Command Line Interface
ClearView File Importer provides the ability for the video to be decoded using a Command Line input. CVI.exe can
be invoked from the command line for batch processing. Multiple instances of CVI.exe can run in parallel.
All settings, available in Graphical User Interface mode are also configurable with specific input commands using
the Command Line Interface.
Command Line supports batch video maintenance of the source files located both on the local workstation and on
a network location.
