Evolution controls for the Fractal Noise effect

Adjust the following controls for the Fractal Noise effect:

Evolution

Specifies evolution cycles.

Instead of animating Evolution over the entire composition, save rendering time by pre-rendering and looping one short evolution cycle for the duration you want.(See Creating a seamless loop.)

• Cycle Evolution creates a cycle of evolution that loops over the set amount of time. It forces the evolution state to return to its starting point, creating a smooth progressive cycle, a nonrepeating cycle, or a loop segment.
• Cycle (in Revolutions) specifies the number of revolutions that the fractal noise cycles through before it repeats. The speed of these Evolution cycles is determined by the amount of time between Evolution keyframes. This option affects only the evolution of the fractal, not Transform or other controls. For example, if you view two identical states of a fractal with different Size or Offset settings, they do not appear the same.
• Random Seed sets a unique random value from which to generate the noise. Animating the Random Seed results in flashing from one set of fractal shapes to another (within that fractal type). For smooth transition of the fractal shapes use the Evolution option.

To ensure that a cycle completes full revolutions, choose a Cycle value that either matches or is evenly divisible by the number of revolutions set for Evolution.

Note: Cycle is available only when Cycle Evolution is selected.

You can easily create new fractal noise animations by reusing previously created Evolution cycles and changing only the Random Seed value. Typing a new Random Seed value alters the noise pattern without disturbing the evolution animation.

Opacity

Specifies the opacity of the noise layer.

Blending Mode

Specifies an operation between the fractal noise and the original layer. These Blending Modes are identical to the ones in the After Effects Modes column, with the following three exceptions:

• None renders the fractal only and does not composite with the original layer.
• Hue renders the fractal as hue values instead of grayscale. The Saturation and Lightness of the original layer are maintained. If the original layer is grayscale, nothing happens.
• Saturation renders the fractal as saturation values instead of grayscale. The Hue and Lightness of the original layer are maintained. If the original layer is grayscale, nothing happens.
