About

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.

About

OmniHuman 2.0 is an advanced AI-powered image-driven video avatar model that transforms a single image and an audio track into expressive, high-quality character animations. It generates realistic movements that align with speech rhythm, prosody, and semantic content, synchronizing lip movements, emotions, and gestures with audio. Optional text prompts provide precise control over character actions, object generation, camera movements, and scene interactions. Its cinematic emotional expression interprets audio context to produce natural gestures, authentic emotional shifts, and digital actors with a full dramatic range. The model supports rhythmic performances, creating digital singers with expressive motion, natural pauses, and adaptability across musical genres. Multi-person scene capabilities enable dynamic character interactions, while support for animals, cartoons, 3D styles, and non-humanoid subjects expands creative possibilities.
