by the amount of time between Evolution keyframes. Note: The Cycle control affects only the state of the fractal, not geometrics or other controls, so you can get different results with different Size or Offset settings. • Random Seed Specifies a value from which to generate the fractal noise. Animating this property results in flashing from one set of fractal shapes to another within the same fractal type. For smooth transition of the fractal noise, use the Evolution control. Note: Create new roughness animations by reusing previously created Evolution cycles and changing only the Random Seed value. Using a new Random Seed value alters the noise pattern without disturbing the evolution animation. Solarize effect The Solarize effect creates a blend between a negative and positive image, causing the image to appear to have a halo. This effect is analogous to briefly exposing a print to light during developing. Strobe Light effect The Strobe Light effect performs an arithmetic operation on a clip or makes the clip transparent at periodic or random intervals. For example, every five seconds the clip could become completely transparent for one-tenth of a second, or a clip's colors could invert at random intervals. Strobe Color The color of the strobe light. Blend With Original The effect's transparency. The result of the effect is blended with the original image, with the effect result composited on top. The higher you set this value, the less the effect affects the clip. For example, if you set this value to 100%, the effect has no visible result on the clip; if you set this value to 0%, the original image doesn't show through. Strobe Duration (Secs) How long, in seconds, each strobe lasts. Strobe Period (Secs) The time, in seconds, between the start of subsequent strobes. Random Strobe Probability The probability that the strobe operation will apply to any given frame. Strobe Choose Makes Layer Transparent for each strobe to make the clip transparent. Choose Operates On Color Only to use the operation specified by Strobe Operator. Strobe Operator The operation to use for each strobe. April 1, 2008
