摘要:
近期视频生成的进步表明,真实音频视觉同步对吸引人的内容创作至关重要。然而,现有视频编辑方法大多忽视音频视觉同步,并缺乏实现精确实例级编辑所需的细粒度空间和时间可控性。在本文中,我们提出了AVI-Edit,一种用于音频同步视频实例编辑的框架。我们提出了一种粒度感知的掩码细化器,通过迭代细化粗略的用户提供的掩码,将其转化为精确的实例级区域。我们进一步设计了一个自反馈音频代理,以精选高质量音频指导,提供细粒度的时间控制。为了促进这一任务,我们还构建了一个大规模数据集,具有实例中心的对应关系和全面的标注。广泛的实验表明,AVI-Edit在视觉质量、条件遵循和音频视觉同步方面均优于最先进的方法。项目页面:https://hjzheng.net/projects/AVI-Edit/.
英文摘要:
Recent advancements in video generation highlight that realistic audio-visual synchronization is crucial for engaging content creation. However, existing video editing methods largely overlook audio-visual synchronization and lack the fine-grained spatial and temporal controllability required for precise instance-level edits. In this paper, we propose AVI-Edit, a framework for audio-sync video instance editing. We propose a granularity-aware mask refiner that iteratively refines coarse user-provided masks into precise instance-level regions. We further design a self-feedback audio agent to curate high-quality audio guidance, providing fine-grained temporal control. To facilitate this task, we additionally construct a large-scale dataset with instance-centric correspondence and comprehensive annotations. Extensive experiments demonstrate that AVI-Edit outperforms state-of-the-art methods in visual quality, condition following, and audio-visual synchronization.
