How to export video including Video Analytics meta data?

[#1]

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.

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 - Configuration Manager. Configuration Manager is now the best tool for configuring VCA/IVA and some of the other items that required ActiveX.
• VRM recorded video - VRM eXport Wizard
• Camera that is managed by Bosch Video Management System -  VRM eXport Wizard
  

Note: Forensic search makes possible to search the meta data of the recorded video and select the relevant export stamp. Forensic search is part of BVMS OC and BVMS Viewer
