Veo 3 Prompt Generator
Built for Veo's native-audio workflow: a shooting-script style prompt with camera, lighting, sound and dialogue in the right order — plus a JSON version when you need one.
Writing prompts for Veo 3
Veo 3 and 3.1 reward prompts that read like a short shooting script. Put the visual story first, then camera and lighting, and finish with sound: Veo generates native audio, so an explicit audio line — ambient sound, a music cue, or one short line of dialogue in quotes — makes a real difference compared with models that are silent by default. Keep clips to a single beat: at 8 seconds, one action done well beats a plot summary.
Working through an API or a structured workflow? This page also emits a JSON version of your prompt with the scene text, camera, lighting, duration and negative prompt as separate fields, ready to adapt to your request payload.
How it works
Video models respond to the same language cinematographers use. Instead of one long ramble, a good prompt answers six questions in order: how big is the shot, who is in it, what are they doing, where are they, how does the camera move, and what do the light and style feel like. This generator asks those questions one at a time and stitches the answers into a single clean paragraph, adding audio direction and technical settings at the end.
A prompt structure that works
| Part | What it controls | Example |
|---|
| Shot size | How much of the scene the viewer sees | close-up, wide shot, aerial shot |
| Subject + action | The story of the clip in one breath | a diver holds still as a whale glides past |
| Setting | Place, time and atmosphere anchors | deep blue open ocean, dawn, night market |
| Camera movement | Energy and point of view | slow push-in feels intimate; a drone flyover feels epic |
| Lighting + style | The look — realism, anime, commercial gloss | golden hour light, hand-drawn anime look |
| Audio + negatives | Sound direction, and what to keep out | ambient sound; avoid morphing and watermarks |
Tips from real generations
- One clear action beats three competing ones. If the subject does everything, the model does nothing well.
- Name the light. “Golden hour” or “neon night” changes the grade more than any style adjective.
- Keep dialogue short — a single short line per clip is what current models handle reliably.
- Iterate one variable at a time: same prompt, new camera move. That is how you learn what each field does.
FAQ
What is an AI video prompt generator?
It turns a rough idea into a structured prompt written in filmmaking language — shot size, camera movement, lighting, style and audio — so AI video models land closer to what you pictured on the first try.
Which models does this work with?
The output is plain English and works with Veo 3 / 3.1, Sora 2, Seedance, MiniMax and similar text-to-video models. Use the model selector to match durations and, for Veo, to get a JSON version for API workflows.
Is it free? Do I need an account?
Yes — free, no account, and nothing you type leaves your browser. The tool runs entirely on your device.
How long should a prompt be?
Roughly 60–150 words. Long enough to cover subject, action, setting, camera, lighting and style; short enough to avoid contradicting yourself.
