The present invention provides a video intelligent analysis system and method based on big data. The system comprises a parsing scheduling module, an analysis queue management module, a task decomposition module, a task encapsulation module, a distribution transmission module, a parsing processor and a video big data system. The method comprises that: according to the input data source and relevant instruction information, a parsed object package is packaged into and sent to the analysis queue management module; the task decomposition module outputs the received video slice to a sub-video package according to a scheduling module instruction; the received sub-video is processed and encapsulated into the task package; the distribution transmission module sends each subtask to each concurrentprocessor in the distributed processor; each concurrent processor runs and processes the received subtask at the same time; combination is carried out; and a processing result is returned to a request unit. According to the technical scheme of the present invention, the mature big data software can be directly used to perform analysis and processing, so that the utilization of video resources andthe use efficiency are greatly improved.
