Abstract: Modern video generation models like Sora have achieved remarkable success in producing high-quality videos.However, a significant limitation is their inability to offer interactive control to users, a feature that promises to open up unprecedented applications and creativity. In this work, we introduce the first solution to equip diffusion-based video generation models with spatio-temporal control. We present Peekaboo, a novel masked attention module, which seamlessly integrates with current video generation models offering control without the need for additional training or inference overhead. To facilitate future research, we also introduce a comprehensive benchmark for interactive video generation. This benchmark offers a standardized framework for the community to assess the efficacy of emerging interactive video generation models.Our extensive qualitative and quantitative assessments reveal that Peekaboo achieves up to a $3.8\times$ improvement in mIoU over baseline models, all while maintaining the same latency. Code and benchmark are available on the webpage.
