REEL: Learning to Retrieve, Evaluate, and Evolve Visual Memory for Any Long-Horizon Multi-Shot Video Generation

Memory-based long-video generation aims to combine user control with long-range visual consistency.

Key points

  • Representative multi-shot systems couple memory to generator-specific interfaces or use predefined agent workflows, rather than independently training a memory policy for cross-shot objectives.
  • We introduce REEL, a general-purpose visual-memory planner.
  • To train REEL, we construct two high-quality datasets, REEL-SFT-4k and REEL-RL-1k, covering diverse interaction patterns and prompt types.
  • REEL-Bench tests identity preservation and intended state changes under text-only requests and timed reference-image uploads.
