📄 What this workflow does

This workflow turns your n8n into an automated product-video generator powered by Google Sheets. When a new row is added with status = run, it:

  • Downloads the product image from Google Drive.
  • Converts the image to base64 and sends it to Gemini, which creates a branded ad-style variant.
  • Saves the generated image back into a designated Google Drive folder.
  • Sends the image to FAL (image-to-video) to generate a short promotional video clip.
  • Polls FAL’s response_url until the video is ready.
  • Uploads the video to Google Drive (videos folder).
  • Updates the original Google Sheet row with the video link and sets status = finished.
  • Handles API latency via wait/polling and logs failures into the sheet if needed.

👤 Who is this for

  • Marketing teams automating creative asset production.
  • E-commerce businesses needing quick product promo videos.
  • Agencies creating branded ad content at scale.

✅ Requirements

  • An n8n instance.
  • A Google Sheet with at least these columns: STT, link_image, note, status, link_video.
  • Google Sheets & Google Drive OAuth2 credentials connected in n8n.
  • Gemini API key (for ad-style image generation).
  • FAL API key (for image-to-video).

⚙️ How to set up

  1. Import the provided workflow JSON into n8n.
  2. Connect Google Sheets credentials and point to your sheet (documentId + gid).
  3. Connect Google Drive credentials and update folder IDs in the two Upload File nodes (images/videos).
  4. Add Gemini and FAL API keys in the respective HTTP Request headers (via Credentials).
  5. Test: add a row with link_image, note, and status = run. The workflow should generate and save a video, then update the sheet with the link.

🔁 How it works

  • Trigger → Google Sheets Trigger fires on rowAdded where status = run.
  • Pre-processing → Download the product image from Google Drive → extract base64.
  • LLM Image Generation → Gemini generates an ad-style variant based on note.
  • Storage → Upload the generated image into the “images” Drive folder.
  • Video Creation → FAL converts the branded image into a short video.
  • Polling → Wait node + HTTP Request check job status until video is completed.
  • Write-back → Upload final video into the “videos” Drive folder, update the sheet with the link_video, and set status = finished.

Generate Product Videos Automatically with Gemini, FAL, and Google Workspace

This n8n workflow automates the creation of product videos by leveraging AI models (Gemini) for script generation, a video generation service (FAL), and Google Workspace for data management and file storage. It streamlines the process from a simple spreadsheet entry to a ready-to-use video.

What it does

This workflow simplifies and automates the following steps:

  1. Monitors Google Sheets: It triggers when a new row is added to a specified Google Sheet, acting as the input for new product video requests.
  2. Generates Video Script (Gemini): It sends product details from the Google Sheet to a Gemini AI model via an HTTP Request to generate a compelling video script.
  3. Generates Video (FAL): The generated script is then sent to the FAL video generation API (via another HTTP Request) to create the actual video.
  4. Uploads Video to Google Drive: The completed video file is uploaded to a designated folder in Google Drive.
  5. Updates Google Sheet: The Google Sheet is updated with the URL of the newly generated and uploaded video, indicating completion.
  6. Handles Delays: A Wait node is included to manage potential rate limits or processing times between API calls, ensuring smooth execution.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance to host and execute the workflow.
  • Google Account: A Google account with access to Google Sheets and Google Drive.
    • Google Sheets Credential: Configured in n8n to allow the workflow to read from and write to your spreadsheet.
    • Google Drive Credential: Configured in n8n to allow the workflow to upload files to your Drive.
  • Gemini API Access: Access to the Gemini API for script generation. This will require an API key or appropriate authentication for the HTTP Request node.
  • FAL API Access: Access to the FAL video generation API. This will require an API key or appropriate authentication for the HTTP Request node.
  • Google Sheet: A Google Sheet set up with columns for product information (e.g., product name, description) and a column to store the generated video URL.

