Generate Product Videos Automatically with Gemini, FAL and Google Workspace

📄 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 Import the provided workflow JSON into n8n. Connect Google Sheets credentials and point to your sheet (documentId + gid). Connect Google Drive credentials and update folder IDs in the two Upload File nodes (images/videos). Add Gemini and FAL API keys in the respective HTTP Request headers (via Credentials). 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.
