FUNHOUSE
Funhouse will warp the image around a particular point.
SLIDERS
X & Y - Define the center of the warp.
Radius - Controls how far the image is stretched.
USAGE
Funhouse can be used to achieve a kind of "fun-house mirror" effect. You can warp a person's face and body to make some very amusing images. It can also be used to make the video look as though it was shot through a "fish-eye" distortion lens.
HEAT
The Heat effect distorts the image by making it appear that ripples of heat are rising from the bottom of the screen.
SLIDERS
Height - Control how high the heat ripples rise.
Intensity - Controls the intensity of the distortion of the heat ripple.
USAGE
This effect is useful in conveying that a scene is happening in hot weather. Heat can be used with the Flame effect for a more realistic hot look.
