Through a simple form, users can provide a description, optionally attach an image URL for image-to-video, and choose the video aspect ratio (16:9 or 9:16). The request is then sent to the VietVid.com API, which is polled until the video is complete, and the final video link is returned. This workflow is a cost-effective solution for creators, educators, and businesses to generate personalized videos quickly and easily.\n\n## Pricing Advantage\n- Videos start at only **$0.4 per 8-second clip**.\n- Billing is based on **credit packages**.\n- **No expiration date** on credits—use them whenever you want.\n\n## Prerequisites\n- A VietVid.com account and valid API key: Register at [VietVid.com](https://vietvid.com) to obtain your free or paid key.\n- An active n8n instance (cloud or self-hosted) with HTTP Request and form submission.\n- Basic knowledge of prompt design for better AI results.\n- (Optional) An image URL if you want to generate videos from images."
