The purpose of editing is to allow films to flow coherently without confusing viewers. Before editing, films were static shots but editing enables more creative storytelling. Analog editing involved physically cutting film, while digital editing is now standard via software like Premiere Pro. Continuity editing shows a logical sequence of events, while discontinuity editing may use techniques like flashbacks. Montage editing condenses many short shots to show the passage of time. Match cuts emphasize similarities between shots, and cross cuts imply simultaneous events. Jump cuts abruptly transition between scenes.
