This document summarizes the evolution of film editing techniques from the early silent films of the Lumiere Brothers and Georges Melies to the developments of D.W. Griffith and later Soviet filmmakers. It discusses how Griffith expanded on the work of Edwin Porter to use parallel editing and shot variation to build drama. Pudovkin and Kuleshov then formulated the theory of constructive editing where each shot makes a specific point and meaning can come from shot juxtaposition. Eisenstein further developed intellectual montage using film to directly comment on ideas rather than just tell a story.
