Act-two（Video Style Transfer）

Runway’s Latest Generative Motion Capture Tool — Act-Two: Instantly Turn Videos into Animation

With just a performance video and a target character image, you can use Act-Two to capture motion and facial expressions, and “transfer” them onto characters in any style or setting. From full-body movement to subtle facial expressions and flexible gestures, everything is highly replicable. There's no need for expensive motion-capture equipment—just upload your content in a few steps to instantly generate your own high-quality animation.

Note: Generation time depends on the input material, typically 10–20 minutes
Only 16:9 aspect ratio video formats are supported. If the uploaded video dimensions do not meet the requirements, generation will fail and automatic refunds will be processed.
