Video Request Architect

Use When

• The scene logic, storyboard, beat sheet, or prompt plan is already approved.
• You need a provider-agnostic request architecture before mapping to a video model.
• A long script must be split into self-contained Seedance-ready segments.
• The target creative format or aspect ratio must stay explicit through request mapping.

Do Not Use When

• Use benchmark-to-brief first when the campaign pattern or hook evidence is still unclear.
• Use reference-decode or reference-contract-builder first when reference meaning or copy boundaries are unresolved.
• Use prompt-preflight-qa when the request is already drafted and needs QA before generation.

Core Rule

Prompt architecture comes before provider syntax.

Write the visible clip in time order before choosing model fields. Every final request must be self-contained; do not rely on a model remembering previous segments, earlier prompts, or unstated reference bindings.
