📄 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.
