• Abstract summary: Video editing approaches that rely on dense correspondences are ineffective when the target edit involves a shape change. We introduce the VideoSwap framework, inspired by our observation that only a small number of semantic points are necessary to align the subject's motion trajectory and modify its shape. Extensive experiments demonstrate state-of-the-art video subject swapping results across a variety of real-world videos.

• Abstract: Current diffusion-based video editing primarily focuses on structure-preserved editing by utilizing various dense correspondences to ensure temporal consistency and motion alignment. However, these approaches are often ineffective when the target edit involves a shape change. To embark on video editing with shape change, we explore customized video subject swapping in this work, where we aim to replace the main subject in a source video with a target subject having a distinct identity and potentially different shape. In contrast to previous methods that rely on dense correspondences, we introduce the VideoSwap framework that exploits semantic point correspondences, inspired by our observation that only a small number of semantic points are necessary to align the subject's motion trajectory and modify its shape. We also introduce various user-point interactions (\eg, removing points and dragging points) to address various semantic point correspondence. Extensive experiments demonstrate state-of-the-art video subject swapping results across a variety of real-world videos.

To precisely modify the contents of the video, we employ a new video-level motion supervision to update the features of the video.

  Previous works usually work well on trivial and consistent shapes, and easily collapse on a difficult target that has a largely different body shape from the original one. We propose motion personalization that isolates the motion from a single source video and then modifies the protagonist accordingly. We also regulate the motion word to attend to proper motion-related areas by introducing a novel pseudo optical flow.

  We introduce optical flow into the attention module in the diffusion model's U-Net to address the inconsistency issue for text-to-video editing. Our method, FLATTEN, enforces the patches on the same flow path across different frames to attend to each other in the attention module. Results on existing text-to-video editing benchmarks show that our proposed method achieves the new state-of-the-art performance.
