MotionStream: Real-Time Video Generation with Interactive Motion Controls

Joonghyuk Shin, Zhengqi Li, Richard Zhang +4

Current motion-conditioned video generation methods suffer from prohibitive latency (minutes per video) and non-causal processing that prevents real-time interaction. We present Mo…

Causality in Video Diffusers is Separable from Denoising

Xingjian Bai, Guande He, Zhengqi Li +3

Causality -- referring to temporal, uni-directional cause-effect relationships between components -- underlies many complex generative processes, including videos, language, and ro…

Flowing from Reasoning to Motion: Learning 3D Hand Trajectory Prediction from Egocentric Human Interaction Videos

Mingfei Chen, Yifan Wang, Zhengqin Li +10

Prior works on 3D hand trajectory prediction are constrained by datasets that decouple motion from semantic supervision and by models that weakly link reasoning and action. To addr…

Self-Evaluation Unlocks Any-Step Text-to-Image Generation

Xin Yu, Xiaojuan Qi, Zhengqi Li +6

We introduce the Self-Evaluating Model (Self-E), a novel, from-scratch training approach for text-to-image generation that supports any-step inference. Self-E learns from data simi…

Generative Video Motion Editing with 3D Point Tracks

Yao-Chih Lee, Zhoutong Zhang, Jiahui Huang +5

Camera and object motions are central to a video's narrative. However, precisely editing these captured motions remains a significant challenge, especially under complex object mov…

Self Forcing: Bridging the Train-Test Gap in Autoregressive Video Diffusion

Xun Huang, Zhengqi Li, Guande He +2

We introduce Self Forcing, a novel training paradigm for autoregressive video diffusion models. It addresses the longstanding issue of exposure bias, where models trained on ground…
