-f<format>, --format=<format> - What format to create the video in, default is mpg. For ffmpeg only.
|

-o, --overwrite - Whether to overwrite an existing file, off by default.
|

-v, --version - Outputs the currently installed version of ZoneMinder
|

-c[=filename], --concat[=filename] - When creating videos for multiple events, create a concatenated video as well.
