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

Grok Imagine Video 1.5 is xAI’s improved image-to-video model, built for better quality at faster speeds. Now generally available on the Imagine API as grok-imagine-video-1.5, it gives creators and developers a way to start from an image, describe the motion, and choose the resolution and duration for the generated video. Grok Imagine Video 1.5 and Video 1.5 Fast are described as xAI’s best image-to-video models yet, with better motion, better physics, better audio, and faster generation for real creative work. Audio and speech are generated in the same pass as the visuals, so sound effects, ambience, and dialogue land on the action, while speech is clearer and better synchronized. Motion and physics are also improved, helping movement hold together across the length of a clip with fewer warps and more believable weight and momentum. Grok Imagine Video 1.5 Fast almost doubles generation speed, producing 6-second, 720p videos in about 25 seconds.
