PreCoG: Preview-Edit for Efficient Video Correction in Generation-Time

PreCoG is an iterative framework that corrects semantic failures in text‑to‑video generation by using low‑cost previews to diagnose issues (PreQA) and then editing cached generation trajectories (PreEdit) under corrective conditions. This approach limits disruption to already correct content and only completes generation for selected candidates, reusing cached trajectories to reduce redundant computation. Experiments show that PreCoG achieves top scores on VBench and T2V‑CompBench, approaches VSR’s VS2 score at 0.56× inference time, and outperforms GENMAC on all quality and alignment metrics at 0.86× inference time.

Memory-V2V: Memory-Augmented Video-to-Video Diffusion for Consistent Multi-Turn Editing

Memory-V2V is a memory‑augmented video‑to‑video diffusion framework designed to improve cross‑turn consistency in multi‑turn video editing. It stores previous outputs in an external memory, retrieves relevant edits, and incorporates them via relevance‑aware tokenization and adaptive compression, allowing scalable conditioning without linear computational growth. Experiments on iterative video novel view synthesis and text‑guided long video editing show that Memory‑V2V enhances consistency while preserving visual quality and outperforming strong baselines with modest overhead.

OmniEdit-Bench: A Comprehensive Benchmark for Instruction-based Video Editing

OmniEdit-Bench introduces a comprehensive benchmark for instruction-based video editing (IVE), addressing limitations of existing datasets by covering spatial, temporal, audio, and reference-based editing tasks and distinguishing explicit from implicit instructions. The evaluation framework assesses editing quality across accuracy, preservation, realism, and consistency, using human judgments and vision-language models, and incorporates an accuracy-aware penalty to ensure instruction fidelity. Experiments reveal that current IVE models perform poorly, highlighting the need for improved methods.

WanPE: Towards Cinematic Prompt Enhancement for Modern Text-to-Video Generation

WanPE is a 397‑B parameter prompt‑enhancement model that learns director‑level cinematic planning from 1.05 M real‑world videos. It generates shot‑level cinematic plans through video‑grounded reverse construction and uses Semantic‑Consistency GRPO (SC‑GRPO) to maintain user intent across shots and time. In evaluations, WanPE improves human preference over raw prompts by up to 50.86 points for 30‑second videos and outperforms commercial offerings for shorter durations.

TetherCache: Stabilizing Autoregressive Long-Form Video Generation with Gated Recall and Trusted Alignment

Autoregressive video diffusion models provide a natural formulation for streaming and variable-length video generation by conditioning newly generated frames on previously generated content. However, extending these models to minute-level generation remains challenging: the limited KV-cache budget prevents the model from retaining the full history, while repeatedly conditioning on self-generated frames induces a context distribution shift that accumulates over time, leading to visual artifacts, quality degradation, and temporal drift.

ReferStream: Interactive Subject Injection for Streaming Video Generation

ReferStream is a new framework for interactive subject injection in streaming video generation that does not require additional training. It constructs reference features using the current scene and injects them via a transient cache, then restores the global cache to preserve existing context. The authors also introduce ReferStream Bench, a benchmark with scheduled reference arrivals and evolving instructions, and show that their method outperforms baselines in text adherence, subject similarity, and count accuracy.
