Researchers have developed MERIT, a novel framework for understanding ultra-long videos that exceed practical processing limits for current multi-modal large language models. MERIT employs a two-stage approach, first constructing a query-agnostic memory with a focus on retrievability and then performing retrieval-based inference. This method utilizes an episodic multi-key representation for precise memory retrieval and a neighbor filtering mechanism for capturing broader semantic context by expanding temporal scope around retrieved segments at inference time. MERIT has demonstrated state-of-the-art performance on benchmarks such as EgoLifeQA, LVBench, and Video-MME (Long). AI
