Film editing has been called "The Music of Light", "Sculpture in Time", and "The Mobile Architecture of Film". But what is montage? What role does film editing play in the art of cinema? How has it evolved, what does it reflect in the world around us, and where is it taking us next?

The documentary film Edge Codes addresses these most fundamental of cinematic questions, and elevates awareness and appreciation of the history, art, craft, and technology of motion picture editing. In combining film excerpts and interviews with eminent film editors, directors, and academics, Edge Codes demonstrates with its own style the very principles and techniques it examines.

Edge Codes delivers an entertaining and informative exploration of the motion picture's "visual language": its vocabulary of shots and sequences, its grammar of image assembly, and its evolution as a living, changing, global language.
