🎬 Viral Script Agent

🎬 Viral Video Script & Production Automation (Built with N8N + AI)

---

Welcome to the official documentation for the "Viral Video Automation Workflow" — a 3-phase beast that turns your raw videos into polished scripts, PDFs, and production notes using N8N + GPT + Gemini + a bit of automation magic. 🪄

This Notion page breaks it down block-by-block so even your AI-curious cousin can follow along. 👨‍👩‍👧‍👦

---

🚀 Overview: What Does This Workflow Do?

This automation helps you:

• 🔍 Analyze a video using AI
• ✍️ Generate a viral-ready script
• 🎞 Create production notes
• 📄 Export beautiful PDF documents
• 🔁 All of this happens on autopilot once a form is submitted!

---

🧱 PHASE 1: Analyze Video Content (Gemini Magic)

🎯 Goal: Extract valuable insights from the submitted video

🔗 Trigger:

• 📝 A form submission triggers the entire workflow (e.g., Tally or Typeform → Webhook)

🛠 Steps:

1. Get Video - HTTP Node 📥
   Pulls the video file or URL submitted from the form.

   https://generativelanguage.googleapis.com/upload/v1beta/files?key= YOUR API KEY
   
   X-Goog-Upload-Command
   start, upload, finalize
   
   X-Goog-Upload-Header-Content-Length
   {{ $json["Viral Video Input"].size }}
   
   X-Goog-Upload-Header-Content-Type
   video/mp4
   
   Content-Type
   video/mp4
   
   Send Body
   Body Content Type
   n8n Binary File - Input Data Field Name
   Yourname
   

Headers & Body setup as per n8n Binary Input.

2. Wait Node ⏳

   • Gives time for the video to render (buffering logic).

3. Get Video Analysis - HTTP Node 🔎 Sends the video to Gemini for transcription or scene breakdown.

        }
      ]
    }
   ]
   }
   
   

4. Gemini Analysis (AI Magic) ✨

   • Breaks down transcript into topics, tone, hooks, storytelling angles.

🎤 PHASE 2: Create VIRAL YouTube/Instagram Script (GPT-4o Style)

🎯 Goal: Turn AI insights into a viral-ready script formatted beautifully.

💡 Components:

• 🤖 AI Agent (Claude 4 Sonnet via OpenRouter)

  • Input: Video analysis + Prompt
  • Output: 3 viral script variations

  USER PROMPT
  
    Create 3 distinct Instagram Reel script variations based on this analysis. Provide all 3 scripts in your response without asking for confirmation.
  
  ANALYSIS:
  
  **ANALYSIS RESULTS:**
  {{ $json.candidates[0].content.parts[0].text }}
  
  **USER REQUIREMENTS:**
  
  - Topic: {{ $('On form submission').item.json['What\'s your topic '] }}
  - Format:{{ $('On form submission').item.json['Target Format '] }}
  - Brand Voice: {{ $('On form submission').item.json['Brand Voice '] }}
  - Target Audience: {{ $('On form submission').item.json['Your target audience '] }}
  
  **KEY SUCCESSFUL ELEMENTS TO REPLICATE:**
  ✓ Strong curiosity hook ("Mujhe Samaj Nahi Aa Raha")
  ✓ AI/No-code trending topic
  ✓ Clear value proposition (create apps without coding)
  ✓ Fast-paced, visually engaging format
  ✓ Simple, direct CTA ("Comment Magic")
  ✓ Educational content with immediate value
  
  **CREATE 3 SCRIPT VARIATIONS (30-60 seconds each):**
  
  For each script, provide:
  
