  Diffusion-based methods can generate realistic images and videos, but they
struggle to edit existing objects in a video while preserving their appearance
over time. This prevents diffusion models from being applied to natural video
editing in practical scenarios. In this paper, we tackle this problem by
introducing temporal dependency to existing text-driven diffusion models, which
allows them to generate consistent appearance for the edited objects.
Specifically, we develop a novel inter-frame propagation mechanism for
diffusion video editing, which leverages the concept of layered representations
to propagate the appearance information from one frame to the next. We then
build up a text-driven video editing framework based on this mechanism, namely
StableVideo, which can achieve consistency-aware video editing. Extensive
experiments demonstrate the strong editing capability of our approach. Compared
with state-of-the-art video editing methods, our approach shows superior
qualitative and quantitative results. Our code is available at
