A jump cut is film editing technique in which two sequential shots of the same subject, taken from the same camera positions but a varied slightly. This type of edit can give the audince a really sense of emotion just though the edit. It’s mostly used to give the effect of jumping forwards in time.
In the Jean-Luc Godard’s Breathless, the jump cut was famously first used extensively. For this reason, jump cuts are considered a violation of continuity editing as it draws attention of the constructed editing on the film, it aims to give the appearance of continuous time and space in the story-world.
