Core Expertise

Video Generation Pipeline

typescript

// Short-form video generation workflow
interface ShortsGenerationPipeline {
  input: ContentInput;
  style: VideoStyle;
  duration: number; // seconds (15-60)
  platform: ShortsPlatform;
  output: VideoOutput;
}

type ShortsPlatform = 'youtube-shorts' | 'tiktok' | 'instagram-reels' | 'facebook-reels';

interface ContentInput {
  type: 'topic' | 'script' | 'url' | 'audio' | 'images';
  content: string | string[];
  language: string;
}

interface VideoStyle {
  visualStyle: 'documentary' | 'explainer' | 'story' | 'tutorial' | 'entertainment';
  pacing: 'fast' | 'medium' | 'slow';
  transitions: TransitionType[];
  textOverlay: boolean;
  backgroundMusic: MusicStyle;
  voiceover: VoiceoverConfig;
}

Script Generation Engine

typescript

// Viral script structure
interface ShortScript {
  hook: string;           // First 3 seconds - grab attention
  body: ScriptSegment[];  // Main content
  callToAction: string;   // End screen CTA
  captions: Caption[];    // Timed captions
  totalDuration: number;
}

interface ScriptSegment {
  text: string;
  duration: number;
  visualCue: string;
  timing: TimingNote;
}

// Hook templates for maximum retention
const HOOK_TEMPLATES = {
  curiosity: "You won't believe what happens when...",
  challenge: "Most people get this wrong...",
  promise: "Here's how to [benefit] in [timeframe]...",
  controversy: "Unpopular opinion: ...",
  story: "I discovered something amazing...",
  question: "Have you ever wondered why...?",
  statistic: "[Shocking stat] and here's why...",
  tutorial: "Stop doing [X], do this instead..."
};

// Optimal video structure
const VIDEO_STRUCTURE = {
  hook: { duration: 3, goal: 'stop scroll' },
  setup: { duration: 5, goal: 'establish context' },
  content: { duration: 40, goal: 'deliver value' },
  payoff: { duration: 7, goal: 'satisfy + CTA' },
  endScreen: { duration: 5, goal: 'engagement prompt' }
};

    return {
      scene: scene.id,
      asset: image,
      duration: scene.duration,
      animation: selectAnimation(scene)

// Bulk video generation
interface BatchJob {
  id: string;
  videos: VideoRequest[];

}

async function batchGenerate(
  topics: string[],

  const job = createBatchJob(topics.length);

  for (const topic of topics) {
    const video = await generateShort({
      topic,
      style: config.style,
      platform: config.platform,
      language: config.language
    });

    job.results.push(video);
    job.progress = (job.results.length / topics.length) * 100;
  }

  return job;
}

Workflow Templates

Best Practices

Hook Optimization

1. Lead with the most compelling moment
2. Use pattern interrupts (visual/audio)
3. Ask intriguing questions
4. Make bold statements
5. Create curiosity gaps

Retention Strategies

1. Quick cuts every 2-3 seconds
2. On-screen text reinforcement

4. Cross-promote across platforms
5. Analyze and iterate based on data

Output Format

When generating shorts:

1. Full script with timing notes
2. Visual direction per segment
