Act-Two enables animation of any character by transferring movements, expressions, and speech from a driving performance video onto a static image or reference video of your character. By selecting the Gen‑4 Video model and then the Act‑Two icon in Runway’s web interface, you supply two inputs; a performance video of an actor enacting your desired scene and a character input (either a single image or a video clip), and optionally enable gesture control to map hand and body movements onto character images. Act‑Two automatically adds environmental and camera motion to still images, supports a range of angles, non‑human subjects, and artistic styles, and retains original scene dynamics when using character videos (though with facial rather than full‑body gesture mapping). Users can adjust facial expressiveness on a sliding scale to balance natural motion with character consistency, preview results in real time, and generate high‑resolution clips up to 30 seconds long.

Wan2.2 Animate is a specialized module within the Wan video generation framework designed for high-fidelity character animation and character replacement, enabling users to transform static images into dynamic videos or swap subjects within existing footage while preserving realism and motion consistency. It works by taking two primary inputs: a reference image that defines the character’s appearance and a reference video that provides motion, expressions, and scene context. Using this combination, it can animate a still character by replicating body movements, gestures, and facial expressions from the source video, or replace the original subject in a video while maintaining the original lighting, camera movement, and environment for seamless integration. It relies on advanced techniques such as spatially aligned skeleton signals and implicit facial feature extraction to accurately reproduce motion and expressions.
