Researchers are developing new methods to improve the efficiency and accuracy of multimodal large language models (MLLMs) when processing long videos. VideoMM proposes an adaptive approach that separates semantic filtering from detailed reasoning, using a cost-effective proxy for initial selection before projecting relevant regions to high-fidelity tokens. CodecSight leverages video codec signals to guide inference, reducing computation and improving streaming capabilities without requiring model-specific training. Video-HolmesV2 introduces a benchmark and framework that emphasizes deep audio-visual coupling and requires models to justify answers with precise spatio-temporal evidence, addressing the limitations of visually-centric evaluations and inefficient context processing.
