Exporting video with Video Analytics meta data is very useful in the process of optimization of Video Content Analytics performance. One could configure VA, record particular scene and then replay this scene over and over again using different VA configurations.
Moreover the video could be exported and replayed multiple times with different VA configuration settings.
This article describes the different possibilities - VRM eXpport Wizard and Web Interface of a Bosch Camera. The choice of the tool depends on the way the camera and recording are managed.
Camera that is managed by non Bosch Video Management System (also no VRM recording), or is not recording - Camera Web Interface
VRM recorded video - VRM eXport Wizard
