Multi-Hyphenate Workflow

Directors who also write and star in films (such as Ben Affleck in high-tension thrillers like Animals or The Town) require immediate spatial and narrative coherence. This tool coordinates screenwriting dramatic tension directly with camera blocking and physical sightlines.

The 180-Degree Line Rule

The dashed line connects primary interacting actors. Cameras placed on the opposite side will invert screen direction (left-to-right eye-traces flip), disorienting audiences unless deliberately broken for psychological effect. The engine alerts you immediately if a camera crosses the line.

Camera Coverage & Focal Lengths

Adjust camera positions and rotations. Wider focal lengths (28mm-35mm) exaggerate physical separation and claustrophobia; longer portrait lenses (85mm-135mm) isolate actors and compress emotional distance during turning points.
