MemDreamer: Decoupling Perception and Reasoning for Long Video Understanding via Hierarchical Graph Memory and Agentic Retrieval Mechanism

Researchers introduce MemDreamer, a framework that enables Vision-Language Models to process hours-long videos by decoupling perception from reasoning through hierarchical graph memory and agentic retrieval. The approach achieves state-of-the-art results while reducing computational context requirements to 2% of full video ingestion, establishing a new paradigm for long-form multimodal understanding.

M$^3$Eval: Multi-Modal Memory Evaluation through Cognitively-Grounded Video Tasks

Researchers introduce M³Eval, the first comprehensive benchmark for evaluating memory capabilities in multi-modal AI models processing long-form video. Testing across multiple models reveals significant weaknesses in maintaining disentangled representations, handling temporal information, and symbolic memory—highlighting memory as a critical yet understudied dimension of AI development.

HPP: Hierarchical Programmatic Probing for Long Video Understanding by Decoupling Perception and Reasoning

Researchers introduce Hierarchical Programmatic Probing (HPP), a framework that separates visual perception from temporal reasoning in long video understanding by enabling coding-capable language models to iteratively probe videos through programmatic exploration. The approach decouples perception and reasoning tasks that traditional vision-language models attempt to handle simultaneously, demonstrating significant improvements across multiple long-video benchmarks including LongVideoBench, EgoSchema, and VideoMME.

Natural-Language Temporal Grounding in Hour-Long Videos is a Search Problem: A Benchmark and Empirical Decomposition

Researchers introduce ExtremeWhenBench, a benchmark for temporal grounding in hour-long videos using natural language queries. The study reveals that video-language models fail dramatically on long-form content because search—not recognition—is the bottleneck, with a hybrid retrieve-then-ground approach recovering 6.7x performance over monolithic models.

LoCoT2V-Bench: Benchmarking Long-Form and Complex Text-to-Video Generation

Researchers introduce LoCoT2V-Bench, a new benchmark for evaluating long-form video generation from complex text prompts, along with LoCoT2V-Eval, a multi-dimensional evaluation framework. Testing 17 models reveals that while perceptual quality is strong, fine-grained text alignment and character consistency remain major technical challenges in the field.
