🚀 Overview
🚀 Overview This n8n automation workflow streamlines the creation of professional video ad scripts tailored for Veo 3 by turning basic user inputs into cinematic, consistent, and highly structured prompts. Whether you're a marketing agency, content creator, or small business, this workflow ensures high-quality AI video generation at scale—without needing a professional copywriter or creative director. 🛠️ How It Works 📝 Form Trigger Captures initial inputs via a web form: Ad Category: Dropdown (Before & After, Brand Awareness, UGC Style, Educational) Environment: Text (short description of setting/location) Script: Raw ad copy Spokesperson: Basic character idea (e.g., “young woman, confident, skincare expert”) 🧠 Build Persona Node Uses GPT-4o-Mini to expand spokesperson input into a full character description. Output includes: Age Race Clothing Hairstyle Tone/Demeanor Ensures visual consistency in AI-generated video scenes. 🌆 Build Environment Node Transforms environment text into a detailed, cinematic setting. Adds descriptive elements like: Lighting style Architecture or background Atmosphere (e.g., soft morning glow, modern interiors) ✂️ Generate Copy Node Breaks the full script into 10-second readable segments for smooth pacing. Helps tools like Veo 3 maintain flow, coherence, and readability. Outputs concise, camera-ready lines for each section. 📄 Google Docs Integration Auto-updates a ready-to-use script template in Google Docs. Replaces placeholders with content from the 3 AI nodes: Cinematic shot: (Build Persona) in (Build Environment). They confidently address the camera: (Generate Copy). Professional lighting emphasizes credibility throughout. Final result: a polished video ad prompt, ready for Veo 3 or any AI video tool. 💸 Cost Efficiency Advantage Using the Veo 3 API directly costs $0.50 per second — meaning a simple 5-second video costs $3.75, and a 6-clip project could run up to $24. However, this workflow is optimized for Veo 3's Fast on Flow mode, which costs just $0.20 per clip. 🔍 Real Example: 6 clips = $1.20 Savings = Over 90% More room for testing, iteration, and scaling This isn’t just smart automation — it’s financially strategic. 🔧 Setup Instructions ✅ Prerequisites Active n8n instance (Cloud or Self-Hosted) OpenAI API Key (for GPT-4) Google Docs API credentials ⚙️ Configuration Steps Import the workflow into your n8n instance Add OpenAI credentials to the AI nodes Set up Google Docs integration in n8n Copy this template: 👉 Veo 3 Script Template Update the Google Docs node with your copy’s URL Test the flow by submitting the form 💼 Use Cases Marketing Agencies: Quickly generate ad scripts for multiple campaigns Content Creators: Scale up content production without creative burnout AI Video Producers: Maintain detailed, consistent inputs for each render Small Business Owners: Create pro-grade ads without outsourcing 🎯 Benefits ✨ Consistency: AI ensures visual + narrative alignment ⚡ Speed: Go from rough idea to finished ad script in seconds 📈 Scalability: Handle multiple clients and campaigns simultaneously 🎥 Quality Output: Templates and pacing are optimized for real-world video use 💰 Cost Savings: Save up to 90% vs API-only generation..
