A wipe is a type of film transition where one shot replaces another by travelling from one side of the frame to another or with a special shape. If the wipe proceeds from two opposite edges of the screen toward the center or vice versa, it is known as a barn door wipe (named for its similarity to a pair of doors opening or closing).
The following are some specific styles of wipes:
The earliest known example of a wipe was George Albert Smith's Mary Jane's Mishap of 1903.
George Lucas made sweeping use of wipes in his Star Wars films, inspired by a similar use of wipes by Akira Kurosawa.
