ContextMaster: Interactive Multi-Shot Video Creation via Fixed-Budget Sparse Context Routing

A two-stage privileged context distillation framework, which transfers full context behavior from a dense teacher through consistency distillation and then refines deployment rollouts with distribution matching, is proposed, which transfers full context behavior from a dense teacher through consistency distillation.

Temporal Concentration from Rollout Errors: Implicit Preference Optimization for Text-to-Video Diffusion

Concentrated Implicit Preference Optimization (cIPO) is proposed, a post-training framework for video diffusion models that captures inference-time errors without requiring human annotations or external reward models and consistently enhances video authenticity and temporal coherence across multiple datasets.
