Remotion Tutorial Generator

This skill enables you to create professional tutorial and introduction videos for software projects using Remotion, a React-based video generation framework.

Core Capabilities

1. Project Analysis: Examine codebase structure, workflows, and architecture
2. Video Planning: Design video chapters that align with project workflows
3. Remotion Setup: Initialize and configure Remotion projects
4. Component Generation: Create video compositions with scenes, transitions, and animations
5. Content Alignment: Ensure video content accurately reflects project functionality

Video Generation Workflow

Phase 1: Project Discovery

Before generating any video, thoroughly analyze the target project:

1. Read Project Documentation

   • README.md, CLAUDE.md, or similar documentation files
   • Identify key features, architecture, and user workflows
   • Note the tech stack and main dependencies

2. Analyze Code Structure

   • Examine directory structure and main entry points
   • Identify core components, services, and data flows
   • Map out user journeys and key interactions

3. Identify Demo-worthy Features

   • List features that should be highlighted in the video
   • Prioritize based on importance and visual appeal
   • Consider target audience (developers, users, stakeholders)

Phase 2: Video Structure Planning

Create a structured video outline with chapters:

1. Chapter Breakdown

   • Intro (5-10 seconds): Project name, tagline, branding
   • Overview (10-20 seconds): High-level purpose and value proposition
   • Key Features (30-60 seconds per feature): Demonstrate main capabilities
   • Architecture (20-40 seconds): Visual representation of system design
   • Getting Started (20-30 seconds): Quick setup guide
   • Call to Action (5-10 seconds): Links, contributing, contact info

2. Timing Calculations

   • Set FPS (typically 30 or 60)
   • Calculate durationInFrames for each scene
   • Plan transition timing between scenes
   • Total video should be 2-5 minutes for tutorials

3. Visual Planning

   • Determine aspect ratio (16:9 for standard, 1:1 for social, 9:16 for mobile)
   • Plan color scheme matching project branding
   • Design text hierarchy and annotation styles
   • Plan code snippet displays if needed

Phase 3: Remotion Project Setup

Initialize the Remotion project:

# Create new Remotion project
npx create-video@latest

# Or add to existing project
npm install remotion

Phase 4: Composition Implementation

Main Video Composition

// src/Video.tsx
import {Composition} from 'remotion';
import {Intro} from './scenes/Intro';
import {Overview} from './scenes/Overview';
import {FeatureDemo} from './scenes/FeatureDemo';
import {Architecture} from './scenes/Architecture';
import {Outro} from './scenes/Outro';

export const RemotionVideo: React.FC = () => {
  const fps = 30;

  return (
    <>
      {/* Intro Scene */}
      <Sequence durationInFrames={fps * 8}>
        <Intro />
      </Sequence>

      {/* Overview Scene */}
      <Sequence from={fps * 8} durationInFrames={fps * 15}>
        <Overview />
      </Sequence>

      {/* Feature Demos */}
      <Sequence from={fps * 23} durationInFrames={fps * 45}>
        <FeatureDemo />
      </Sequence>

      {/* Architecture Diagram */}
      <Sequence from={fps * 68} durationInFrames={fps * 30}>
        <Architecture />
      </Sequence>

      {/* Outro */}
      <Sequence from={fps * 98} durationInFrames={fps * 10}>
        <Outro />
      </Sequence>
    </>
  );
};

Scene Components

Each scene should follow this pattern:

// src/scenes/FeatureDemo.tsx
import {useCurrentFrame, useVideoConfig, interpolate, spring} from 'remotion';
import {ChapterTitle} from '../components/ChapterTitle';
import {Annotation} from '../components/Annotation';

export const FeatureDemo: React.FC = () => {
  const frame = useCurrentFrame();
  const {fps} = useVideoConfig();

  // Fade in title
  const titleOpacity = interpolate(frame, [0, 30], [0, 1], {
    extrapolateRight: 'clamp'
  });

  // Animate annotation entrance
  const annotationY = spring({
    frame: frame - 60,
    fps,
    config: {
      damping: 100,
      stiffness: 200,
      mass: 0.5
    }
  });

  return (
    <div style={{
      width: '100%',
      height: '100%',
      backgroundColor: '#0f172a',
      position: 'relative'
    }}>
      {/* Chapter Title */}
      <ChapterTitle
        title="Key Features"
        subtitle="Real-time bidding and checkout"
        opacity={titleOpacity}
      />

