A jump cut is a cut in film editing in which a single continuous sequential shot of a subject is broken into two parts, with a piece of footage being removed in order to render the effect of jumping forwards in time. Camera positions of the subject in the remaining pieces of footage of the sequence should vary only slightly in order to achieve the effect. It is a manipulation of temporal space using the duration of a single shot, and fracturing the duration to move the audience ahead. This kind of cut abruptly communicates the passing of time as opposed to the more seamless dissolve heavily used in films predating Jean-Luc Godard's Breathless, which made extensive use of jump cuts and popularized the technique during the 1960s. For this reason, jump cuts are considered a violation of classical continuity editing, which aims to give the appearance of continuous time and space in the story-world by de-emphasizing editing, but are sometimes nonetheless used for creative purposes. Jump cuts tend to draw attention to the constructed nature of the film. More than one jump cut is sometimes used in a single sequence. Continuity editing uses a guideline called the "30 degree rule" to avoid jump cuts. The 30 degree rule advises that for consecutive shots to appear seamless, the camera position must vary at least 30 degrees from its previous position. Some schools would call for a change in framing as well. Generally, if the camera position changes less than 30 degrees, the difference between the two shots will not be substantial enough, and the viewer will experience the edit as a jump in the position of the subject that is jarring, and draws attention to itself. Although jump cuts can be created through the editing together of two shots filmed non-continuously, they can also be created by removing a middle section of one continuously filmed shot. Jump cuts can add a sense of speed to the sequence of events.
History
is known as the father of the jump cut as a result of having discovered it accidentally, and then using it to simulate magical tricks; however, he tried to make the cut appear seamless to complement his illusions. The effect was used in the early film The Tempest when Ariel magically disappears and reappears. Dziga Vertof's avant-garde Russian film Man With a Movie Camera is almost entirely composed of jump cuts. Contemporary use of the jump cut largely stems from its appearance in the work of Jean-Luc Godard and other filmmakers of the French New Wave of the late 1950s and 1960s. In Godard's ground-breaking Breathless, for example, he cut together shots of Jean Seberg riding in a convertible in such a way that the discontinuity between shots is emphasized and its jarring effect deliberate. In the clip above the scene abruptly changes perspective - emphasizing a gap in action. Recently the jump cut has been used in films like Snatch, by Guy Ritchie, and Run Lola Run, by Tom Tykwer. It is frequently used in TV editing, in documentaries produced by Discovery Channel and National Geographic Channel, for example. It is noticeable in Universal Monsters films and music videos.
Notable examples
The jump cut has sometimes served a political use in film. It has been used as an alienating Brechtian technique that makes the audience aware of the unreality of the film experience, in order to focus the audience's attention on the political message of a film rather than the drama or emotion of the narrative—as may be observed in some segments of Sergei Eisenstein's The Battleship Potemkin. It was also used in Alexander Dovzhenko's Arsenal, where a close-up shot of a character's face cuts closer and closer a total of nine times. Mark Cousins comments that this "fragmentation captured his indecision... and confusion", adding that "Although the effect jars, the idea of visual conflict was central to Soviet montage cinema of that time". Jump cuts are sometimes used to show a nervous searching scene, as is done in the 2009science fiction filmMoon in which the protagonist, Sam Bell, is looking for a secret room on a moon base, and District 9 in which the protagonist, Wikus, searches for illegal objects in the house of Christopher's friend. Jump cuts plays a significant and disorienting role in a scene of Joel and Ethan Coen’s A Serious Man, in which shots of Rabbi Nachtner and Larry Gopnik having a conversation in the Rabbi’s office are interspersed with shots depicting another meeting that Nachtner previously had with a different person in the same office. In television, Rowan & Martin's Laugh-In editor Arthur Schneider won an Emmy Award in 1968 for his pioneering use of the jump cut. Jump cutting remained an uncommon TV technique until shows like popularized it on the small screen in the 1990s. The well-remembered music video for "Everybody Have Fun Tonight" has a jump cut for virtually every frame. Other uses of the jump cuts include Vincent Gallo's short "Flying Christ" in which various shots of "Christ" jumping are cut together as he is in mid jump, creating the illusion of flight, and in many vlogs online, as popularized by the show with zefrank. British comedian Russell Kane has produced a series of comic, satirical videos, named "Kaneings", in response to current events. These make extensive use of jump cut-style editing.
Confusion with other transitions
Vernacular use of the term jump cut can describe any abrupt or noticeable edit in a film. However, technically, many such over-broad usages are incorrect. In particular, a cut between two different subjects is not a true jump cut, no matter how jarring. A jump cut usually involves a jump through narrative time or an "elliptical" edit, wherein a shot of continuous action is broken up with a sudden cut.
