Screen To Video Bridge

Use this skill when the user wants to turn a scene, ad beat, or adaptation fragment into a screen_to_video_brief.

Typical cases:

• bridge a scene into a Sora / Seedance / generic video-generation brief;
• prepare a previz-facing visual brief without flattening the original screenplay;
• split a scene into clip-sized units with invariants and control intensity;
• preserve dramatic intent while adapting to short clip duration and execution limits.

Workflow

1. Identify the source container: scene draft, scene card, ad beat, or adaptation fragment.
2. Preserve source spans or evidence anchors whenever possible.
3. Extract the dramatic function and minimum non-negotiable beats.
4. Decide whether the work should stay one clip or be split into a clip chain.
5. For long material, batch by structure first, not by arbitrary chunk size.
6. Choose one main action and one main camera logic per clip.
7. Return a layered brief with invariants, avoid rules, grounded visible assets, and runtime-specific notes only when they materially matter.

Output Contract

• screen_to_video_brief: a bounded bridge document with source-scene intent, clip structure, shot/action logic, invariants, avoid items, and runtime-facing notes.
• The brief should not replace the screenplay.
• Tool details belong only when they change execution decisions.

Posture-Adaptive Guidance

When certainty = lost: Ask: "What is the single most important visual moment in this material — the one image that cannot be lost in translation?" One anchor image is enough to build the brief. Do not ask for a full source summary.

When source = construct: Primary activation context. Apply the full workflow: identify source container → preserve source spans → extract dramatic function → decide clip vs. clip chain → choose main action and camera logic per clip → return layered brief with invariants and avoid rules.

When certainty = certain: Apply full output contract strictly. The brief must not replace the screenplay. Tool-specific details belong only when they change execution decisions materially.

When focus = world: Visual grounding in world-specific assets (locations, objects, light qualities) is the primary concern. Invariants should include world-consistent visual markers, not just character appearance.

When focus = audience: The downstream execution audience — model prompt consumer or previz team — is the real audience here. Calibrate specificity to what they need to make decisions, not to what is interesting about the source.
