Watch: The two images below are your first and last frames: the person at the door, then the person sitting by the window. The walk in between is left to the model. The beginning and end are in your hands.A line-art demo that only illustrates the technique, not finished footage.

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

Camera moves that need an exact landing point, transformations and transitions, joining two shots seamlessly.

02

Prompt template

(first frame: the girl at the doorway; last frame: the girl seated in the chair by the window) the girl walks into the room, crosses the living room, and sits in the chair by the window, camera trucking to follow, natural continuous motion, 5 seconds.

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.

(First frame: the delivery rider stands at his front door, hand raised mid-air about to knock. Last frame: the door is open, his mother stands in the doorway, the two looking at each other) The door is pulled open from inside, warm yellow light spreading little by little through the gap onto his face; his mother appears in the doorway and they look at each other without a word. Locked-off camera, 5 seconds, natural, continuous movement.
04

Common pitfalls

  • The two images are too different and the motion in between warps.
  • Light or style differs between the frames and it flickers partway through.
05

Parameter tips

Ideally make the first and last frames by editing the same image; keep the difference within one action or one camera move.
