The document discusses the historical development of editing techniques in film. It begins in the 1890s when the Lumiere Brothers filmed single shot recordings lasting 1-2 minutes with no editing. Georges Melies then began connecting shots to create episodic films. In 1903, Edwin Porter used editing to create parallel action in films like The Great Train Robbery. D.W. Griffith further advanced editing with his use of shot variation in Birth of a Nation in 1915. Continuity editing was then developed to make cuts invisible. Meanwhile, Russian filmmakers like Eisenstein pioneered intellectual montage using collision of shots to imply meanings not contained in the shots themselves.
