Video Object Composition

Video object composition aims to seamlessly integrate objects from different video sources into a coherent and realistic composite video, preserving motion and identity consistency. Recent research heavily utilizes pre-trained diffusion models, often employing techniques like attention mechanisms and feature injections to manage inter-object interactions and ensure temporal coherence across frames. These training-free or zero-shot approaches address limitations of previous methods, particularly in handling complex scenes and significant semantic differences between source videos. This field is advancing video editing capabilities with implications for film production, special effects, and other applications requiring sophisticated video manipulation.
