Scene Director - Hybrid Pipeline

When To Use

You are translating the hybrid structure into a visual system that keeps the source visible and the support layers under control.

Prerequisites

Layer	Resource	Purpose
Schema	schemas/artifacts/scene_plan.schema.json	Artifact validation
Prior artifacts	state.artifacts["script"]["script"], state.artifacts["idea"]["brief"]	Hybrid structure and source truth
Tools	frame_sampler, scene_detect	Optional source inspection
Playbook	Active style playbook	Layout consistency

Process

1. Keep The Anchor Medium Visible

If the piece is source-led, the source must remain visually primary in the scene plan. Do not hide the anchor behind constant overlays.

2. Reserve Support For Clear Jobs

Use support scenes for:

• chapter transitions,
• clarifying diagrams,
• stat emphasis,
• CTA or summary moments,
• gap-filling inserts.

3. Plan Variant Safety

If the project needs multiple aspect ratios, define where:

• subtitles live,
• speaker labels live,
• chart or code safe zones live,
• crop-sensitive source media becomes unsafe.

4. Use Metadata For Balance Rules

Recommended metadata keys:

• anchor_rules
• support_rules
• safe_zones
• variant_rules
• overlay_density_limits

5. Quality Gate

• the anchor medium stays primary where intended,
• support layers are limited and purposeful,
• aspect-ratio planning is explicit,
• no scene relies on invisible future magic.

Common Pitfalls

• Turning source-led scenes into overlay soup.
• Forgetting variant-safe zones until compose.
• Using generated inserts for every transition.
