Ripple (PB only)
This effect creates the appearance of ripples in a specified layer, moving away from a
center point in concentric circles. The effect is similar to dropping a stone in a pond. You
can also specify that ripples move toward the center point. Animate ripples at a constant
speed using the Wave Speed control, which does not require keyframes for animation.
Animate ripples at varying speeds by creating keyframes for the Ripple Phase control.

Smear
Using Smear, you define an area within an image and then move that area to a new
location, stretching, or smearing, the surrounding part of the image with it. Create masks
to define the area you want to distort.
