How Does Runway Motion Brush AI Work?


One of the most powerful tools, Runway Motion Brush AI, can be used to create various effects for creative works. This tool allows artists, filmmakers and anyone else to create visually stunning images and videos. It also offers the opportunity to explore its possibilities and experience the potential of AI-driven creativity.

This tool is relatively easy to use with a simple image or video editor user interface, which can be used for a variety of tasks such as animating people and more. The latest addition allows users to add motion to static images by analyzing and manipulating image data, transforming still images into captivating videos.

What is Runway Motion Brush AI?

This is a tool that allows users to control the movement of objects in images and videos using a technique called optical flow. It generates new images or videos in which the objects move as specified by the users.

It is used to track the movement of objects from the source image or video using the Motion Brush AI. Users can draw lines that indicate desired object movements, expanding its versatility beyond adding movement to static images. This facilitates rotoscoping, allowing creators to isolate and manipulate specific elements within an image.

  • Optical Flow: Motion Brush AI extracts optical flow from image or video sources, creating a 2D vector field in which vectors represent the displacement of corresponding points in the previous frame.
  • User input: Paint strokes on images or videos to indicate the desired movement of the object, with vectors responding to the desired movement of corresponding points.
  • Motion Synthesis: Synthesize the object’s motion as specified by users based on the motion field.
  • Retiming: Can be used to slow down or speed up the movement of an object in images and videos.
  • Rotoscoping: This can be used to isolate objects from their background.
  • Animation: Can animate images and videos to create characters and bring still images to life.

With these features and tools, you can use Runway Motion Brush AI for music videos, short films, or commercial projects. In addition, AI helps users with creative effects, slow motion, fast motion and rotoscoping. Runway Motion Brush allows users to add controlled motion to their AI-generated images and videos.

  • Motion Brush goes beyond simple animation with extensive features to enhance creativity and visual storytelling. Allows users to generate images using prompts via Gen-2 Style presets and fine-tune camera movements.
  • Brush and camera controls enable seamless integration of camera movements, such as zooming and panning, with object movement, creating dynamic and engaging compositions.
  • The user interface is easy to use for editing images or videos.
  • The Gen-2 Update brings new style presets and updates to camera controls, accessible via a credits-based system. Users must purchase credits to simplify the creative process and add visual flair.
