effect is Regular Show. The Red Green Show also makes frequent use of this wipe style, featuring an animated roll of duct tape, and accompanied by the loud "yanking tape off a roll" sound effect. The most common uses of the wipe effect is the invisible wipe where a camera follows a person into another room by tracking parallel to the actor. As the wall passes in front of the camera, the editor has the option of using a wipe to be able to choose any other matching take of the same scene. It is also commonly used in quick camera pans in action sequences, to make a cut invisible. Such wipes can be impossible to see in the finished film. A good example of this wipe can be seen in the movie Das Boot when director Wolfgang Petersen uses it to pan between two occupied U-boat pens, even though they had only one U-boat for filming. Some extremely effective (and expensive) wipes were used in the otherwise very low-budget Laurel and Hardy short film Thicker than Water. For each of the scene changes in this film, either Laurel or Hardy or both of them would seize a curtain or some other object at the edge of the frame and move it across the screen. The opening frames of the next scene were optically printed onto this object, so that—when the object entirely filled the screen—the movie had "wiped" the last shot of the previous scene and begun the first shot of the next. The earliest known example of a wipe was George Albert Smith's film 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. Since at least the 1980s, the American game show The Price is Right has made extensive use of wipes, usually from contestants to prizes. In the early-to-mid 1980s, an iris slow was used twice during the opening sequence, transitioning from the shot of the host entrance to the camera panning down from the studio lights, and then from that camera shot to one of the host. Around 1987, this was changed to a star wipe, which the show would end up using for years until 2010. Film editing Cinematic techniques Articles containing video clips
