Gen-2 Motion Brush

Selective area animation tool for AI-generated video in Runway

Visit help.runwayml.com ↗

Motion Brush is a feature in Runway Gen-2 that lets users paint over specific parts of a static image to add targeted movement. Instead of animating an entire scene unpredictably, it confines motion to selected areas like water, clouds, or vehicles.

What it's for

  • Animate specific elements in a still image like running water or rising smoke
  • Add controlled motion to backgrounds while keeping subjects static
  • Direct vehicle or character movement along specific paths in generated clips

Features

  • Brush tool to highlight exact regions of an image for animation
  • Directional motion controls for selected areas
  • Integration within Runway's Gen-2 video generation interface

Pricing

Freemium. Included in Runway subscription tiers, which offer free credits and paid plans
