# Launch Video

**REQUIRED BACKGROUND:** marketing-studio skill. Work in `C:/Projects/animations`.

Produces: `out/<brand>/film/film-vN-scored.mp4` — a bespoke 20-40s film with music,

narration and SFX cues, plus `out/<brand>/launch.mp4` (the scored lock that postkit,

mission-control and review-in-magnetic expect).

**A film is not done without audio, and audio means a voice explaining the product.**

Step 8 is not optional and `node scripts/check-audio.mjs <brand>` must exit 0 before

the word "done". Two postflop cuts shipped silent on 2026-09-01; that is the reason

this line exists.

## Route

Default: a BESPOKE composition at `studio/src/films/<brand>/` (PLAYBOOK "Bespoke

films"; postflop is the worked example). Every product shot is rebuilt native UI

that animates (grids resolving, figures counting, a cursor that clicks), never a

screenshot panel or a screen recording. The LaunchVideo template is the fallback

only when the user asks for the five-act house style explicitly.

## Recipe

1. Direction, before any storyboarding or building: write three one-page directions

with `docs/templates/DIRECTION.md`, kill two with its kill questions, and record the

survivor + its signature move in `out/<brand>/marketing/direction.md`. Skip only if

that file already exists for this version.

2. Shot spec: write `out/<brand>/marketing/film-spec.md` from the direction (copy

postflop's shape: non-negotiables from the brand voice, motion rules judge-motion

scans for, the composition contract, and a timeline table of 6-10 shots with the

beat each one performs and every numeral traceable to brief.json proofPoints).

Narration is planned HERE, per shot, at ~2.6 words/second minus a 150ms breath

between lines; a 28s film carries about 60 spoken words, not 150.

3. Build: `studio/src/films/<brand>/` — timeline.ts (SHOTS, TOTAL, OVERLAP), a ui/

kit of the product's rebuilt pieces, one shots/ShotNN.tsx per timeline row,

Film.tsx sequencing them with overlap handovers, registered in Root.tsx and

scripts/smoke.mjs. Each shot proves itself: render its frame range at

`--scale=0.5`, tile a contact sheet with ffmpeg, Read it, fix, re-render.

4. Gates on the studio: `npx tsc --noEmit -p .` in studio/, `node scripts/judge-motion.mjs

<brand>`, `node scripts/smoke.mjs`.

5. Director loop on the whole film: render `out/<brand>/film/film-vN-preview.mp4` at

half scale, contact-sheet it (fps=2), extract the LAST frame of every shot (must be

static) and the frames around each cut (must overlap, no pop), write your own defect

list, fix, re-render as the NEXT version. Never overwrite a version.

6. Full-res render of the version whose sheets passed: `npx remotion render <Brand>Film

out/<brand>/film/film-vN.mp4`. Read two full-res frames.

7. Audio copy: `scripts/build-<brand>-film-audio.mjs` (copy source of truth: narration

lines with their start second, SFX cues on the landing frames, music prompt) ->

`props/<brand>-film-audio.json`. Written for the ear; every figure from the brief.

8. Score: `node scripts/score-film.mjs <brand> out/<brand>/film/film-vN.mp4`. It refuses

overlapping lines (trim copy in the builder, never the picture) and masters to

TARGET_I, verifying the DELIVERED file. Then `node scripts/verify-cue.mjs` on one

narration window and one bed-only window: the voice must sit clearly above the bed.

9. Lock: copy the scored file to `out/<brand>/launch.mp4`; run

`node scripts/check-audio.mjs <brand>` (exit 0 required) and `node scripts/judge-palette.mjs

<brand> <scored.mp4>`. Deliver per marketing-studio: the user watches the SCORED cut.
