Free AI Video Prompt Generator

Turn an idea or reference image into a video prompt with subject motion, camera movement, pacing and shot timing for Seedance, Kling, Wan or Veo.

Free to try · No sign-up required

A video prompt needs more than a description of a still frame. Build a shot around one clear action, a camera move, and a beginning and ending that fit the clip duration.

Your prompt

Your generated prompt will appear here. Edit the text, copy it, then use it with your chosen model.

How it works

  1. Describe the scene, or add a reference image and describe what should move.
  2. Choose a target model, duration, aspect ratio and visual style.
  3. Generate a shot prompt, adjust the timing, and use it with your video model.

Questions & answers

Does this tool generate a video?

It generates prompt text. Video generation is a separate action on the chosen model page and is billed to your account according to the selected route.

Will every model support my chosen duration?

The duration is a planning target for the prompt, not a capability guarantee. Check the selected model's supported duration, aspect ratio and reference inputs before submitting a video job.
