Veo 3.1 Prompt Generator

Pick a subject, camera move, lighting, and style, add a spoken line, and get a copy-paste prompt structured the way Veo actually wants it. Free. No signup. Runs in your browser.

Keep it under ~20 words. Veo clips are 4 to 8 seconds, so one short sentence lands best.

3 example prompts built with this tool

Copy any of these straight into Veo 3.1 (or any Veo-powered tool) to see the structure in action.

UGC selfie ad (skincare)
A casual selfie-style UGC video that looks self-shot on a phone, not a polished commercial. Subject: a woman in her late 20s with glowing skin holding a small amber serum bottle up next to her face, in a bright bathroom with a mirror behind her. Camera: handheld front-facing selfie camera at arm's length with natural micro-shake and slight reframing, vertical 9:16 composition, the way a real creator films on a phone. Lighting: bright even ring light from the camera position, the classic creator setup, subtle catchlight in the eyes, slightly flat but flattering. Audio: the person looks directly into the lens and says, in a natural conversational tone: "I stopped buying five products when I found this one serum". Accurate lip sync, realistic room tone, no background music. Overall look: realistic phone-camera texture, believable amateur framing, authentic and unstaged. No captions, no subtitles, no on-screen text, no watermarks.
Cinematic hero shot (coffee brand)
A cinematic, film-quality shot with shallow depth of field, filmic color grade, and a soft anamorphic feel. Subject: a barista in a denim apron pouring steamed milk into a ceramic cup, latte art forming in real time, in a sunlit specialty coffee shop with plants and warm wood counters. Camera: slow cinematic dolly-in toward the subject, smooth gimbal movement, gradually tightening the frame. Lighting: warm golden-hour sunlight, long soft shadows, amber highlights, slightly hazy glow. Audio: natural ambient sound only, the hiss of the steam wand and soft cafe murmur, no dialogue, no music. Overall look: 35mm film aesthetic, rich color grade, natural film grain. No captions, no subtitles, no on-screen text, no watermarks.
Studio product spot (fitness app)
A clean studio product video against a simple seamless backdrop, premium commercial look. Subject: a smartphone standing upright showing a fitness app dashboard with a workout streak counter, a resistance band and water bottle arranged beside it, on a matte charcoal surface. Camera: slow continuous orbit around the product on a turntable-style move, even speed throughout. Lighting: soft diffused studio lighting from a large key source, clean and even, minimal shadows, neutral white balance. Audio: a warm, confident voiceover says: "Three workouts a week. That's the whole plan". Subtle ambient room tone underneath, no music. Overall look: crisp commercial polish, accurate product colors, dust-free surfaces. No captions, no subtitles, no on-screen text, no watermarks.

How this generator works

No AI is involved in building the prompt. The tool assembles your inputs into a deterministic template based on the prompt anatomy Google documents for Veo: style first, then subject and setting, then camera, lighting, and audio, ending with negative instructions. Everything runs client-side in your browser, nothing you type is sent to a server.

Why a template instead of AI? Because Veo prompting is mostly a structure problem, not a creativity problem. The most common failure mode is a short, vague prompt like "woman talking about skincare product", which leaves the model to guess the framing, lighting, and audio. A complete paragraph that pins down all six elements gets dramatically more consistent results, and a template pins them down every time.

The 6-part anatomy of a Veo 3.1 prompt

Every prompt this tool produces follows the same order. If you write prompts by hand, keep the same checklist.

1. Style

The first sentence sets the whole look: UGC selfie, cinematic film, or studio commercial. Veo weighs early words heavily, so the style goes first.

2. Subject + setting

Who or what is on screen, what they are doing, and where. Specific beats generic: 'a woman in her late 20s holding an amber serum bottle' outperforms 'a person with a product'.

3. Camera movement

Veo understands real cinematography language: locked-off static, handheld micro-shake, slow dolly-in, orbit. Naming one movement keeps the shot coherent; naming none gets you random drift.

4. Lighting

Lighting is the fastest way to control mood: natural window light, golden hour, soft studio, ring light, low-key. One clear lighting sentence prevents the flat 'AI look'.

5. Audio + dialogue

Veo 3.1 generates native audio. Put the spoken line in quotation marks, describe the tone, and say 'no background music' if you plan to add your own track in the edit.

6. Negative instructions

End by ruling out what you do not want: no captions, no subtitles, no on-screen text, no watermarks. Ad accounts get burned by baked-in gibberish text more than anything else.

Frequently asked questions

What is a Veo 3 prompt generator?

It is a tool that turns a few plain-English choices (subject, setting, camera movement, lighting, style, dialogue) into one well-structured prompt for Google's Veo video model. Veo responds much better to a single descriptive paragraph that covers cinematography and audio than to a short vague request, and this generator builds that paragraph for you.

How do I write good Veo 3.1 prompts for ads?

Cover six things in one paragraph: the style of footage (UGC selfie, cinematic, or studio), the subject and what they are doing, the setting, the camera movement, the lighting, and the audio including any spoken line in quotation marks. For ads, also state what you do NOT want, like captions, subtitles, or on-screen text, so you can add your own in the edit.

Does Veo 3.1 generate speech and lip sync?

Yes. Veo 3.1 generates native audio, including spoken dialogue with lip sync, ambient sound, and effects. Put the exact line in quotation marks inside the prompt and describe the delivery, for example 'says in a natural conversational tone'. Keep the line under roughly 20 words since clips are 4 to 8 seconds long.

What is the difference between Veo 3 and Veo 3.1 prompts?

The prompt structure is the same. Veo 3.1 improved audio quality, prompt adherence, and image-to-video control, so well-structured prompts follow instructions more reliably than on Veo 3. Everything this generator produces works on both versions and on tools built on top of Veo.

Is this Veo prompt generator free?

Yes. It runs entirely in your browser with no signup and no limits. The prompt is composed from a template on your device, nothing is sent to a server. The paid product is UGC Vids AI itself, where you can run the prompt on Veo 3.1 and other models.

Can I use Veo 3.1 to make UGC-style ads?

Yes, and it is one of the most common commercial uses. The trick is telling Veo the footage should look self-shot: front-facing selfie camera at arm's length, handheld shake, vertical 9:16 framing, ring light or window light, conversational delivery. The UGC selfie preset in this generator writes all of that for you.

You have the prompt. Now render it.
