Wan2.1 and ATI for Control Video Motion: Draw Your Path, Get Your Video

ATI takes an image and user-drawn motion paths, then generates video following those exact trajectories. Instead of describing movement in text prompts, you draw where things should go.

How it works at a quick high-level:

• Load an image

• Draw motion paths on it using the Spline Editor

• ATI generates video following your paths

• Control objects, people, or camera movement

This replaces older methods that needed separate tools for different motion types. Let's deep dive into details now.

What is ATI?

ATI, or Any Trajectory Instruction, is a new framework for controllable video generation that lets users guide how objects, people, or even the camera move in a video by simply drawing or specifying motion paths (trajectories) on an image. 

Unlike older methods that needed separate tools for different kinds of motion, ATI combines everything into one system: you can control local deformations, full object movements, or camera angles—all at once—by setting keypoints and their paths. These user-defined trajectories are injected into powerful AI video models, ensuring the generated video follows your instructions smoothly and realistically.

ATI makes it easy for anyone to create videos with precise, custom motion, opening up new creative possibilities and giving users much more control over how their videos look and move.
