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
