Abstract: Controllable video generation has gained significant attention in recent
years. However, two main limitations persist: Firstly, most existing works
focus on either text, image, or trajectory-based control, leading to an
inability to achieve fine-grained control in videos. Secondly, trajectory
control research is still in its early stages, with most experiments being
conducted on simple datasets like Human3.6M. This constraint limits the models'
capability to process open-domain images and effectively handle complex curved
trajectories. In this paper, we propose DragNUWA, an open-domain
diffusion-based video generation model. To tackle the issue of insufficient
control granularity in existing works, we simultaneously introduce text, image,
and trajectory information to provide fine-grained control over video content
from semantic, spatial, and temporal perspectives. To resolve the problem of
limited open-domain trajectory control in current research, We propose
trajectory modeling with three aspects: a Trajectory Sampler (TS) to enable
open-domain control of arbitrary trajectories, a Multiscale Fusion (MF) to
control trajectories in different granularities, and an Adaptive Training (AT)
strategy to generate consistent videos following trajectories. Our experiments
validate the effectiveness of DragNUWA, demonstrating its superior performance
in fine-grained control in video generation. The homepage link is
