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

FramePack AI revolutionizes video creation by enabling the generation of long, high-quality videos on consumer GPUs with just 6 GB of VRAM, using smart frame compression and bi-directional sampling to maintain constant computational load regardless of video length while avoiding drift and preserving visual fidelity. Key innovations include fixed context length to compress frames by importance, progressive frame compression for optimal memory use, and anti-drifting sampling to prevent error accumulation. Fully compatible with existing pretrained video diffusion models, FramePack accelerates training with large batch support and integrates seamlessly via fine-tuning under an Apache 2.0 open source license. Its user-friendly workflow lets creators upload an image or initial frame, set preferences for length, frame rate, and style, generate frames progressively, and preview or download final animations in real time.
