AI Short Video Prompt Generator

Plan a focused 9:16 clip for TikTok, Instagram Reels or YouTube Shorts with clear action, camera movement and visual continuity.

Build your video prompt

Your idea stays in this browser. Nothing is uploaded or saved.

Your prompt

Better first generations: keep one main action per clip. Complex stories are more reliable when generated as separate shots and edited together.

Three rules for cleaner AI video

Describe motion

Say what physically changes over time. A visual style alone does not tell a video model what should happen.

Protect continuity

Repeat the important details—subject, wardrobe, objects and light—so they remain stable from start to finish.

Design the ending

A held final frame, hero shot or seamless loop gives the clip a deliberate finish.

Frequently asked questions

Does this generate the actual video?

No. It creates a detailed prompt you can paste into your preferred AI video generator.

Why does the prompt avoid text?

Generated lettering can flicker or change between frames. Add captions and calls to action afterward in your video editor.

Can I use the same prompt on every platform?

The 9:16 framing works across major short-form platforms, but confirm each platform’s current duration, resolution and advertising requirements before publishing.
