There are several key techniques involved in editing video and film. Editing pieces together raw footage in a logical order to tell a story or convey a message. Some essential techniques include continuity editing to maintain consistency between scenes, match cuts to smoothly transition between related actions, and shot reverse shot to alternate between two characters in a conversation. The history of editing began with early films being single static shots but evolved with pioneers like Edwin Porter and D.W. Griffith developing new techniques like cutting between multiple storylines. Analog editing involved physically cutting and splicing tape, while digital editing now uses software.
