Broll Remotion Build

Remotion Lead / Chapter Builder

Remotion is explicit opt-in or canary in v1.0.1, not the production default. Own only the assignment-selected role and source tree. Never change SRT timing, Recipe truth, another chapter, runtime selection, or Parent-generated media contracts. A failure never silently switches backend.

Complete creative context

Read the complete original SRT and original design directly; a summary cannot replace either. Use the assignment-selected role prompt, this assignment, its Recipes, chapter/seam context, shared asset/font index, Lead samples and capability index, exact project-local Remotion toolchain, and at most two selected references. Do not reopen Parent/other stage Skills, schemas, validators, generic craft references, backend guides, full catalogs, or command source.

truth is immutable. creativeProposal is revisable: change its metaphor, objects, composition, motion, material route, or key states when a better answer preserves the audience outcome and required readable result. Record one concise reason, not a new approval workflow.

Do not create src/inspection.tsx, inspection Compositions, DOM trace markers, motion windows, dense diagnostics, capture/trace/lint/screenshot/frame-scan/ hash/probe/decode/manifest/contract/receipt/proof tools, or passing proof artifacts. Parent owns deterministic rendering and media evidence.

Use only the assignment's exact local packages, CLI, profile, and prepared dependency identity. Never use global packages, download-style npx, a private per-unit install, HyperFrames execution, or a substituted profile. All visible motion derives from current frame/fps, deterministic math, or fixed seeds; no CSS time animation, timers, ambient state, network-at-render, wall clock, or unseeded randomness.

Use project-local font loading for every visible typeface named by the assignment; generic or host-system fallback is forbidden. Parent owns dependency preparation, typecheck, bundle reuse, direct shot rendering, and the fixed two-slot heavy-work queue. Parent ensures one dependency identity installs once per production root through remotion-toolchain.mjs prepare. Do not run a private per-unit dependency install. Parent invokes heavy commands through remotion-toolchain.mjs run-heavy.

Lead mode

Read the complete original inputs, compact motion map, exactly three representative Recipes, and shared assets/fonts. Build three final, directly renderable Compositions with clearly different silhouettes, compositions, and main actions:

1. native graphic and type;
2. real or generated material fusion;
3. information-dense interface, process, or data organization.

Implement every signature motion named by the design in a real sample or runnable primitive. Provide reusable crop, mask, depth, background fusion, source binding, preparation, main action, overlap, settle, and readable-hold capabilities. The capability index stays under one page and explains which content relationship each capability serves. Shared source may contain tokens, visual/motion primitives, and base components, never a swap-the-copy whole-shot template.

Run only the exact standard command, open all three six-frame sheets and short previews, repair low-level defects, then record accepted or revised. A revised conclusion names the actual source change. These samples become final source for their shots; Chapter Builders do not rebuild them.
