摘要

我們提出 Vidu S2，其包含 Vidu S2-Avatar，一個即時互動數位角色模型，以及 Vidu S2-Editing，一個即時影片編輯模型。此外，我們探索針對 Vidu S2-Avatar 與 Vidu S2-Editing 的即時空間影片生成之可行性。與 Vidu S1 相比，Vidu S2-Avatar 支援即時 720p 影片生成、可隨時更新的動態參考生成，以及更強的指令遵循能力，例如跳舞。Vidu S2-Editing 支援即時編輯影片串流，包括風格渲染、服裝替換、角色替換與背景替換。實驗顯示，Vidu S2 優於所有基線。可試玩的線上展示位於 https://vidu.com/vidu-stream。

We present Vidu S2, which comprises Vidu S2-Avatar, a real-time interactive digital-character model, and Vidu S2-Editing, a real-time video editing model. Moreover, we explore the feasibility of real-time spatial video generation for both Vidu S2-Avatar and Vidu S2-Editing. Compared with Vidu S1, Vidu S2-Avatar supports real-time 720p video generation, generation with dynamic references that can be updated at any moment, and stronger instruction following, such as dancing. Vidu S2-Editing supports editing a video stream in real time, including style rendering, clothing replacement, character replacement, and background replacement. Experiments show that Vidu S2 outperforms all baselines. A playable online demo is available at https://vidu.com/vidu-stream.
