Color The color of the nontransparent rectangles.
Opacity The opacity of the colored rectangles.
Blending Mode The blending mode to use to composite the checkerboard pattern on top of the original layer. These blending modes work
identically to the ones in the Timeline panel, except for the default None mode, which renders the checkerboard pattern only.
Circle effect
The Circle effect creates a customizable solid disk or ring.
This effect works with 8-bpc color.
Edge None creates a solid disk. The other options all create rings. Each option corresponds to a different set of properties that determine the
shape and edge treatment of the ring:
Edge Radius The difference between the Edge Radius property and the Radius property is the thickness of the ring.
Thickness The Thickness property sets the thickness of the ring.
Thickness * Radius The product of the Thickness property and the Radius property is the thickness of the ring.
Thickness & Feather * Radius The product of the Thickness property and the Radius property is the thickness of the ring. The product
of the Feather property and the Radius property is the feather of the ring.
Feather The thickness of the feather.
Invert Circle Inverts the matte.
Blending Mode The blending mode used to combine the shape and the original layer. These blending modes behave like the blending modes in
the Timeline panel, except for None, which displays only the shape, without the original layer.
Ellipse effect
The Ellipse effect draws an ellipse.
This effect works with 8-bpc, 16-bpc, and 32-bpc color.
Eyedropper Fill effect
The Eyedropper Fill effect (formerly the Color Picker effect) applies a sampled color to the source layer. This effect is useful for quickly picking a
solid color from a sample point on the original layer or picking a color value from one layer and using blending modes to apply this color to a
second layer.
This effect works with 8-bpc color.
Sample Point The center of the sampled area.
Sample Radius The radius of the sampled area.
Average Pixel Color Which color values are sampled:
Skip Empty Samples the average RGB color values, excluding the color values of transparent pixels.
All Samples the average of all RGB color values, including color values of transparent pixels.
All Premultiplied Samples the average of all RGB color values, premultiplied with the alpha channel.
Including Alpha Samples the average of all RGB color and alpha channel values. This setting results in the sampled color also
containing the average transparency of the sampled pixels.
Maintain Original Alpha Maintains the alpha channel of the original layer. If you choose Including Alpha in the Average Pixel Color menu, the
original alpha is stenciled over the sampled color.
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
top. The higher you set this value, the less the effect affects the layer. For example, if you set this value to 100%, the effect has no visible result on
the layer; if you set this value to 0%, the original image doesn't show through.
Fill effect
The Fill effect fills specified masks with a specified color. If you want to add both a stroke and a fill to a closed path, the order in which you apply
the stroke and fill determines the visible width of the stroke: If the fill is applied before the stroke, the full stroke brush size is visible; if the stroke is
applied before the fill, the fill appears on top of the stroke, obscuring the half of the stroke that falls inside the path.
This effect works with 8-bpc color. In After Effects CS6, this effect works in 32-bit color.
Fractal effect
The Fractal effect renders the Mandelbrot or Julia set, creating colorful textures. When you first apply the effect, the picture you see is the classic
sample of the Mandelbrot set; the set is the area that is colored black. Any pixel outside the set is colorized, depending on how close it is to the
set.
