The Editing Process: Assembly to Picture Lock
Editing is where the film is re-created from the raw material of production. All the careful shooting, design, and performance is assembled, shaped, and cut until the story reaches its final form. The editing process has three major stages: Assembly cut (also called the rough cut or editor's cut) — the editor assembles all usable footage in story order, including every take that might work, at roughly correct length. An assembly cut is almost always 2–3 times longer than the final film. It is an organizational tool, not a storytelling one — it reveals what exists and what is missing. First cut (or fine cut) — the director and editor work together through the assembly, making structural decisions: which takes to use, which scenes to cut entirely (often scenes that were important to shoot but are not needed in the final film), where to begin and end scenes, how to pace action sequences. The first cut approximates the final film's structure and length. Picture lock — the final, approved version of the film's edit, with every cut in its exact final position. After picture lock, all other post-production departments (visual effects, color grading, sound design, music) complete their work. Any change after picture lock requires a 'change list' that triggers updates across all post-production work. Editor Walter Murch's six criteria for a cut, in order of importance: Emotion (does the cut serve the emotional experience?), Story (does it advance the narrative?), Rhythm (is it rhythmically right?), Eye-trace (where is the viewer's eye at the cut point?), Two-dimensional plane (is the screen consistent?), Three-dimensional space (does the geography make sense?). Murch argues that cuts can violate the lower criteria (3D space continuity, 2D plane) if they serve the higher ones (emotion, story). An emotionally right cut that technically violates continuity is usually more successful than a technically perfect cut that is emotionally wrong.
