Goodbye Drift: Anchored Tree Sampling for Long-Horizon Video-to-Video Generation

ArXi:2605.20476v1 Announce Type: new Long-horizon video generation suffers from two intertwined issues. First, there is drift, where video quality degrades over time. Second, there are continuity issues which manifest as object permanence issues, or improperly rendering transient content (e.g., an object that appears in non-consecutive frames changing color/style).
