Abstract: Diffusion Transformer has demonstrated powerful capability and scalability in
generating high-quality images and videos. Further pursuing the unification of
generation and editing tasks has yielded significant progress in the domain of
image content creation. However, due to the intrinsic demands for consistency
across both temporal and spatial dynamics, achieving a unified approach for
video synthesis remains challenging. We introduce VACE, which enables users to
perform Video tasks within an All-in-one framework for Creation and Editing.
These tasks include reference-to-video generation, video-to-video editing, and
masked video-to-video editing. Specifically, we effectively integrate the
requirements of various tasks by organizing video task inputs, such as editing,
reference, and masking, into a unified interface referred to as the Video
Condition Unit (VCU). Furthermore, by utilizing a Context Adapter structure, we
inject different task concepts into the model using formalized representations
of temporal and spatial dimensions, allowing it to handle arbitrary video
synthesis tasks flexibly. Extensive experiments demonstrate that the unified
model of VACE achieves performance on par with task-specific models across
various subtasks. Simultaneously, it enables diverse applications through
versatile task combinations. Project page:
