4DAnyone Reconstructs Dynamic Humans from Casual Monocular Video

4DAnyone turns an uncalibrated monocular human video into reconstruction-ready, multiview-consistent videos and then lifts them into a 4D Gaussian Splatting representation. Its main contribution is a pair of context-management mechanisms designed to keep many generated views structurally and visually aligned.

O-VAD shifts industrial video anomaly detection from clip-level viewing to object-level reasoning

O-VAD is a training-free framework for industrial video anomaly detection that tracks objects through time and reasons over their state trajectories. Its central claim is that frontier VLMs often fail in industrial settings because they are not given object-level evidence.

Closing the Loop: A Training-Free Fix for Revisit Consistency in Generative Rendering

The paper tackles a practical weakness in long-horizon generative rendering: when a camera returns to a previously seen place, an autoregressive video model may redraw it differently. The proposed method restores historical latent chunks and uses 3D correspondences to guide attention, without post-training.

SANA-Video 2.0: Hybrid Attention for Faster High-Resolution Video Generation

SANA-Video 2.0 proposes a hybrid video diffusion Transformer that keeps most of the efficiency benefits of linear attention while periodically restoring full softmax interactions. The paper reports competitive quality on a single H100, with notable speedups for longer and higher-resolution video generation.
