A Claude skill

Turn any repo
into a promo video.

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.

It looks like your product

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.

promo-video

The pipeline. Extracts your brand, scaffolds a config-driven Remotion film, writes the script from your features, and renders the deliverables.

ffmpeg

Professional encoding, filters and per-platform presets — yuv420p, faststart, loudness-normalised audio — with version and security discipline.

remotion

Compositions, animation, typed props and rendering — plus the Remotion licence and latest-secure-version guidance built in.

Every format, one timeline

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.
