The document discusses the history of film editing from its beginnings to modern times. It describes how the Lumiere brothers captured early motion pictures in the late 1800s without any editing. The first film editor was the Moviola, invented in 1924, which allowed editors to precisely determine cut points. Russian cinema developed influential editing techniques like montage under Sergei Eisenstein. D.W. Griffith was an early American director who advanced editing with groundbreaking films like The Birth of a Nation in the early 1900s.
