Ripple
The Ripple effect adds spaced ripples to the image's surface (like ripples on the surface of a pond). You can change the number of added ripples and the speed of their movement.
In the Properties Area of the Video Effect window you can change the effect propertieschange the effect properties.
The properties of the Ripple effect available for setting are Omega (number of ripple rings), Offset (objects offset along the ripple rings) and Speed (ripple motion speed) values. The positive speed values let the ripples travel outward from the center point, the negative values make the ripples move toward the center point.
In the figures below you can see the video picture before and after applying the Ripple effect:
