Remotion - Programmatic Video from React
Create videos entirely in React using Remotion. Each frame is a React component. Write code, render to MP4. No AI model needed - pure programmatic control over every pixel and frame.
When to Use Remotion vs AI Video
| Use Case | Tool |
|---|---|
| Precise animations, branded content, data visualizations | Remotion (this skill) |
| Creative/artistic video from text description | /sw-media:video (AI models) |
| Product demos, marketing, changelogs | Remotion |
| Realistic footage, scenes, landscapes | /sw-media:video |
Workflow
Step 1: Check if Remotion Project Exists
# Check for existing Remotion setup if [ -f "package.json" ] && grep -q '"remotion"' package.json 2>/dev/null; then echo "Remotion project detected" else echo "No Remotion project found - will scaffold one" fi
Step 2: Scaffold Project (If Needed)
If no Remotion project exists, scaffold one:
npx create-video@latest my-video --template blank cd my-video npm install
Or add Remotion to an existing project:
npm install remotion @remotion/cli @remotion/bundler
Step 3: Create Video Composition
Create a React component that defines the video. Key Remotion APIs:
import { useCurrentFrame, useVideoConfig, interpolate, spring, Sequence } from 'remotion';
export const MyComposition: React.FC = () => {
const frame = useCurrentFrame();
const { fps, width, height } = useVideoConfig();
// Animate opacity from 0 to 1 over first 30 frames
const opacity = interpolate(frame, [0, 30], [0, 1], {
extrapolateRight: 'clamp',
});
// Spring animation
const scale = spring({ frame, fps, config: { damping: 100 } });
return (
<div style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
<h1 style={{ opacity, transform: `scale(${scale})`, fontSize: 80 }}>
Hello World
</h1>
</div>
);
};
Register the composition in src/Root.tsx:
import { Composition } from 'remotion';
import { MyComposition } from './MyComposition';
export const RemotionRoot: React.FC = () => {
return (
<Composition
id="MyVideo"
component={MyComposition}
durationInFrames={150} // 5 seconds at 30fps
fps={30}
width={1920}
height={1080}
/>
);
};
Step 4: Preview (Optional)
npx remotion studio # Opens browser at http://localhost:3000 with preview player
Step 5: Render to MP4
npx remotion render src/index.ts MyVideo out/video.mp4
Additional render options:
# Custom resolution npx remotion render src/index.ts MyVideo out/video.mp4 --width 1920 --height 1080 # Lower quality for faster rendering npx remotion render src/index.ts MyVideo out/video.mp4 --quality 80 # Specific frame range npx remotion render src/index.ts MyVideo out/video.mp4 --frames 0-90 # GIF output npx remotion render src/index.ts MyVideo out/animation.gif # PNG sequence npx remotion render src/index.ts MyVideo out/frames --image-format png
Step 6: Verify Output
FILE="out/video.mp4" if [ -f "$FILE" ] && [ -s "$FILE" ]; then file "$FILE" SIZE=$(du -h "$FILE" | cut -f1) echo "Video rendered successfully: $FILE ($SIZE)" else echo "ERROR: Render failed - check console output for errors" fi
Common Animation Patterns
Fade In/Out
const opacity = interpolate(frame, [0, 30], [0, 1], { extrapolateRight: 'clamp' });
Slide In
const translateX = interpolate(frame, [0, 30], [-100, 0], { extrapolateRight: 'clamp' });
Spring Physics
const scale = spring({ frame, fps, config: { damping: 10, stiffness: 100 } });
Sequences (Staggered Timing)
<Sequence from={0} durationInFrames={60}>
<Title text="Part 1" />
</Sequence>
<Sequence from={60} durationInFrames={60}>
<Title text="Part 2" />
</Sequence>
Data-Driven Video
// Pass data as props to composition
const data = [
{ label: 'Jan', value: 42 },
{ label: 'Feb', value: 78 },
{ label: 'Mar', value: 95 },
];
// Animate bar chart based on frame
const progress = interpolate(frame, [0, 60], [0, 1], { extrapolateRight: 'clamp' });
Prerequisites Check
Before scaffolding or rendering, verify:
# Node.js required (v18+) node --version # Chrome/Chromium required for rendering if command -v google-chrome >/dev/null 2>&1; then echo "Chrome found" elif command -v chromium >/dev/null 2>&1; then echo "Chromium found" elif [ -d "/Applications/Google Chrome.app" ]; then echo "Chrome found (macOS)" else echo "WARNING: Chrome/Chromium not found - rendering may fail" echo "Install: brew install --cask google-chrome (macOS)" fi
Error Handling
| Error | Action |
|---|---|
| Node.js not installed | Tell user to install Node.js 18+ |
| Chrome not found | Suggest brew install --cask google-chrome (macOS) or apt install chromium (Linux) |
npx create-video fails | Try npm create video@latest or check npm registry |
| Render fails with memory error | Reduce resolution or use --concurrency 1 |
| TypeScript errors | Check composition imports and prop types |
