ContextMaster targets multi-shot video creation
The paper introduces a unified model for generation, reference conditioning and editing across video shots.
Why it matters
The work addresses a practical bottleneck in AI video workflows: maintaining continuity and usable context across iterative, multi-shot creation. Its fixed-budget context strategy points to more scalable interactive video models.
The key points
- 1.ContextMaster formalizes interactive multi-shot video creation.
- 2.It unifies generation, reference conditioning and editing in one model.
- 3.Sparse context routing keeps context access within a fixed budget.
Researchers introduced ContextMaster, a model framework for interactive multi-shot video creation. The approach unifies text-based generation, reference-conditioned generation and source-footage editing while maintaining shared history across shots. It uses role-aware context representation, reusable clean context states, fixed-budget sparse context routing and ConstraintSink to keep task constraints visible without growing context-read cost at each denoising step.
