DESM: Story-Level Cartoon Video Generation

The Alibaba and ByteDance models represent a major new competitive frontier, but the paper (from Daniel Gao) introduces DESM, a training-free framework that generates a high-quality

FrameBridge: Efficient Video-to-Video Translation

FrameBridge tackles a major pain point in T2V conditioning. It provides a plug-and-play method for video models to learn from and react to temporal control signals (like user edits or external motion data) using just 1-2 reference frames, making consistent, controllable video editing much more practical.

Multi-Entity Self-Rectification for T2I

This paper attacks the notoriously difficult problem of generating high-quality images with multiple characters and complex spatial relationships. It introduces a novel self-rectifying mechanism that significantly improves prompt fidelity for instructive, detail-rich T2I generation.

Hierarchical Counterfactuals for Text-Grounded Video Generation

Most T2V models struggle with long, complex prompts. This paper introduces a hierarchical visual-semantic counterfactual learning approach to explicitly train models to better ground their generation in the detailed text instructions, a key step toward reliable cinematic control.

Video Scaling Laws: Depth vs. Width in DiTs

A deep technical dive into scaling laws specifically for T2V models. The authors find that, counter-intuitively, investing compute in model depth (layers) yields better returns than width (parameters) for video tasks, providing a crucial practical guide for efficient architecture design.
