This document discusses the history of editing techniques from the earliest moving pictures to modern cinema. It covers pioneers like the Lumiere Brothers, George Melies, D.W. Griffiths, Fritz Lang, and Charlie Chaplin. Each introduced new techniques, such as looped footage, stop tricks, splicing, fades, and dissolves. The document also explains editor Walter Murch's "Rule of Six" which outlines the ideal percentages of edit types for rhythm, eyetrace, emotion, continuity/story, and the 180-degree and 360-degree rules. Emotion should account for 51% of edits, with continuity/story at 23% and rhythm at 10%, according to Murch's theory.
