Vidu S2 introduces real-time avatar and video-editing models for live interaction and stream transformation

What changed

Vidu has added two real-time S2 models to its API. S2-Avatar supports voice interaction and complex motion, with reference images for product interaction, outfit changes and background replacement; S2-Editing uses style, clothing, character and background references to modify an incoming video stream in real time. The update notice describes capabilities but does not provide independent third-party quality validation.
