# Remotion - Video Creation in React

Comprehensive skill set for creating programmatic videos using Remotion, a framework for creating videos programmatically using React.

## When to use

Use this skill whenever you are dealing with Remotion code to obtain domain-specific knowledge about:

- Creating video compositions with React components
- Animating elements using frame-based animations
- Working with audio, video, and image assets
- Building charts and data visualizations
- Implementing text animations and captions
- Using 3D content with Three.js
- Applying transitions and sequencing
- Integrating Tailwind CSS and Lottie animations

## Core Concepts

Remotion allows you to create videos using:
- **React Components**: Build video content with familiar React syntax
- **Frame-based Animations**: All animations driven by `useCurrentFrame()` hook
- **Compositions**: Define video compositions with duration, dimensions, and props
- **Assets**: Import and manipulate images, videos, audio, and fonts
- **Rendering**: Export videos programmatically with customizable settings

## Key Features

- Frame-by-frame control over animations
- Dynamic metadata calculation
- Media processing (trimming, volume, speed, pitch)
- Caption generation and display
- Data visualization with charts
- 3D content integration
- Professional text animations
- Scene transitions and sequencing

- **[references/extract-frames.md](references/extract-frames.md)** - Extract frames from videos at specific timestamps
- **[references/get-audio-duration.md](references/get-audio-duration.md)** - Getting the duration of an audio file
- **[references/get-video-dimensions.md](references/get-video-dimensions.md)** - Getting the width and height of a video file
- **[references/get-video-duration.md](references/get-video-duration.md)** - Getting the duration of a video file

## Quick Start Example

```tsx
import { useCurrentFrame, useVideoConfig, interpolate } from "remotion";

export const MyComposition = () => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  const opacity = interpolate(frame, [0, 2 * fps], [0, 1], {
    extrapolateRight: 'clamp',
  });

  return (
    <div style={{ opacity }}>
      <h1>Hello Remotion!</h1>
    </div>
  );
};
```

## Best Practices

1. **Always use `useCurrentFrame()`** - Drive all animations from the current frame
2. **Avoid CSS animations** - They won't render correctly in videos
3. **Think in seconds** - Multiply time in seconds by `fps` for frame calculations
4. **Use interpolate for smooth animations** - Built-in interpolation with easing functions
5. **Clamp extrapolation** - Prevent values from exceeding intended ranges
6. **Test frequently** - Preview in Remotion Studio before rendering
