AI Video Prompt Generator

Type a subject, pick a camera move and a style, and this free tool builds a clean, ready-to-paste AI video prompt for you. It follows the same structure used by experienced creators: camera first, one clear action, then setting, lighting, and format — the order that gets usable clips on the first try instead of the fifth.

The generator is completely free, needs no sign-up, and runs right here in your browser. The prompts it creates work with all the major AI video tools, including Google Flow (Veo), Runway, Kling AI, Luma Dream Machine, and Pika.

How to use

1. Pick your AI video platform and describe your subject and its main action.
2. Choose the shot type, camera movement, lighting, style, duration, and aspect ratio — or tap a preset below to fill everything in.
3. Click Generate prompt and copy the main prompt and the negative prompt.
4. Paste both into your AI video tool, generate, and adjust one detail at a time if you want a variation.

Main prompt

Negative prompt

One action per clip. If your scene has two big actions — a character running and a building exploding — split it into two clips and generate them back to back. Short clips with one action almost always come out cleaner than one long clip with three.

Tips for prompts that work first try

• Put the camera first. The opening words of a prompt carry the most weight, so lead with the shot and the camera movement, not the subject.
• One action per clip. A 5–10 second clip can do one thing well. Give it a second job and both jobs usually come out muddy.
• Describe physics naturally. Words like “dangling,” “floating,” “sliding,” or “swaying gently” tell the model how things should move, so motion looks believable instead of stiff.
• Keep it short. A tight prompt of a few clear sentences beats a long wish list. Every extra detail competes with the ones that matter.
• Always use a negative prompt. Listing what you do not want — subtitles, watermarks, extra fingers, flicker — quietly removes the most common AI video defects before they happen.

Frequently asked questions

Is it free?

Yes. The generator is free to use as often as you like, with no sign-up and no account. It runs entirely in your browser, so nothing you type is sent anywhere.

Which AI video tools does it work with?

The prompts are written in plain, structured English, so they work in any text-to-video tool. The platform picker adjusts the format line for Google Flow / Veo, Runway, Kling AI, Luma Dream Machine, and Pika — and the “Any tool” option keeps the prompt fully generic.

What is a negative prompt?

A negative prompt is a short list of things you want the model to leave out — things like subtitles, logos, watermarks, distorted hands, extra fingers, and flicker. Most AI video tools have a dedicated negative prompt field; if yours does not, you can paste the list at the end of your main prompt instead.

How long should a video prompt be?

Shorter than most people think. For a single clip, a few sentences covering the camera, one action, the setting, the lighting, and the style are usually enough. If your prompt needs a second paragraph, the scene is probably trying to do too much — split it into two clips.

Can I use the generated prompts commercially?

The prompts this tool writes are yours to use, including for commercial projects. Whether the videos you create with them can be used commercially depends on the terms of the AI video tool and the plan you are on, so check that tool’s current terms before publishing client or monetized work.
