Scene Consistency Guide

Why scenes drift

Text alone is a weak representation of a complex room or street. If every shot regenerates the environment from scratch, doors, windows, furniture, horizon lines, and light sources will move. A spatial master gives each shot the same physical reference.

Four spatial locking methods

Four ways to lock a space:
1. Nine-panel scene grid
2. Top-down plan with multiple camera positions
3. 360-degree orbit screenshots
4. 720 panorama with perspective correction

Use a grid for dialogue scenes, a top-down plan for complex interiors, orbit screenshots when you need quick angle coverage, and a corrected panorama when the camera needs broad freedom.

Continuity rules

Scene continuity rules:
1. Build the space before shooting the story
2. Establish one spatial master before splitting shots
3. Submit character and environment references separately
4. Add bridge shots when moving from exterior to interior
5. Correct panorama perspective before using it as a reference

Recommended sequence

1. Find one ideal environment reference
2. Reverse-engineer the full spatial description
3. Generate a spatial master: grid, plan, or panorama
4. Extract several camera positions from that master
5. Place the character into those positions
6. Generate final motion shots last

Keep environment and character references separate when possible. The environment controls geometry and light; the character reference controls appearance, clothing, and scale.

Common fixes

Background proportions look wrong: correct perspective with image-to-image first
Character position drifts: mark the position on the base image
Light direction changes: return to the spatial master and unify the source
Exterior-to-interior cut feels abrupt: add a doorway, corridor, or push-through bridge shot

Preserve good composition or lighting from a failed take when possible. Repair the specific spatial or action problem instead of regenerating the entire sequence.

Pre-generation checklist

• Is there a spatial master?
• Is the light direction shared across shots?
• Are character positions explicit?
• Do all shots obey the same physical layout?
• Do exterior-to-interior or doorway transitions need bridge shots?
