AVAI Video Prompt

Free AI Video Prompt Generator

An AI video prompt generator turns a plain idea into a structured prompt a video model can actually follow. A video prompt is a written instruction that spells out the subject, the action, the camera movement, the lighting and the mood — and the difference between a vague one-liner and a structured prompt is usually the difference between a throwaway clip and a publishable video.

Type your idea below, choose a category, your video tool, a duration, a mood and a camera style, and this free tool assembles a starter prompt for you: a scene paragraph, timestamped beats, a copy-ready version formatted for your tool, and a negative prompt that keeps the usual glitches out. It runs in your browser — no signup, no cost, regenerate as many variations as you like.

When a starter prompt is not enough, the library holds 573 complete production packages — full master prompt, voiceover script, image prompts, thumbnail text and an SEO kit for each one. Any single package is $1, Premium is $24/mo, and 6 prompts are free with an account.

One clear subject works best. Leave it blank and we'll use a Animals & Pets example.

Your starter prompt

Built around: a cat running a coffee shop

The scene opens in a miniature pet-sized café with tiny cups and stools, where a cat running a coffee shop is already hard at work on something very important. Friends gather around, watching with deep fascination, and a dramatic yawn nearly derails the whole operation. Shot as an intimate close-up as the camera slowly pushes in, every small detail in sharp focus. Lit with soft, diffused daylight that feels warm and cozy, finished in a bright, warm grade with softly rounded highlights. The tone is pure cute — adorable proportions, gentle movements and heart-melting expressions. Sound: a warm acoustic guitar over cozy room tone — tiny cheerful melodies with soft, happy tones. It ends with everyone posed together like a family portrait. A 10-second vertical video for Veo 3.

Negative prompt

blurry, distorted faces, extra fingers, warped anatomy, flickering frames, morphing objects, text artifacts, watermark, low quality, jittery motion, unnatural physics, deformed paws, unnatural fur

Tip for Veo 3: Veo 3 generates the audio together with the picture, so keep the Audio line — edit it to taste, and put any spoken words in quotation marks. One continuous scene per prompt works best.

Prompt generator questions

Is this prompt generator really free?

Yes. The generator is completely free, needs no signup and no card, and runs entirely in your browser — there is no limit on how many prompts you generate or regenerate. It is our way of letting you feel the difference a structured prompt makes before you ever look at the paid library.

Which AI video tools does it work with?

The generator formats its output for Sora, Veo 3, Runway, Pika and Kling, including a tip specific to the tool you pick. The plain starter-prompt version works in any text-to-video tool, since all of them read the same ingredients: subject, action, camera, lighting and mood.

How is this different from the paid prompt packages?

The generator gives you a single starter prompt built from your own idea — a scene paragraph, timed beats and a negative prompt. The library's paid packages are complete production packages for specific, proven concepts: the full master prompt, a voiceover script, image prompts, thumbnail text and an SEO kit, plus master engines that run an entire series in one niche. A single package is $1, or Premium unlocks all 573 for $24/mo.

Can I use the generated prompts commercially?

Yes — the prompt text this generator creates from your own idea is yours to use, including in commercial videos, client work and ads. The library's own prompt texts carry the license described on our Terms page: free prompts may be used freely including commercially, and premium prompts include commercial use for the videos you generate — you just can't resell or redistribute the prompt texts themselves.

Generated a prompt you love? Publish it properly.

The free generator covers the prompt itself. The library's 573 packages add the voiceover script, thumbnail text and SEO kit around it — $1 per package, or everything for $24/mo.
