4-Color Gradient effect
The 4-Color Gradient effect produces a four-color gradient. Each color is controlled by one of four individual effect
points, which can be animated. Use 4-Color Gradient to create color backgrounds, mix color palettes, and generate
color gradients.
This effect works with 8-bpc and 16-bpc color.

Adjust the following controls for 4-Color Gradient:
Points
Adjusts the positioning of each color within the four-color gradient, based on (x,y) coordinate values.
Colors
Specifies the RGB color values for each of the four points. Color 1 sets the color of Point 1, Color 2 sets the
color of Point 2, and so on.
Blend
Specifies the blending of the gradient. The gradient is actually composed of four circles, each blending with
one another as the result of a calculation between one circle’s radius and that of the other surrounding circles. The
amount of blending depends on the location of the effect points.
Jitter
Specifies the amount of
jitter
(noise) in the gradient when blending is applied. Jitter uses a controlled noise
type to change pixel values in the gradient, in order to reduce banding. The jitter noise affects only those areas where
banding could occur.
Opacity
Specifies the transparency of the gradient. The lower the value, the more transparent the gradient. The
original source layer’s opacity value represents 100% opacity in the effect.
Blending Mode
Specifies how the gradient colors interact with the original layer colors.
Advanced Lightning effect (Pro only)
The Advanced Lightning effect creates simulations of electrical discharges. Unlike the Lightning effect, Advanced
Lightning doesn't self-animate and includes the Alpha Obstacle feature, which lets you move the lightning around
designated objects in the frame. Use Advanced Lightning when you want more control over the lightning than is
available using the Lightning effect.
This effect works with 8-bpc color.
