Object detection models like YOLO excel at real-time, frame-level inference and producing clean bounding box outputs, but they fall short when it comes to understanding video as data. The limitations arise in system design rather than model performance, as frame-level predictions do not naturally support temporal reasoning, nor do they provide a searchable or queryable representation. Additionally, audio, context, and higher-level semantics are often disconnected, highlighting the difference between identifying objects in a frame and understanding the events in a video. The focus needs to shift towards building pipelines that incorporate temporal aggregation, multimodal fusion, and systems that enhance rather than replace models. This approach aims to address the complexities of video analysis, emphasizing the need for both advanced models and robust systems. Understanding these limitations is crucial for developing comprehensive video intelligence solutions.
