Researchers have introduced CamChoreo, a new benchmark dataset designed for understanding complex camera motions in videos. This dataset features 4,229 real-world clips with detailed temporal annotations, where nearly half of the segments include multiple simultaneous camera movements. To address the limitations of current multimodal large language models (MLLMs) in recognizing these fine-grained motions, the team developed CamDistill. This method distills geometric knowledge into lightweight tokens, enabling accurate camera motion recognition at inference without requiring a separate 3D foundation model. AI
