  Video inpainting has been challenged by complex scenarios like large
movements and low-light conditions. Current methods, including emerging
diffusion models, face limitations in quality and efficiency. This paper
introduces the Flow-Guided Diffusion model for Video Inpainting (FGDVI), a
novel approach that significantly enhances temporal consistency and inpainting
quality via reusing an off-the-shelf image generation diffusion model. We
employ optical flow for precise one-step latent propagation and introduces a
model-agnostic flow-guided latent interpolation technique. This technique
expedites denoising, seamlessly integrating with any Video Diffusion Model
(VDM) without additional training. Our FGDVI demonstrates a remarkable 10%
improvement in flow warping error E_warp over existing state-of-the-art
methods. Our comprehensive experiments validate superior performance of FGDVI,
offering a promising direction for advanced video inpainting. The code and
detailed results will be publicly available in
