I want to generate a video with AI.
Every question is optional. The ones marked Recommended matter most.
AI tools invent labels, logos, prices and people. Before you publish, check every detail against the real product, and use only your own brand and people who agreed to appear.
How to write a prompt for an AI video tool
Use this form when you want a short clip from a video tool such as Google Flow, Kling, Runway or Luma. Video tools cannot ask you questions, so there is no “How should the AI start?” choice. Pick “One shot” or “A few shots” at the top.
Why the recommended questions matter
- What happens. One main action per shot. Google’s best practices for Veo warn that chaining several events into a short clip often leads to muddled or incomplete videos.
- Where and when. The setting appears in every maker’s formula, and time of day and weather are part of describing it. See Google’s prompting guide for Veo 3.1 and Kling’s prompt guide.
- How it’s filmed. How close the camera is and how it moves come first in the formulas from Google and Runway. ByteDance’s Seedance guide advises one camera move per shot.
- Look and light. The Seedance guide notes that without a stated style the result can drift toward live-action realism.
- Sound. Most leading tools now generate sound, and the examples in Google’s Veo prompt guide give it its own “Audio:” line. Alibaba’s Wan guide advises writing “No background music” when you want none.
Why labeled prose and not JSON
No maker of a leading video tool recommends JSON prompts. Their examples are plain sentences, sometimes labeled, such as “Audio:”. The evidence that JSON does better is anecdotal: blog posts and practitioner reports, with no published method. Runway’s guide says structure and order matter far less than conveying the idea clearly. So this form writes short labeled prose that every tool can read.
A worked example
A bakery wants a short clip of its baker at dawn, with one spoken line. The form composes:
One continuous shot.
Medium close-up, slow push in: a baker in her fifties with flour on her forearms lifts a tray of golden croissants out of a deck oven, sets it on the steel counter, then looks up at the camera and smiles.
Setting: a tiny corner bakery just before sunrise; steam rises from the tray; the street outside the window is still dark blue.
Style: Realistic film. Documentary feel. Warm orange light from the oven against cool blue light from the window. Calm, welcoming mood.
Audio: the oven door creaks open, the metal tray clatters onto the counter, a low room hum. No background music.
Dialogue: the baker, warm and a little tired, says: "Fresh out. Come and get them."
Avoid: subtitles, on-screen text, logos, watermarks.
Length, shape and sound on or off are set in your video tool’s own controls, not in the prompt, which is why they sit in a separate card.
What the form adds for you
It opens with “One continuous shot.” to discourage unwanted cuts, as Alibaba’s Wan guide suggests, and ends by excluding subtitles, on-screen text, logos and watermarks, following the Seedance guide, which reports stray subtitles even when none were asked for.
