Remotion Video

Creates production-grade videos using Remotion — a React framework where video is code. Every frame is a React component. Animations use spring physics and frame-based interpolation.

Why Remotion

Remotion treats video as a React application. Each frame is a pure function of time — given frame N and total frames F, your component renders deterministically. This means:

• **Component composition**: Nest scenes, reuse components, apply CSS.
• **Spring physics**: `spring()` gives natural motion without hand-tweaking cubic beziers.
• **Asset pipeline**: Import images, audio, video — the same way you import in React.
• **Iterative workflow**: Edit code → hot-reload preview → render final. The `.tsx` file IS the editable intermediate.
• **Data-driven at scale**: Render thousands of personalized videos by passing different props to the same composition.

Workflow

Scaffold → Compose → Preview → Iterate → Render

1. **Scaffold** the project (once per video project) 2. **Interpret** the user's concept — choose the right template and rule files 3. **Compose** React components for each scene 4. **Preview** in Remotion Studio (`npm run dev`) 5. **Iterate** based on user feedback 6. **Render** final video via `scripts/render.sh`

Step 0: Ensure Dependencies

Node.js 18+ is required. Check before scaffolding:

node --version   # Must be >= 18.0.0
npm --version

If Node.js is not available, inform the user — Remotion cannot run without it.

Step 1: Scaffold the Project

Run `scripts/scaffold_project.sh` to create a new Remotion project. The script is idempotent — it detects an existing project and skips re-initialization.

bash scripts/scaffold_project.sh my-video-project
cd my-video-project
npm run dev   # Opens Remotion Studio at localhost:3000

Step 2: Interpret the Concept

Determine the best approach. Read the relevant rule file for detailed patterns.

| Content type | Rule file | Template | | ----------------------------------- | ----------------------- | ---------------- | | Explainer / educational | fundamentals.md | explainer.tsx | | Product demo / marketing | animations.md | product-demo.tsx | | Data visualization / animated chart | charts.md | data-viz.tsx | | Video with voiceover / narration | audio.md + subtitles.md | explainer.tsx | | Social media clip (short, looping) | animations.md | product-demo.tsx | | 3D scene / abstract motion graphics | three-d.md | (custom) | | Personalized / batch generation | data-driven.md | any | | Video with embedded media | media.md | any |

Step 3: Compose the Components

Core rules for writing Remotion components:

• **One composition per video**: `registerRoot` points to one root composition.
• **Sequences for timing**: Use `<Sequence from={30} durationInFrames={60}>` to place scenes at specific frames.
• **AbsoluteFill for layering**: Use `<AbsoluteFill>` as the base for any full-
