Edge Color The color to apply to the edge for Rusty Color or Roughen Color, or to the fill for Photocopy Color.
Border How far, in pixels, the effect extends inward from the edge of the alpha channel.
Edge Sharpness Low values create softer edges. High values create sharper edges.
Fractal Influence The amount of roughening.
Scale The scale of the fractal used to calculate the roughness.
Stretch Width or Height The width or height of the fractal used to calculate the roughness.
Offset (Turbulence) Determines the portion of the fractal shape that is used to create the roughness.
Complexity Determines the level of detail in the roughness.
Note: Increasing complexity results in longer rendering times. Reduce the Scale value rather than increasing Complexity to achieve similar
results.
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 Evolution Options provide controls that render the effect for one short cycle and then loop it for the duration of your layer. Use
these controls to pre-render your roughen elements into loops, and thus speed up rendering time. Use the following controls to create a smooth,
progressive, nonrepeating loop:
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 amount of time between
Evolution keyframes determines the timing of the Evolution cycles.
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 roughness texture. Animating this property results in flashing from one set of
fractal shapes to another within the same fractal type. For smooth transition of the roughness, 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.
Scatter effect
The Scatter effect scatters the pixels in a layer, creating a blurry or smeared appearance. Without changing the color of each individual pixel, the
Scatter effect redistributes the pixels randomly, but in the same general area as their original positions.
This effect works with 8-bpc and 16-bpc color.
Original (left), and with effect applied (right)
Grain The direction in which to scatter the pixels—horizontally or vertically. Select None to scatter pixels in all directions.
Scatter Randomness Specifies whether scattering changes at each frame. To animate scattering without keyframes or expressions, select the
Randomize Every Frame option.
Strobe Light effect
Strobe Light effect applied
The Strobe Light effect performs an arithmetic operation on a layer or makes the layer transparent at periodic or random intervals. For example,
every 5 seconds the layer could become completely transparent for one-tenth of a second, or the colors of a layer could invert at random intervals.
This effect works with 8-bpc color.
Strobe Color The color of the strobe light.
Blend With Original The transparency of the effect. The result of the effect is blended with the original image, with the effect result composited on
