Why Automate Video Ad Creation?

  • Save hours of manual editing with fully automated workflows
  • Easily scale ad production for clients or SaaS platforms
  • Maintain data privacy with self-hosted solutions
  • Integrate cutting-edge AI tools for next-level ad quality

Step 1: Setting Up Your Self-Hosted n8n Instance

Why Self-Hosting Matters

Self-hosting on a cloud platform or VPS gives you:

  • Complete control and privacy over your data
  • Flexible server specs for performance and scalability
  • The ability to run advanced, resource-intensive workflows

Quick Setup Guide

  1. Choose a cloud hosting provider and select a virtual private server (VPS)
  2. Pick a plan with at least 2 vCPU, 8GB RAM, and sufficient disk space and bandwidth
  3. Enable daily auto-backups for workflow safety
  4. Select your preferred server location for optimal latency
  5. Install the n8n application image for quick deployment

Pro Tip: Self-hosting ensures your workflow is secure and easily scalable as your needs grow.

Step 2: Downloading & Importing the Free Video Ad Generator Template

A pre-built n8n workflow template can help you get started quickly:

  • Download a template JSON file from community or open-source repositories
  • Import it into your n8n instance using the "Import from File" feature
  • Hook up your own API credentials (Telegram, Google, OpenRouter, Veo3)

This jumpstarts your setup, allowing immediate hands-on experimentation with minimal configuration.

Step 3: Workflow Architecture—How the AI Video Ad Generator Works

High-Level Workflow Breakdown

  1. User triggers workflow via Telegram (uploads a product image)
  2. Image analysis: AI identifies product, brand, and key features
  3. Prompt generation: AI crafts prompts for both image and video creation
  4. Image creation: NanoBanana generates a custom product image
  5. Image upload: Image is saved to Google Drive, link updated in Google Sheet
  6. Video creation: Veo3 (via Foul or KIE API) animates a short ad video using the generated prompt and image
  7. Video upload: Video is saved and linked
  8. Telegram notification: User receives links to final assets

Visual Workflow Example

  • Telegram → Image Analysis → Prompt Generation → Image Creation → Video Creation → Delivery

"This workflow lets you go from a single prompt to a finished, professional video ad in just a few automated steps."

Step 4: Connecting and Configuring APIs (Telegram, Google, OpenRouter, Veo3)

Telegram Bot Setup

  • Register a new bot via BotFather in Telegram
  • Obtain your unique access token
  • Add credentials to n8n's Telegram Trigger node

Google Sheets & Drive Integration

  • Set up OAuth credentials in Google Cloud Console
  • Authorize n8n to access your Google Sheets & Drive
  • Use Google Sheets to track project status and store asset links

OpenRouter & NanoBanana (Image Generation)

  • Register for an API key at OpenRouter.ai
  • Use the "NanoBanana" model for fast, high-quality image outputs
  • Send prompts (generated by the AI agent) with product details and branding

Veo3 via Foul or KIE API (Video Generation)

  • Sign up for Foul or KIE API and generate your API key
  • Specify prompt, image URL, and aspect ratio (9:16 for short form, 16:9 for long form)
  • Wait for video processing (usually ~2 minutes)
  • Retrieve video file via API and upload to Google Drive

"Bringing all these APIs together in n8n is what makes the workflow fully automated and scalable."

Step 5: Detailed Node-by-Node Workflow Walkthrough

Telegram Trigger: Starting the Workflow

  • User uploads image via Telegram
  • n8n fetches the image file and relevant metadata

Image Analysis & Data Extraction

  • AI analyzes the image for product, color, brand, and character details
  • Data is parsed from JSON and stored with a unique timestamp identifier

Data Logging with Google Sheets

  • Append a new row for each ad creation task
  • Store index, product info, image, video links, status (e.g., "image done", "video done")

AI Agent for Prompt Engineering

  • Generates structured prompts for both image and video creation
  • Customizable system messages for different creative directions

Image Creation with NanoBanana

  • Sends prompt to NanoBanana via OpenRouter
  • Handles base64 image encoding, saves as PNG
  • Uploads to Google Drive, updates Sheet with public link

Video Creation with Veo3

  • Sends prompt, image URL to Veo3 via Foul/KIE API
  • Handles aspect ratio and other video settings
  • Waits for processing, retrieves video URL
  • Uploads video to Drive, updates Sheet

User Notification

  • Telegram bot sends back clickable links to the final image and video ad

Actionable Tip: Always test each node independently before running the full workflow to debug issues quickly.

Best Practices & Tips for Scaling Your AI Video Ad Generator

Optimizing for Agencies and SaaS

  • Use scalable server plans to handle multiple ad requests simultaneously
  • Automate daily backups to prevent data loss
  • Customize prompts for each client or campaign for unique branding
  • Monitor API usage and costs (image/video generation is typically $0.50 per ad)

Troubleshooting Common Issues

  • Ensure all API keys are current and correctly entered
  • Double-check OAuth configurations for Google integrations
  • Use structured prompts to maintain consistent AI output quality
