# Remotion Video Toolkit

Write React components, get real MP4 videos. This skill teaches your AI agent how to build with Remotion — from a first animation to a production rendering pipeline.

29 rules. Every major Remotion feature covered.

---

## What you can build with this

**Personalized video at scale**
Feed user data as JSON props, render a unique video per user. Think Spotify Wrapped, GitHub Unwrapped, onboarding walkthroughs — one template, thousands of outputs.

**Automated social media clips**
Pull live data (stats, leaderboards, product metrics) and render daily or weekly video posts without anyone touching a timeline editor.

**Dynamic ads and marketing videos**
Swap in customer name, product image, pricing. Same template, infinite variations. Render server-side via API or Lambda.

**Animated data visualizations**
Turn dashboards and KPI reports into shareable video clips with animated charts and transitions.

**TikTok and Reels captions**
Transcribe audio, display word-by-word highlighted subtitles, export ready for upload.

**Product showcase videos**
Auto-generate from your database — images, specs, pricing — straight to MP4.

**Educational and explainer content**
Animated course materials, certificate videos, step-by-step walkthroughs — all driven by code.

**Video generation as a service**
Expose rendering as an HTTP endpoint. Your app sends JSON, gets back a video file.

## Requirements

- **Node.js** 18+
- **React** 18+ (Remotion renders React components frame-by-frame)
- **Remotion** — scaffold with `npx create-video@latest`
- **FFmpeg** — ships with `@remotion/renderer`, no separate install needed
- For serverless rendering: **AWS** account (Lambda) or **GCP** account (Cloud Run)
