Video Understanding Technology Realization and Application Boundaries
CogVLM2 realizes the video understanding function through an innovative key frame extraction technique, and the system supports the processing of 1-minute-long video content by default. This feature performs multimodal characterization of the video: on the one hand, it extracts key visual information through computer vision techniques, and on the other hand, it combines temporal modeling to understand the continuity of the action. Compared to the 2-hour video processing capability supported by Smart Spectrum GLM-4V-Plus, the current implementation of CogVLM2 focuses more on single-shot depth understanding accuracy.
In practical applications, a 1-minute video processing capacity can already meet the needs of typical scenarios such as short video analysis and teaching clip comprehension. The model will intelligently select the most representative key frames to be analyzed to ensure the best video content understanding effect under limited computing resources. Users can directly input video files for analysis through the predict interface, and the system will automatically complete the whole process of key frame extraction to semantic understanding.
