Infilmmaking, awipe is a type offilm transition where oneshot replaces another[1] by travelling from one side of theframe 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 abarn door wipe (named for its similarity to a pair of doors opening or closing).
The following are some specific styles of wipes:
Aniris slow is a wipe that takes the shape of a growing or shrinking circle. It has been frequently used inanimated short films, such as those in theLooney Tunes andMerrie Melodies cartoon series, to signify the end of a story. When used in this manner, the iris wipe may be centered on a certain focal point and may be used as a device for a "parting shot" joke, afourth wall-breaching wink by a character, or other purposes. Optional graphic (i.e. rips) occasionally overlay it to achieve a certain effect like an iris tearing transition.
Astar wipe is a wipe that takes the shape of a growing or shrinking star and is used to impart a sense of "extra specialness" or "added value". An example of the "star wipe" can be seen in theGuiding Light opening sequences of the 1980s. This convention was considered overused during that time period and is now generally thought to be somewhat out-of-date. The use was parodied inAqua Teen Hunger Force Colon Movie Film for Theaters andThe Simpsons.
Aheart wipe is a wipe that takes the shape of a growing or shrinking heart, and is used to impart a sense of "love" or "friendship". The heart wipe is still used in wedding, graduation, andbar mitzvah videos, among others, as it has now passed from stylistic into the realm of standard convention, though many people consider it tacky.
Amatrix wipe is a patterned transition between two images. The matrix wipe can be various patterns such as a grid, stars, etc.
Aclock wipe is a wipe that sweeps a radius around the center point of the frame to reveal the subsequent shot, like the sweeping hands of an analogclock. Because of this similarity, it is often used to indicate that time has passed between the previous shot and the next shot. One of the TV shows that used the effect isRegular 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 theinvisible 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 movieDas Boot when directorWolfgang Petersen uses it to pan between two occupiedU-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-budgetLaurel and Hardy short filmThicker 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.
Since at least the 1980s, the American game showThe 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.
