Very fast panning movement.
An extremely fast movement of the camera from side to side, which briefly causes the image to blur into a set of indistinct horizontal streaks. Often an imperceptible cut will join two whip pans to create a trick transition between scenes.
AKA: Whip-pan An extremely fast pan, incorporating much motion blur. The term refers to the "whipping" action that the camera operator uses to move the camera.
(swish pan) Extremely rapid pan that creates a blur on the screen. Two such pans in the same direction, edited together -- one moving from, the other moving toward a stationary shot -- can convey the passage of time or a change of location.
A whip pan is a type of pan shot in which the camera moves sideways so quickly that the picture blurs into indistinct streaks. It is commonly used as a transition between shots, and can indicate the passage of time and/or a frenetic pace of action.
