Scatter (PB only)
This 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. You can automatically
animate the Scatter effect over the time range without keyframes by randomizing every
frame.
For more information, see the After Effects product section on Adobe's Web site.
Strobe Light
This effect performs an arithmetic operation on a layer at periodic or random intervals. For
example, every 5 seconds the layer could appear completely white for one-tenth of a
second, or a layer's colors could invert at random intervals. The layer's quality setting does
not affect Strobe Light.
For more information, see the After Effects product section on Adobe's Web site.
Texturize
This effect gives a layer the appearance of having the texture of another layer. For
example, you could make the image of a tree appear as if it had the texture of bricks, and
control the depth of the texture and the apparent light source. At Best quality, the texture
layer is positioned and scaled with subpixel accuracy.
For more information, see the After Effects product section on Adobe's Web site.
Write-on
This effect animates strokes on a layer. For example, you can simulate the writing of
cursive text or create snakelike movement for a stroke. Use this effect to animate the brush
size, color, hardness, and opacity of a stroke. After Effects Production Bundle also includes
the Vector Paint effect, which you can also use to animate strokes. For more information
on Vector Paint, see "About Vector Paint (PB only)" on page 333.
At each keyframe, you can apply a new property value to the current segment of the
stroke, or you can apply the value to the entire stroke. For example, you can make a stroke
become gradually thicker as it is drawn by increasing the stroke's brush size at each
keyframe. You control whether a property is applied to stroke segments or to the entire
stroke using the Paint Time and Brush Time menus.
