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 responseurl 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, linkimage, note, status, linkvideo. - 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 linkimage, 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 linkvideo, and set status = finished.
