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.
INDEX
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.