Setup/Usage

  1. Import the workflow: Download the JSON content and import it into your n8n instance.
  2. Configure Credentials:
    • Set up your Google Sheets credential.
    • Set up your Google Drive credential.
    • Configure the HTTP Request nodes for Gemini and FAL with your respective API keys or authentication methods.
  3. Specify Google Sheet: In the "Google Sheets Trigger" node, select your Google Sheet and the sheet name that will serve as the input for new product video requests.
  4. Configure Gemini Request: In the "HTTP Request" node for Gemini, ensure the payload correctly sends product details from the Google Sheet to the Gemini API for script generation.
  5. Configure FAL Request: In the "HTTP Request" node for FAL, ensure the payload correctly sends the generated script to the FAL API for video creation.
  6. Specify Google Drive Folder: In the "Google Drive" node, select the folder where the generated videos should be uploaded.
  7. Map Data: Ensure all nodes are correctly configured to pass data between them (e.g., product details from Google Sheets to Gemini, script from Gemini to FAL, video URL from Google Drive back to Google Sheets).
  8. Activate the workflow: Once configured, activate the workflow. It will now automatically generate and upload product videos whenever a new row is added to your specified Google Sheet.

🎓 How to transform unstructured email data into structured format with AI agent

This workflow automates the process of extracting structured, usable information from unstructured email messages across multiple platforms. It connects directly to Gmail, Outlook, and IMAP accounts, retrieves incoming emails, and sends their content to an AI-powered parsing agent built on OpenAI GPT models. The AI agent analyzes each email, identifies relevant details, and returns a clean JSON structure containing key fields: From – sender’s email address To – recipient’s email address Subject – email subject line Summary – short AI-generated summary of the email body The extracted information is then automatically inserted into an n8n Data Table, creating a structured database of email metadata and summaries ready for indexing, reporting, or integration with other tools. --- Key Benefits ✅ Full Automation: Eliminates manual reading and data entry from incoming emails. ✅ Multi-Source Integration: Handles data from different email providers seamlessly. ✅ AI-Driven Accuracy: Uses advanced language models to interpret complex or unformatted content. ✅ Structured Storage: Creates a standardized, query-ready dataset from previously unstructured text. ✅ Time Efficiency: Processes emails in real time, improving productivity and response speed. *✅ Scalability: Easily extendable to handle additional sources or extract more data fields. --- How it works This workflow automates the transformation of unstructured email data into a structured, queryable format. It operates through a series of connected steps: Email Triggering: The workflow is initiated by one of three different email triggers (Gmail, Microsoft Outlook, or a generic IMAP account), which constantly monitor for new incoming emails. AI-Powered Parsing & Structuring: When a new email is detected, its raw, unstructured content is passed to a central "Parsing Agent." This agent uses a specified OpenAI language model to intelligently analyze the email text. Data Extraction & Standardization: Following a predefined system prompt, the AI agent extracts key information from the email, such as the sender, recipient, subject, and a generated summary. It then forces the output into a strict JSON structure using a "Structured Output Parser" node, ensuring data consistency. Data Storage: Finally, the clean, structured data (the from, to, subject, and summarize fields) is inserted as a new row into a specified n8n Data Table, creating a searchable and reportable database of email information. --- Set up steps To implement this workflow, follow these configuration steps: Prepare the Data Table: Create a new Data Table within n8n. Define the columns with the following names and string type: From, To, Subject, and Summary. Configure Email Credentials: Set up the credential connections for the email services you wish to use (Gmail OAuth2, Microsoft Outlook OAuth2, and/or IMAP). Ensure the accounts have the necessary permissions to read emails. Configure AI Model Credentials: Set up the OpenAI API credential with a valid API key. The workflow is configured to use the model, but this can be changed in the respective nodes if needed. Connect the Nodes: The workflow canvas is already correctly wired. Visually confirm that the email triggers are connected to the "Parsing Agent," which is connected to the "Insert row" (Data Table) node. Also, ensure the "OpenAI Chat Model" and "Structured Output Parser" are connected to the "Parsing Agent" as its AI model and output parser, respectively. Activate the Workflow: Save the workflow and toggle the "Active" switch to ON. The triggers will begin polling for new emails according to their schedule (e.g., every minute), and the automation will start processing incoming messages. --- Need help customizing?