      {/* Feature Demonstration */}
      <div style={{
        position: 'absolute',
        top: '30%',
        left: '10%',
        right: '10%'
      }}>
        {/* Screenshot or animation here */}
      </div>

      {/* Annotation */}
      {frame > 60 && (
        <Annotation
          text="Guests can place bids in real-time"
          position={{
            x: '20%',
            y: `${50 + annotationY * 10}%`
          }}
        />
      )}
    </div>
  );
};

Phase 5: Reusable Components

Chapter Title Component

// src/components/ChapterTitle.tsx
import React from 'react';

interface ChapterTitleProps {
  title: string;
  subtitle?: string;
  opacity?: number;
}

export const ChapterTitle: React.FC<ChapterTitleProps> = ({
  title,
  subtitle,
  opacity = 1
}) => {
  return (
    <div style={{
      position: 'absolute',
      top: '10%',
      left: '10%',
      right: '10%',
      opacity
    }}>
      <h1 style={{
        fontSize: '4rem',
        fontWeight: 'bold',
        color: '#ffffff',
        margin: 0,
        textShadow: '0 4px 8px rgba(0,0,0,0.3)'
      }}>
        {title}
      </h1>
      {subtitle && (
        <p style={{
          fontSize: '2rem',
          color: '#cbd5e1',
          marginTop: '1rem'
        }}>
          {subtitle}
        </p>
      )}
    </div>
  );
};

Transition Component

// src/components/Transition.tsx
import {useCurrentFrame, interpolate} from 'remotion';

interface TransitionProps {
  type: 'fade' | 'slide' | 'wipe';
  durationInFrames: number;
  direction?: 'in' | 'out';
  children: React.ReactNode;
}

export const Transition: React.FC<TransitionProps> = ({
  type,
  durationInFrames,
  direction = 'in',
  children
}) => {
  const frame = useCurrentFrame();

  const progress = interpolate(
    frame,
    [0, durationInFrames],
    direction === 'in' ? [0, 1] : [1, 0],
    {extrapolateLeft: 'clamp', extrapolateRight: 'clamp'}
  );

  const style: React.CSSProperties = (() => {
    switch (type) {
      case 'fade':
        return {opacity: progress};
      case 'slide':
        return {transform: `translateX(${(1 - progress) * -100}%)`};
      case 'wipe':
        return {clipPath: `inset(0 ${(1 - progress) * 100}% 0 0)`};
      default:
        return {};
    }
  })();

  return <div style={style}>{children}</div>;
};

Annotation Component

// src/components/Annotation.tsx
interface AnnotationProps {
  text: string;
  position: {x: string; y: string};
  arrow?: {from: string; to: string};
}

export const Annotation: React.FC<AnnotationProps> = ({
  text,
  position,
  arrow
}) => {
  return (
    <div style={{
      position: 'absolute',
      left: position.x,
      top: position.y,
      backgroundColor: '#fbbf24',
      color: '#1f2937',
      padding: '0.5rem 1rem',
      borderRadius: '0.5rem',
      fontSize: '1.5rem',
      fontWeight: '600',
      boxShadow: '0 4px 12px rgba(0,0,0,0.2)',
      zIndex: 100
    }}>
      {text}
      {arrow && (
        <svg
          style={{
            position: 'absolute',
            width: '100%',
            height: '100%',
            pointerEvents: 'none'
          }}
        >
          {/* Arrow implementation */}
        </svg>
      )}
    </div>
  );
};

Phase 6: Animation Patterns

Common Animation Helpers

// src/utils/animations.ts
import {interpolate, spring, SpringConfig} from 'remotion';

export const fadeIn = (frame: number, startFrame: number, duration: number) => {
  return interpolate(
    frame,
    [startFrame, startFrame + duration],
    [0, 1],
    {extrapolateRight: 'clamp', extrapolateLeft: 'clamp'}
  );
};

export const slideIn = (
  frame: number,
  fps: number,
  delay: number = 0,
  config?: SpringConfig
) => {
  return spring({
    frame: frame - delay,
    fps,
    config: config || {damping: 100, stiffness: 200, mass: 0.5}
  });
};

export const staggeredAppearance = (
  frame: number,
  itemIndex: number,
  staggerDelay: number
) => {
  const startFrame = itemIndex * staggerDelay;
  return interpolate(
    frame,
    [startFrame, startFrame + 20],
    [0, 1],
    {extrapolateRight: 'clamp', extrapolateLeft: 'clamp'}
  );
};

Phase 7: Audio Integration

Add background music and narration:

import {Audio, useCurrentFrame} from 'remotion';