  **SCRIPT [1/2/3]: [Creative Title]**
  
  **Hook (0-3 seconds):**
  [Attention-grabbing opening that stops scrolling]
  
  **Problem Setup (3-15 seconds):**
  [Establish pain point/challenge]
  
  **Solution Reveal (15-45 seconds):**
  [Show the tool/process with clear value demonstration]
  
  **Benefits/Social Proof (45-55 seconds):**
  [Quick benefits that make viewers want to save]
  
  **Call-to-Action (55-60 seconds):**
  [Specific engagement request]
  
  **Text Overlays:**
  [List 8-10 key text overlays for silent viewing]
  
  **Visual Direction:**
  [Camera angles, demonstrations, props needed]
  
  **Hashtag Strategy:**
  [15-20 hashtags: 5 high-competition, 10 medium, 5 low-competition]
  
  **Hook Variation:**
  [What makes this hook different from the others]
  
  **Target Audience Angle:**
  [Which segment of your audience this will resonate with most]
  
  **Viral Prediction Score:** [X/10 with reasoning]
  
  ---
  
  **REQUIREMENTS:**
  
  - Each script must be DISTINCT with different hooks and angles
  - Optimize for Instagram algorithm (high watch time, saves, comments)
  - Include trending elements while staying authentic
  - Focus on mobile viewing experience
  - Make it save-worthy with actionable value
  - Ensure silent viewing compatibility
  
  **TRENDING ELEMENTS TO CONSIDER:**
  
  - AI tools are massively trending
  - No-code/automation content performs well
  - Before/after demonstrations get high engagement
  - "Secret" or "hidden" tool reveals drive curiosity
  - Educational content with immediate value gets saved
  
  Create scripts that feel authentic to the brand voice while maximizing viral potential!
  
  IMPORTANT: Provide all 3 complete script variations in your response. Do not ask for confirmation or mention that you're creating scripts. Start directly with SCRIPT 1.
  

  SYSTEM PROMPT
  
  You are an expert Instagram script writer and viral content strategist. You specialize in creating high-engagement Reels that stop the scroll, provide value, and drive massive engagement. You understand Instagram's algorithm, trending formats, and what makes content shareable and save-worthy.
  

• 🧹 Cleanup - Code Node

• Removes AI fluff (e.g., “Would you like me to continue...”)

  // Clean Claude output - Remove unwanted intro/outro text
  const claudeOutput = $input.first().json.output;

  // Remove common unwanted phrases
  let cleanedOutput = claudeOutput
    .replace(/I'll create \d+ distinct.*?[\n\r]/g, '')
    .replace(/Would you like me to continue.*?$/g, '')
    .replace(/\[Continued in next part.*?\]/g, '')
    .replace(/^.*?focusing on.*?[\n\r]/g, '')
    .trim();

  // Ensure it starts with SCRIPT 1
  if (!cleanedOutput.startsWith('**SCRIPT 1')) {
    const scriptStart = cleanedOutput.indexOf('**SCRIPT 1');
    if (scriptStart > 0) {
      cleanedOutput = cleanedOutput.substring(scriptStart);
    }
  }

  return [{
    ...($input.first().json),
    output: cleanedOutput,
    cleaned: true
  }];

• 📝 Markdown → HTML - Code Node

• Converts script to structured HTML

  const md = $json.output;

  if (!md) {
    throw new Error('Output field is empty or missing');
  }

  let html = md
    .replace(/^## (.*$)/gim, '<h2>$1</h2>')  // h2 first
    .replace(/^# (.*$)/gim, '<h1>$1</h1>')   // then h1
    .replace(/\*\*(.*)\*\*/gim, '<b>$1</b>') // bold
    .replace(/\*(.*)\*/gim, '<i>$1</i>')     // italic
    .replace(/\n/gim, '<br>');                // line breaks

  return [{ html }];

• Complete HTML Document Structure - Code Node Adds proper document headers, tags, and layout.

    const rawHtml = $json.html;  // your current HTML output

    const fullHtml = `
    <!DOCTYPE html>
    <html>
    <head>
      <meta charset="UTF-8">
      <title>Converted PDF</title>
    </head>
    <body>
      ${rawHtml}
    </body>
    </html>
    `;

    return [{ html: fullHtml }];

• 🎨 CSS Styling - Code Node

• Adds beautiful fonts, colors, layout, and highlights

  const rawHtml = $json.html;
<html>
const fullHtml = `
<head>
  <meta charset="UTF-8" />
<!DOCTYPE html>
