Alibaba Drops Wan2.2-S2V: Speech-to-Video Model
Alibaba has unveiled Wan2.2-S2V, an open-source speech-to-video (S2V) AI model that transforms static images and audio clips into lifelike, film-quality animated avatars capable of speaking, singing, and performing.
Key Features
Animation & Performance Capabilities: The model supports a variety of framing options—portrait, bust, and full-body perspectives and enables expressive, natural animations from dialogue to musical performances.
Versatile Character Support: Beyond human avatars, the model supports a diverse range of figures, including cartoons, animals, and stylized characters.
This flexibility makes it suitable for various creative applications, from entertainment content to educational materials.
Model Architecture: The S2V-14B model features 14 billion parameters and utilizes advanced frame processing techniques that compress historical animation frames of arbitrary length into a single, compact latent representation.
This innovative approach significantly reduces computational overhead while enabling stable long-video generation.
Technical Innovation for Long Videos: By leveraging voice-driven local motion and text-guided global control, plus a smart frame-compression method, the model minimizes computational load while maintaining stable long-video generation.
High-Quality Output: The model delivers 480p and 720p resolution outputs, making it adaptable for both quick social-media clips and more refined professional content.
Trained on Industry-Grade Visual Data: Alibaba’s team assembled a large-scale audiovisual dataset tailored to film and television standards. This powering enables precise, story-driven visual expression.
