Veo 3 Video Generator via VietVid.com API (n8n)

Overview

This workflow leverages the VietVid.com Veo3 model to generate AI videos from simple text descriptions or optional images.
Users interact via a form interface, inputting a prompt (e.g., a scene description), choosing aspect ratio and model, then the system automatically submits the request to the VietVid API, monitors the generation status in real time, and retrieves the final video output.

It’s ideal for content creators, marketers, and developers exploring text-to-video AI creation, supporting intelligent video generation with minimal setup.

Prerequisites

• A VietVid.com account and API key: Register at VietVid.com to obtain your free or paid API key.
• An active n8n instance (cloud or self-hosted) with HTTP Request, Wait, and form submission capabilities.
• Basic knowledge of AI prompts for video generation to achieve optimal results.

Setup Instructions

1. Obtain API Key

• Register at VietVid.com and generate your API key.
• Store it securely—do not share publicly.

2. Configure the Form

• In the Form Trigger node, ensure the following fields are available:
  • text_prompt — video description (e.g., “A serene mountain landscape at sunset with birds flying”)
  • ImageURL [optional] — optional image input for image-to-video
  • api_Token — your VietVid API key
  • aspect_Ratio [16:9,9:16] — dropdown to select ratio
  • model — choose between veo3 and veo3_fast

3. Test the Workflow

• Click Execute Workflow in n8n.
• Access the generated form URL.
• Submit your prompt, API key, and options.
• The workflow will poll the VietVid API every 10 seconds until the video is ready.

4. Handle Outputs

• The final Set node formats and displays the video links:
  • 720p_link — always available when ready.
  • 1080p_link — available only for 16:9 aspect ratio.

Customization Tips

• Enhance prompts: Add details like style (realistic, cinematic, animated), duration, actions, and camera/lighting for better results.
• Stability: Fix the seeds value (e.g., 50000) for more consistent characters.
• Webhook Response: Add a Webhook Response node to return a clean JSON payload for frontend integrations.
• Adjust polling delay: Modify Wait node (8–15s) if needed to balance speed vs. API calls.
