=head1 NAME
zmvideo.pl - ZoneMinder Video Creation Script
=head1 SYNOPSIS
zmvideo.pl [ -e <event_id>,--event=<event_id> | --filter_name=<filter name> | --filter_id=<filter id> ]
[--concat=filename]
[--format <format>]
[--rate=<rate>]
[--scale=<scale>]
[--fps=<fps>]
[--size=<size>]
[--overwrite]
=head1 DESCRIPTION
This script is used to create MPEG videos of events for the web pages
or as email attachments.
=head1 OPTIONS
-c[=filename], --concat[=filename] - When creating videos for multiple events, create a concatenated video as well.
- If not specified, filename is taken from filter name.
-e<event_id>, --event=<event_id> - What event to create the video for
--filter_name=<filter name> - The name of a saved filter to generate a video for all events returned by it.
--filter_id=<filter id> - The id of a saved filter to generate a video for all events returned by it.
-f<format>, --format=<format> - What format to create the video in, default is mpg. For ffmpeg only.
-r<rate>, --rate=<rate> - Relative rate, 1 = realtime, 2 = double speed, 0.5 = half speed etc.
-s<scale>, --scale=<scale> - Scale, 1 = normal, 2 = double size, 0.5 = half size etc.
-t<transforms>, --transform=<transforms> - Transform video. Applies -vf option to ffmpeg.
-F<fps>, --fps=<fps> - Absolute frame rate, in frames per second
-S<size>, --size=<size> - Absolute video size, WxH or other specification supported by ffmpeg
-o, --overwrite - Whether to overwrite an existing file, off by default.
-v, --version - Outputs the currently installed version of ZoneMinder
