Getting Started: How to Generate an AI Video
From registering an account and grabbing a free API key to generating your first AI video — it takes just a few minutes and no credit card.
Agnes Video Generator runs on Agnes AI's free open platform. Every entry point — the online Demo, the Web Studio or the API — sits on top of the same models: agnes-video-v2.0 for videos and agnes-image-2.1-flash for images, with output up to 720p and a single shot up to 20 seconds long. All you need is one free key to get started.
A typical generation flow
1.Get your free key
Sign up at platform.agnes-ai.com (no credit card needed) and generate your API key from the console. Want more detail? Follow the tutorial link below.
Get a free API key →2.Pick an entry point
Use the online Demo to get publishing right away, the Web Studio when you need richer features like multiple scenes, or read the API docs to integrate into your own application.
3.Write your prompt
Describe the scene, the subject, the motion and the camera with plain text. The more specific your prompt is, the closer the result gets to the picture you have in mind.
4.Generate, wait and download
Submit the job and the video is ready in a few minutes. Preview it, and once you are happy, download the 720p output.
Which entry point should you start from?
All entries share the same free model and the same key, so it all comes down to how you like to work:
Use the Demo online right away
The fastest option: type a prompt and generate videos and images straight in the browser. Great for a first impression.

A richer video suite with scenes, subtitles and more parameters. Perfect when you want to produce something more polished.
Learn more →Integrate into your own application
Call the HTTP API with your key and plug text-to-video generation straight into your product.
API documentation →Self-host everything
Run the whole stack in your own environment and keep full control over your data and processing.
Learn more →Free, with a reasonable rate limit
A single free key is all you need. The free API is limited to 16 calls per minute, and each output can be up to 720p with shots no longer than 20 seconds. That is plenty for everyday experimenting — if you ever hit the cap, just wait a few seconds between requests.