// In your main composition
<Audio src="/audio/background-music.mp3" volume={0.3} />

// For narration synced to scenes
<Sequence from={fps * 8}>
  <Audio src="/audio/narration-overview.mp3" />
</Sequence>

Phase 8: Rendering

Render the video with appropriate settings:

# Preview in browser
npm run dev

# Render single frame for testing
npx remotion still src/index.ts MyVideo --frame=150 --output=preview.png

# Render full video
npx remotion render src/index.ts MyVideo output.mp4

# Render with custom settings
npx remotion render src/index.ts MyVideo output.mp4 \
  --codec=h264 \
  --scale=1 \
  --quality=90

Best Practices

Content Alignment

• Match Project Workflows: Video flow should mirror actual user journeys
• Accurate Representation: Show real features, not mockups
• Technical Accuracy: Verify architecture diagrams match implementation
• Update Regularly: Regenerate videos when major features change

Visual Design

• Consistent Branding: Use project colors, fonts, and logo
• Readable Text: Minimum 2rem font size, high contrast
• Smooth Animations: Prefer spring() for natural motion
• Visual Hierarchy: Most important info should be largest and centered

Performance

• Optimize Assets: Compress images and audio before importing
• Lazy Loading: Use dynamic imports for heavy components
• Frame Rate: 30fps is sufficient for most tutorials
• Resolution: 1080p (1920x1080) is standard for tutorials

Transitions

• Purposeful: Use transitions to signal topic changes
• Consistent Duration: Typically 0.5-1 second (15-30 frames at 30fps)
• Not Overdone: Too many fancy transitions are distracting
• Type Variety: Mix fade, slide, and wipe based on content flow

Annotations

• Timely: Appear when relevant feature is shown
• Concise: 5-10 words maximum
• Positioned Well: Don't obscure important content
• Animated Entrance: Use spring animations for natural feel

Example Implementation Checklist

When generating a tutorial video, complete these steps:

• Analyze project structure and identify main workflows
• Read project documentation (README, CLAUDE.md)
• Create video outline with chapter breakdown
• Calculate timing for all scenes (in frames)
• Initialize Remotion project structure
• Create reusable component library (ChapterTitle, Annotation, etc.)
• Implement Intro scene with project branding
• Implement Overview scene with value proposition
• Create Feature Demo scenes for each key feature
• Design Architecture visualization scene
• Create Getting Started / Call to Action scene
• Add transitions between all scenes
• Implement annotations highlighting key points
• Add background music and narration (if available)
• Test render individual scenes
• Render full video and review
• Adjust timing, animations, and content based on review
• Export final video with optimized settings

Common Patterns

Pattern 1: Multi-Feature Showcase

For projects with multiple features, create a carousel effect:

const features = [
  {title: 'Feature 1', description: '...', screenshot: '...'},
  {title: 'Feature 2', description: '...', screenshot: '...'},
  // ...
];

features.map((feature, index) => (
  <Sequence
    key={index}
    from={fps * (23 + index * 15)}
    durationInFrames={fps * 15}
  >
    <FeatureSlide feature={feature} />
  </Sequence>
));

Pattern 2: Code Walkthrough

Show code snippets with syntax highlighting:

import {CodeSnippet} from './components/CodeSnippet';

<Sequence from={fps * 50} durationInFrames={fps * 20}>
  <CodeSnippet
    language="typescript"
    code={`
      const handleBid = async (itemId: string, amount: number) => {
        await db.collection('bids').add({
          itemId,
          amount,
          timestamp: serverTimestamp()
        });
      };
    `}
    highlights={[2, 3, 4]} // Highlight specific lines
  />
</Sequence>

Pattern 3: Architecture Diagram

Animate system architecture components:

<Sequence durationInFrames={fps * 30}>
  <ArchitectureDiagram>
    <Box label="React Frontend" delay={0} />
    <Arrow from="frontend" to="firebase" delay={30} />
    <Box label="Firebase" delay={30} />
    <Arrow from="firebase" to="firestore" delay={60} />
    <Box label="Firestore DB" delay={60} />
  </ArchitectureDiagram>
</Sequence>

Troubleshooting

• Video too long: Reduce durationInFrames or remove less important scenes
• Animations jerky: Use spring() instead of interpolate() for smoother motion
• Text unreadable: Increase font size and improve contrast
• Render takes too long: Reduce resolution or frame rate for testing
• Out of sync audio: Ensure all Sequence timings are accurate
