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. 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.
