Core Viewpoint - The article discusses the development of Sketch3DVE, a novel method for 3D scene video editing that allows users to manipulate videos using simple sketches, enhancing creativity and personalization in video content creation [3][22]. Part 1: Background - Recent advancements in video generation models have significantly improved text-to-video and image-to-video generation, with a focus on precise control over camera trajectories due to its important application prospects [6]. - Existing methods for video editing are categorized into two types: one directly uses camera parameters as model inputs, while the other constructs explicit 3D representations from single images to render new perspective images [8][9]. - Despite these advancements, editing real videos with significant camera motion remains a challenge, as video editing requires maintaining original motion patterns and local features while synthesizing new content [8][9]. Part 2: Algorithm Principles - Users begin by selecting the first frame of a 3D scene video, marking the editing area with a mask and drawing a sketch to specify the geometry of new objects [12]. - The system employs the MagicQuill image editing algorithm to process the first frame, generating the edited result, and utilizes the DUSt3R algorithm for 3D reconstruction to analyze the entire input video [13]. - A 3D mask propagation algorithm is designed to accurately transfer the mask from the first frame to subsequent frames, ensuring consistency across different perspectives [14]. - The final video generation model integrates edited images, multi-view videos, and original input videos to produce a scene-edited video with precise 3D consistency [14]. Part 3: Effect Demonstration - The method allows users to create high-quality 3D scene video edits, enabling operations such as adding, removing, and replacing objects while maintaining good 3D consistency [16]. - The approach can handle complex scenarios involving shadows and reflections, producing reasonable editing results due to training on real video datasets [17]. - Users can also edit the first frame using image completion methods, demonstrating the versatility of the system in generating realistic 3D scene video edits [19]. - Sketch3DVE offers an effective solution to traditional model insertion challenges, allowing for personalized 3D object generation and high-fidelity scene video editing without requiring extensive expertise [22].
