DragVideo proposes a novel framework that enables intuitive and accurate drag-style editing of videos while preserving spatio-temporal consistency.
Özet
The paper introduces DragVideo, a framework for performing drag-style video editing. The key highlights are:
DragVideo addresses three main challenges in video editing: 1) how to perform direct and accurate user control in editing, 2) how to execute editings like changing shape, expression, and layout without unsightly distortion and artifacts, and 3) how to maintain spatio-temporal consistency of video after editing.
DragVideo consists of several core components:
Sample-specific LoRA fine-tuning to enhance preservation of personal identity in the edited video.
Propagation of user-provided points and masks throughout the video using Persistent Independent Particles (PIPs) and Track-Anything Model (TAM).
Drag-style video latent optimization using a video-level drag objective function and video diffusion model.
Mutual Self-Attention denoising to ensure consistency between the input and output videos.
Extensive experiments, including quantitative evaluation, qualitative analysis, and user studies, demonstrate that DragVideo outperforms direct extensions of image-based drag editing methods and prompt-based video editing approaches in terms of accuracy, temporal consistency, and visual quality.
