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 forward 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.
