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

How to use

Read individual rule files for detailed explanations and code examples:

Core Animation & Timing

• references/animations.md - Fundamental animation techniques for Remotion
• references/timing.md - Interpolation curves: linear, easing, spring animations
• references/sequencing.md - Delay, trim, and limit duration of items
• references/trimming.md - Cut the beginning or end of animations

Compositions & Metadata

• references/compositions.md - Defining compositions, stills, folders, default props
• references/calculate-metadata.md - Dynamically set composition duration, dimensions, and props

Assets & Media

• references/assets.md - Importing images, videos, audio, and fonts
• references/images.md - Embedding images using the Img component
• references/videos.md - Embedding videos with trimming, volume, speed, looping, pitch
• references/audio.md - Using audio and sound with trimming, volume, speed, pitch
• references/gifs.md - Displaying GIFs synchronized with timeline

Text & Typography

• references/text-animations.md - Typography and text animation patterns
• references/measuring-text.md - Measuring text dimensions, fitting text, checking overflow
• references/fonts.md - Loading Google Fonts and local fonts

Captions & Transcription

• references/display-captions.md - Displaying captions with TikTok-style pages and word highlighting
• references/import-srt-captions.md - Importing .srt subtitle files using @remotion/captions
• references/transcribe-captions.md - Transcribing audio to generate captions

Data Visualization

• references/charts.md - Chart and data visualization patterns

Advanced Features

• references/3d.md - 3D content using Three.js and React Three Fiber
• references/lottie.md - Embedding Lottie animations
• references/transitions.md - Scene transition patterns

Styling & Layout

• references/tailwind.md - Using TailwindCSS in Remotion
• references/measuring-dom-nodes.md - Measuring DOM element dimensions

Media Processing (Mediabunny)

• references/can-decode.md - Check if a video can be decoded by the browser
• references/extract-frames.md - Extract frames from videos at specific timestamps
• references/get-audio-duration.md - Getting the duration of an audio file
• references/get-video-dimensions.md - Getting the width and height of a video file
• references/get-video-duration.md - Getting the duration of a video file

Quick Start Example

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
