A Claude skill
Clapper reads your product's brand — colours, fonts, logo, the copy in your repo — and renders a polished promo film in every social format. Remotion + ffmpeg, multi-aspect, on autopilot.
No templates to wrestle. A brand extractor pulls your CSS custom properties, fonts, logo and app name straight from the codebase; an AI critic loop checks every frame for legibility, contrast and on-brand polish before it ships.
The pipeline. Extracts your brand, scaffolds a config-driven Remotion film, writes the script from your features, and renders the deliverables.
Professional encoding, filters and per-platform presets — yuv420p, faststart, loudness-normalised audio — with version and security discipline.
Compositions, animation, typed props and rendering — plus the Remotion licence and latest-secure-version guidance built in.
Write the film once. A short-edge unit system composes it for every aspect ratio, with per-platform safe areas so nothing hides under the UI.
Install it once, then just ask Claude.
