# Shorts Generator — Code Examples

## Example 1

```typescript
// ShortGPT-style content engines
class ContentShortEngine {
  // For creating short-form content (15-60 seconds)
  async generate(params: {
    topic: string;
    style: VideoStyle;
    language: string;
    voiceProvider: 'elevenlabs' | 'edge-tts' | 'openai';
  }): Promise<ShortVideo> {
    const script = await this.generateScript(params.topic);
    const audio = await this.synthesizeVoiceover(script, params.voiceProvider);
    const visuals = await this.sourceVisuals(script);
    const captions = await this.generateCaptions(audio);

    return this.renderVideo({
      script,
      audio,
      visuals,
      captions,
      style: params.style
    });
  }
}

class ContentVideoEngine {
  // For longer content (1-10 minutes)
  async generate(params: {
    script: string;
    backgroundFootage: 'stock' | 'ai-generated' | 'custom';
    captionStyle: CaptionStyle;
    musicVolume: number;
  }): Promise<Video> {
    // Full video generation pipeline
  }
}

class ContentTranslationEngine {
  // For dubbing and translating existing videos
  async translate(params: {
    sourceVideo: string | File;
    targetLanguage: string;
    voiceCloning: boolean;
    keepOriginalMusic: boolean;
  }): Promise<TranslatedVideo> {
    const transcript = await this.transcribe(params.sourceVideo);
    const translation = await this.translate(transcript, params.targetLanguage);
    const newAudio = await this.synthesize(translation, params.voiceCloning);

    return this.replaceAudio(params.sourceVideo, newAudio);
  }
}
```

## Example 2

```typescript
// Animated caption styles
interface CaptionConfig {
  style: 'karaoke' | 'word-by-word' | 'sentence' | 'minimal';
  position: 'center' | 'bottom' | 'top';
  font: string;
  colors: {
    text: string;
    highlight: string;
    shadow: string;
  };
  animation: 'pop' | 'fade' | 'slide' | 'bounce';
  maxWords: number;
}

// Popular caption styles
const CAPTION_PRESETS = {
  tiktok: {
    style: 'word-by-word',
    font: 'Montserrat Bold',
    colors: { text: '#FFFFFF', highlight: '#FFD700', shadow: '#000000' },
    animation: 'pop',
    position: 'center'
  },
  hormozi: {
    style: 'karaoke',
    font: 'Impact',
    colors: { text: '#FFFFFF', highlight: '#FF0000', shadow: '#000000' },
    animation: 'pop',
    maxWords: 3
  },
  minimal: {
    style: 'sentence',
    font: 'Inter',
    colors: { text: '#FFFFFF', highlight: '#FFFFFF', shadow: '#00000080' },
    animation: 'fade'
  }
};

// Auto-sync captions with audio
async function generateSyncedCaptions(
  audio: AudioFile,
  style: CaptionConfig
): Promise<TimedCaption[]> {
  const transcript = await speechToText(audio);
  const wordTimings = await getWordTimings(audio, transcript);

  return formatCaptions(wordTimings, style);
}
```

## Example 3

```typescript
// Platform-specific requirements
const PLATFORM_SPECS = {
  'youtube-shorts': {
    maxDuration: 60,
    aspectRatio: '9:16',
    resolution: { width: 1080, height: 1920 },
    maxFileSize: '60MB',
    hashtags: 3,
    titleLimit: 100,
    features: ['end-screen', 'subscribe-prompt']
  },
  'tiktok': {
    maxDuration: 180, // 3 minutes
    aspectRatio: '9:16',
    resolution: { width: 1080, height: 1920 },
    maxFileSize: '287.6MB',
    hashtags: 5,
    features: ['duet', 'stitch', 'green-screen']
  },
  'instagram-reels': {
    maxDuration: 90,
    aspectRatio: '9:16',
    resolution: { width: 1080, height: 1920 },
    maxFileSize: '250MB',
    hashtags: 30,
    features: ['remix', 'templates', 'effects']
  }
};

// Platform-specific optimization
function optimizeForPlatform(
  video: RawVideo,
  platform: ShortsPlatform
): OptimizedVideo {
  const specs = PLATFORM_SPECS[platform];

  return {
    ...video,
    duration: Math.min(video.duration, specs.maxDuration),
    resolution: specs.resolution,
    metadata: generatePlatformMetadata(video, platform),
    endScreen: specs.features.includes('end-screen') ? generateEndScreen() : null
  };
}
