Microsoft Azure AI has launched MM-Vid, integrating GPT-4V with dedicated tools to interpret long videos and provide a better experience for the visually impaired. MM-Vid comprehensively understands real-world videos through key modules such as multimodal understanding and coherent narration. Experiments show exceptional performance in tasks like question answering and character recognition, with the capability to continually receive streaming video frame inputs. This innovation is expected to drive the development of large multimodal models and provide more robust solutions for video understanding. The successful integration of GPT-4V addresses the needs of conventional video understanding and the visually impaired.
