remotion-motion-language
Owns "how the brand moves". Outputs a BrandMotion block, validated against remotion-studio/src/motion/index.ts.
Triggers
- BrandConfig has no
motion block, or motion.signature is unset.
- A composition feels generic — designer flags "needs distinctive motion".
- New composition type is added that needs to inherit brand motion.
Inputs
brandSlug- Tone descriptors from
BrandConfig.voice.tone (authoritative / urgent / warm / etc.)
- Audience from
BrandConfig.audience

Method
- Map tone → signature (table above).
- Set
durations.fast / base / slow per signature row.
- Set
transitionFrames = round(durations.base × 0.7).
- Set easing trio:
in (expo-out by default), out (expo-in), inOut (expo-in-out).
- Validate the signature is supported by
signatureEntry() — if not, fall back to rise and note in PR.
Output
A BrandMotion object for direct insertion into BrandConfig.motion. Plus a 2-3 line rationale comment explaining why this signature was chosen for this brand.
Boundaries
- Never use
pulse (overshoot) for authoritative brands — feels frivolous.
- Never use
whip for reassuring brands — too aggressive.
- Never extend the catalogue without also adding a case to
signatureEntry() — runtime would fall through to identity.
Hands off to
remotion-brand-codify writes the result; remotion-composition-builder reads it via cfg.motion.
1---2name: remotion-motion-language3description: Designs a brand-specific motion vocabulary — easing curves, default scene durations, signature entry/exit, transition frames. Each brand gets one signature move (rise / sweep / pulse / iris / whip) that recurs across compositions to build motion-recognition.
