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

Seaweed is a foundational AI model for video generation developed by ByteDance. It utilizes a diffusion transformer architecture with approximately 7 billion parameters, trained on a compute equivalent to 1,000 H100 GPUs. Seaweed learns world representations from vast multi-modal data, including video, image, and text, enabling it to create videos of various resolutions, aspect ratios, and durations from text descriptions. It excels at generating lifelike human characters exhibiting diverse actions, gestures, and emotions, as well as a wide variety of landscapes with intricate detail and dynamic composition. Seaweed offers enhanced controls, allowing users to generate videos from images by providing an initial frame to guide consistent motion and style throughout the video. It can also condition on both the first and last frames to create transition videos, and be fine-tuned to generate videos based on reference images.
