💥 Automate video ads with NanoBanana, Seedream 4, ChatGPT Image and Veo 3

Who is this for?

This template is designed for marketers, content creators, and e-commerce brands who want to automate the creation of professional ad videos at scale. It’s ideal for teams looking to generate consistent, high-quality video ads for social media without spending hours on manual design, editing, or publishing.

What problem is this workflow solving? / Use case

Creating video ads usually requires multiple tools and a lot of time: writing scripts, designing product visuals, editing videos, and publishing them across platforms.
This workflow automates the entire pipeline — from idea to ready-to-publish ad video — ensuring brands can quickly test campaigns and boost engagement without production delays.

What this workflow does

  1. Generates ad ideas from Telegram input (text + product image).
  2. Creates product visuals using multiple AI image engines:
    • 🌊 Seedream 4.0 (realistic visuals)
    • 🍌 NanoBanana (image editing & enhancement)
    • 🤖 ChatGPT Image / GPT-4o (creative variations)
  3. Produces cinematic video ads with Veo 3 based on AI-generated scripts.
  4. Merges multiple short clips into a polished final ad.
  5. Publishes automatically to multiple platforms (TikTok, Instagram, LinkedIn, X, Threads, Facebook, Pinterest, Bluesky, YouTube) via Blotato.
  6. Stores metadata and results in Google Sheets & Google Drive for easy tracking.
  7. Notifies you via Telegram with the video link and copy.

Setup

  1. Connect your accounts in n8n:
    • Telegram API (for input and notifications)
    • Google Drive + Google Sheets (storage & tracking)
    • Kie AI API (Seedream + Veo 3)
    • Fal.ai API (NanoBanana + video merging)
    • OpenAI (for script and prompt generation)
    • Blotato API (for social publishing)
  2. Prepare a Google Sheet with brand info and settings (product name, category, features, offer, website URL).
  3. Deploy the workflow and connect your Telegram bot to start sending ad ideas (photo + caption).
  4. Run the workflow — it will automatically generate images, create videos, and publish to your chosen channels.

How to customize this workflow to your needs

  • Brand customization: Adjust the Google Sheet values to reflect your brand’s offers and product features.
  • Platforms: Enable/disable specific Blotato nodes depending on which platforms you want to publish to.
  • Video style: Edit the AI agent’s system prompt to control tone, format, and transitions (cinematic, playful, modern, etc.).
  • Notifications: Adapt Telegram nodes to send updates to different team members or channels.
  • Storage: Change the Google Drive folder IDs to store generated videos and images in your preferred location.

This workflow lets you go from idea → images → cinematic ad video → auto-published content in minutes, fully automated.

Automate Video Ad Campaign Creation with AI (NanoBanana, Seedream, GPT-4o, Veo-3)

This n8n workflow automates the process of generating and publishing video ad campaigns by leveraging AI models (GPT-4o, Veo-3) and integrating with NanoBanana and Seedream platforms. It streamlines the entire campaign creation process, from initial data input to final ad generation and notification.

What it does

This workflow simplifies the creation of video ad campaigns through the following steps:

  1. Triggers on Telegram Message: The workflow starts when a specific command or message is received via Telegram.
  2. Initial Data Setup: It sets up initial data, likely including campaign parameters or prompts for the AI.
  3. Fetches Campaign Data: It retrieves campaign-related information from a Google Sheet, such as product details, target audience, or ad copy.
  4. Generates Ad Concepts with AI: An AI Agent (powered by LangChain, likely using GPT-4o) processes the input data to generate creative ad concepts and scripts.
  5. Parses AI Output: The AI's structured output (e.g., JSON) is parsed to extract key elements for the ad campaign.
  6. Creates Video Ad with NanoBanana/Seedream: It makes an HTTP request to a video generation platform (implied to be NanoBanana/Seedream) to create the video ad using the AI-generated concepts.
  7. Waits for Video Processing: The workflow pauses to allow time for the video generation platform to process and render the video.
  8. Retrieves Video Ad Details: After the wait, it fetches the details or URL of the newly created video ad from Google Drive.
  9. Updates Google Sheet: The workflow updates the Google Sheet with the generated video ad details, ensuring all campaign information is centralized.
  10. Notifies via Telegram: Finally, it sends a notification via Telegram with the details of the newly created video ad campaign.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance.
  • Telegram Account & Bot: A Telegram bot and chat ID configured for triggering and notifications.
  • Google Sheets Account: Access to a Google Sheet containing campaign data.
  • Google Drive Account: For storing and retrieving generated video ads.
  • OpenAI API Key: For the AI Agent (GPT-4o) to generate ad concepts.
  • NanoBanana/Seedream Account: Access to the video generation platform (via HTTP Request node). This likely requires API keys or authentication for their services.

Setup/Usage

  1. Import the workflow: Download the JSON file and import it into your n8n instance.
  2. Configure Credentials:
    • Set up your Telegram Bot API Token credential for both the "Telegram Trigger" and "Telegram" nodes.
    • Configure your Google OAuth 2.0 credential for "Google Sheets" and "Google Drive" nodes.
    • Set up your OpenAI API Key credential for the "OpenAI Chat Model" and "OpenAI" nodes.
    • Configure any necessary HTTP Request credentials for the NanoBanana/Seedream API calls (e.g., API Key in headers or query parameters).
  3. Update Node Parameters:
    • Telegram Trigger: Specify the command or message that should trigger the workflow.
    • Google Sheets: Update the Spreadsheet ID and sheet names to match your campaign data.
    • HTTP Request: Adjust the URL, headers, and body of the HTTP request to interact correctly with the NanoBanana/Seedream API, passing the AI-generated ad concepts.
    • Google Drive: Specify the folder where generated videos should be stored or retrieved from.
    • AI Agent / OpenAI Nodes: Review and adjust the prompts or model parameters as needed for optimal ad concept generation.
    • Wait Node: Adjust the wait time if video processing takes longer or shorter.
  4. Activate the workflow: Once configured, activate the workflow to start automating your video ad campaigns.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
