AI Product Video Generator with Background Removal

Overview

This workflow automates the creation of professional 3D product videos from a simple product photo submission. When a user submits a product photo and title through an n8n form, the workflow removes the background using remove.bg, generates a cinematic rotating product video using the Kling AI video API, and delivers the final result via email. All intermediate and final assets are organized in Google Drive and tracked in a Google Sheet for easy management.

This is particularly useful for e-commerce businesses, marketing teams, or product managers who need to quickly generate high-quality product videos without manual editing. The entire process runs automatically, saving hours of manual work per product.

Workflow Steps

1. On Form Submission (Form Trigger) — No auth. This node provides a web form where users can upload a product photo and enter a product title. The form is titled "Go 2 Market" and collects a file upload and text input.

2. Create Slug (Code Node) — No auth. This JavaScript code generates a URL-friendly slug from the product title by converting it to lowercase, replacing spaces with hyphens, and appending a random 6-character string for uniqueness. The slug is used as the folder name and identifier throughout the workflow.

3. Create folder (Google Drive) — OAuth2. Creates a new folder in Google Drive using the generated slug as the folder name. The folder is created in the root of "My Drive" and will contain all assets for this product.

4. Give Access to folder (Google Drive) — OAuth2. Makes the newly created folder publicly readable by setting the sharing permission to "anyone with the link" as a reader. This ensures the generated video URL can be accessed by the recipient.

5. Get Image File (Code Node) — No auth. Extracts the binary file data from the form submission. This node runs once and processes all uploaded files, preparing them for background removal.

6. Bg remove from image (HTTP Request) — API Key auth (X-API-Key header). Sends the uploaded image to remove.bg API to remove the background. Configured with size "auto" and expects the response as a file, which is stored in the output property "no-bg.png".

7. Upload original image (Google Drive) — OAuth2. Uploads the original product photo to the product's folder in Google Drive.

8. Upload original image in sheet (Google Sheets) — OAuth2. Appends a new row to the Google Sheet with the original image's web view link, the product title from the form, and the slug (folder name). This creates a record of the original submission.

9. Upload Remove BG image (Google Drive) — OAuth2. Uploads the background-removed image to the product's folder in Google Drive, with a filename prefixed by "(no-bg)".

10. Upload Remove BG image in sheet (Google Sheets) — OAuth2. Updates the Google Sheet row (matched by slug) with the background-removed image's web view link.

11. Extract Image ID from URL (Code Node) — No auth. Parses the Google Drive URL of the background-removed image to extract the file ID using a regular expression. This ID is needed for the video generation API.

12. Create video (HTTP Request) — API Key auth (Authorization header with "Key" prefix). Sends a request to the Kling AI video generation API (fal.ai) with a cinematic prompt describing a 360-degree rotating product shot. The image URL is constructed using the extracted file ID and Google Drive's direct download link format.

13. Wait (Wait Node) — No auth. Pauses execution for 40 seconds to allow the video generation process to complete. This is a polling delay before checking the status.

14. Check video status (HTTP Request) — API Key auth (Authorization header). Polls the status URL returned by the video creation API to check if the video is ready.

15. If (IF Node) — No auth. Checks if the video status equals "IN_PROGRESS". If true, it loops back to the Wait node for another 40-second delay. If false (completed), it proceeds to get the video link.

16. Get video link (HTTP Request) — API Key auth (Authorization header). Retrieves the final video URL from the response URL provided by the status check.

17. Convert video link to binary file (HTTP Request) — No auth. Downloads the video from the URL and converts it to a binary file, stored in the output property "Video-file".

18. Upload Video (Google Drive) — OAuth2. Uploads the generated video file to the product's folder in Google Drive.

19. Upload Video Link in Sheet (Google Sheets) — OAuth2. Updates the Google Sheet row (matched by slug) with the video's public URL.

20. Send Mail (Gmail) — OAuth2. Sends an email to a predefined recipient (currently set to [email protected]) with a professional HTML email containing the video link. The email includes a friendly message and a direct link to the video.

Setup Instructions

Required Accounts & Services

• n8n instance (self-hosted or cloud)
• Google Account (for Google Drive and Google Sheets)
• Gmail Account (for sending emails)
• remove.bg Account — Sign up at https://www.remove.bg and get an API key
• Fal.ai Account — Sign up at https://fal.ai and create an API key for the Kling Video model

Credential Configuration

1. Google OAuth2 — Create OAuth2 credentials in Google Cloud Console with access to Google Drive, Google Sheets, and Gmail APIs. Configure the n8n Google OAuth2 credential with your client ID and secret.
2. remove.bg API Key — Create a new "Header Auth" credential in n8n with the header name "X-API-Key" and your remove.bg API key as the value.
3. Fal.ai API Key — Create a new "Header Auth" credential in n8n with the header name "Authorization" and the value "Key YOUR_FAL_API_KEY".
4. Gmail OAuth2 — Use the same Google OAuth2 credential or create a separate one for Gmail.

Configuration Steps

1. Update the Send Mail node's "Send To" field with your desired recipient email address.
2. The Google Sheet ID is hardcoded (18k1Gq2X2J3_cbwJ9XyJoysVuhIpWhgc1cmlTKBnB3Yw). Either use this existing sheet or create your own and update the Document ID in all Google Sheets nodes.
3. The video generation prompt can be customized in the Create video node's body parameters.
4. Adjust the Wait node's duration if video generation typically takes longer or shorter.

Use Cases & Variations

Primary Use Case

E-commerce businesses can use this workflow to automatically generate product videos for their catalog. Simply submit a product photo through the form, and within a few minutes, receive a professional 3D rotating product video ready for use on product pages, social media, or marketing materials.

Possible Adaptations

• Multi-product batch processing — Modify the form to accept multiple files and loop through each one
• Different video styles — Change the prompt in the Create video node to generate different camera movements or backgrounds
• Social media posting — Add nodes to automatically post the video to Instagram, TikTok, or YouTube
• Watermarking — Add an image processing step to overlay a logo or watermark on the video
• Analytics tracking — Extend the Google Sheet to track which products generate the most engagement
• Notification alternatives — Replace Gmail with Slack, Telegram, or SMS notifications
• Different AI video providers — Swap the Kling AI API for RunwayML, Pika Labs, or other video generation services

Customization Tips

• The form can be embedded on any website using an iframe
• The email template can be customized with your brand colors and logo
• The Google Sheet can be used as a CMS to trigger workflows for specific products
• Add error handling nodes to notify you if video generation fails
