AI video prompt builder

Video models need more than a subject: where the camera is, how it moves, the light and the pace. Say what happens, tap a few options, and our AI writes the rest.

How to use it

  1. Describe who or what is on screen, what happens, and where.
  2. Tap a camera move, a look and a length. Skip any you don't care about.
  3. Pick your video model, so the prompt is written for it.
  4. Tap Make my prompt, log in with one click, and paste the prompt into your video tool.

Tips

  • One action per clip. Asking for three things to happen in 8 seconds usually blurs all of them.
  • A slow push in or a static shot gives the cleanest motion. Fast moves are where clips break.
  • Veo and Sora can make sound. Mention the sounds you want in the scene and they'll be written in.
  • Most tools also have their own length and ratio settings. Set those to match the prompt.

Frequently asked questions

Any that take a text prompt, including OpenAI Sora, Google Veo, Runway, Kling, Luma and Pika. Pick one and the prompt is written for it.

What makes a good AI video prompt?

A clear shot and camera movement, one subject doing one thing, a setting, a look and the pace. Short, concrete words beat long descriptions.

Why do I need to log in?
