- TLDR:Positive--Direction Matching (PDM), a branch-aware OPD objective that separately constrains the positive prediction and the CFG conditional direction, is introduced to dense-to-sparse video control, where naive guided matching is highly sensitive to inference guidance scales, while branch-aware supervision enables more robust and effective knowledge transfer.

- TLDR中文:将 Positive--Direction Matching (PDM)——一种分支感知的 OPD 目标,分别约束正预测方向与 CFG 条件方向——引入 dense-to-sparse 视频控制;由于朴素的 guided matching 对推理 guidance 尺度极为敏感,分支感知监督可实现更鲁棒、更有效的知识迁移。
