摘要

我们提出了 Vidu S2，它包含 Vidu S2-Avatar 和 Vidu S2-Editing 两部分：前者是实时交互式数字人模型，后者是实时视频编辑模型。此外，我们探索了 Vidu S2-Avatar 和 Vidu S2-Editing 进行实时空间视频生成的可行性。与 Vidu S1 相比，Vidu S2-Avatar 支持实时 720p 视频生成、可随时更新的动态参考生成，以及更强的指令遵循能力（例如跳舞）。Vidu S2-Editing 支持实时编辑视频流，包括风格渲染、服装替换、角色替换和背景替换。实验表明，Vidu S2 优于所有基线。可在线试玩的演示见 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.
