Jump cut

A jump cut is a cut in film editing in which two sequential shots of the same subject are taken from camera positions that vary only slightly. This type of edit causes the subject of the shots to appear to "jump" position in a discontinuous way. 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. Jump cuts, in contrast, draw attention to the constructed nature of the film. Although the term is sometimes used in a loose way, a cut between two different subjects is not a true jump cut, no matter how jarring.

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 (e.g., from a medium shot to a close up). 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 (Spatial Jump Cuts), they can also be created by removing a middle section of one continuously-filmed shot (Temporal Jump Cuts).

George Méliès 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. Contemporary use of the jump cut stems from its appearance in the work of Jean-Luc Godard (at the suggestion of Jean-Pierre Melville) and other filmmakers of the French New Wave of the late 1950s and 1960s. In Godard's ground-breaking Breathless (1960), for example, he cut together shots of Jean Seberg riding in a convertible (see right) in such a way that the discontinuity between shots is emphasized and its jarring effect deliberate. In the screen shots to the right, the first image comes from the very end of one shot and the second is the very beginning of the next shot — thus emphasizing the gap in action between the two (when Seberg picked up the mirror). Recently the jump cut has been used in films like Snatch, from Guy Ritchie, and Run Lola Run, from Tom Tykwer. It is frequently used in TV editing, in documentaries produced by Discovery Channel and National Geographic Channel (NatGeo), for example.

The jump cut has sometimes served a political use in film. It has been used as an alienating Brechtian technique (the Verfremdungseffekt) 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.

In informal contexts the term jump cut is sometimes used to describe any abrupt and noticeable edit cut in a film. However, technically this is an incorrect usage of the term. A famous example of this is found at the end of the "Dawn of Man" sequence in the film 2001: A Space Odyssey. A primitive ape discovers the use of bones as a weapon and throws the bone into the air. When the bone reaches its highest point, the shot cuts to that of a similarly-shaped space station in orbit above the earth. This edit has been described as a jump cut, including on the box of the DVD release of the film, but it is more correctly a graphic match because the viewer is meant to see the similarity between the bone and the space craft and not the discontinuity between the two shots.

The jump cut was an uncommon technique for television until shows like Homicide: Life on the Street popularized it on the small screen in the 1990s. It was also famously used in a campaign commercial for US President Ronald Reagan's successful 1984 reelection bid.

Jump cuts are sometimes used to show a nervous searching scene as is done in the 2009 sci-fi film Moon where the protagonist is looking for a secret room on a space station and District 9 where Wikus searches for illegal objects in the house of Christopher's friend.

Reflections:
I am not intending to use any jump cuts in the film at the moment but I will still leave it open as a possibility.
