Watch: On the left is a still made first with an image model; on the right is what it looks like after a video model takes it: the composition and person are unchanged, only the curtain stirs in the wind and the person slowly turns her head. The prompt only says how it moves.A line-art demo that only illustrates the technique, not finished footage.

Image-to-Video图生视频

Make the image with an image model first, then have a video model bring it to life. Far more controllable than going straight from text to video.

This is a step in making a film, not a visual technique. For the whole process, see Make an AI short from scratch.

Prompt templates are written from how generation models usually behave and have not yet been verified one by one with real generations. “Common pitfalls” are judgment from experience, not official limits.

01

When to use it

Shots that need exact composition, characters and style; recommended for nearly every narrative shot.

02

Prompt template

(after uploading the first frame) the girl slowly turns her head toward the window, the wind lifting the curtain and her hair, camera slowly pushes in, everything else unchanged, 4 seconds.
03

Sample prompt · generate a video directly

The technique comes first, followed by the scene, action, performance and duration. Paste it straight into a video model and swap in your own characters and plot.

(Upload the first frame: a girl sitting at a desk by the window, the desk lamp on) The girl stops writing and slowly turns her head toward the window; the curtain lifts gently in the wind and a few snowflakes drift in. The camera slowly pushes in to her profile; everything else stays the same. 4 seconds.
04

Common pitfalls

  • The prompt describes the whole scene again and the model changes the original image.
  • Asking for too many actions breaks the image.
  • Flaws in the first frame (fingers, text) become more obvious once it moves.
05

Parameter tips

An image-to-video prompt only describes how things move: the character's action, camera movement, changes in the environment.
