Prompt-Adapter Context Routing for Parameter-Efficient Multi-Shot Long Video Extrapolation

arXiv:2607. 06481v1 Announce Type: cross Abstract: We present PACR-Video, a parameter-efficient framework for multi-shot long video extrapolation that preserves recurring entities, scene structure, visual style, and causal progression without full generator fine-tuning.

Making MLLM Latents Matter: Factor-Aware Predictive Learning for Cinematic Video Generation

The paper introduces Factor-Aware Predictive Learning (FAPL) to improve cinematic video generation by effectively leveraging multimodal large language model (MLLM) latents. FAPL trains a Video Diffusion Transformer (DiT) in three stages: grounding the DiT with frozen MLLM latents, enforcing factor-aware control through factor-span replacement, and optimizing temporal inference with limited-input representations while preserving full-observation reconstruction. Experiments show that FAPL outperforms baselines on sparse-to-video, factor-aware editing, and multi-shot generation tasks, demonstrating enhanced MLLM feature use, temporal control, and factor coordination.
