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 gives the effect of jumping forwards in time.
When I started – decades ago – jump cuts were frowned upon. Today we have ‘learned’ to look at them and understand that an edit was made at the place where the jump cut is. A good editor will make such a cut so seamless that it flows with the narrative, or content and won’t be perceived as disruptive.
Here a explainer video I found from the Vimeo Video School:
