Erase the Mark, Preserve the Motion: Temporally Consistent Removal of Video Watermarks

PoseRegen is a new framework for removing video watermarks while maintaining temporal consistency and motion fidelity. It first applies a shared viewpoint transformation to break watermark patterns, then reconstructs the sequence with a pose‑conditioned video model and Flow Matching supervision to preserve identity and background. The method also includes a Pose‑Conditioned Motion Consistency Adapter to keep body‑part trajectories stable, achieving near‑random watermark bit accuracy and outperforming baselines on motion metrics.

TKCAM: Text and Keyframe to Camera Trajectory Generation

TKCAM is a new framework for generating controllable camera motion conditioned on text and sparse keyframes, using a 12‑dimensional kinematic representation and a two‑stage masked transformer with residual vector quantization. It allows users to provide free‑form text prompts and RGB observations at selected timestamps, enabling temporally localized visual guidance for coherent trajectory synthesis. The authors also introduce the RealEstate10K‑Cap dataset and a Universal CLaTr Evaluator, showing that TKCAM outperforms recent baselines on FID, text‑motion matching, and retrieval metrics.

CameraEditor: Camera-Controlled Image Editing via Video-Prior Sequential Modeling

CameraEditor is a new framework that transforms camera-controlled image editing into a temporal sequence prediction problem. By using video diffusion models, it incorporates a geometric perception module and dynamic reference routing to create precise visual references through dynamic panorama cropping. The method also inserts intermediate transition frames to handle large perspective shifts, maintaining content identity and spatial coherence, and is evaluated on a dataset of 5,760 instances with a benchmark of 462 test cases, achieving state‑of‑the‑art performance.
