====== Extended mode ======

The extended mode adds a second contact sheet after the default contact sheet composed of smaller captures.

A suggested usage of this mode is using the main contact sheet as a //quality preview// (showing the image quality) and the extended contact sheet as a content preview (showing what's in the video).

The extended mode is enabled by the ''-e'' (''%%--%%extended'') option. It has an optional argument ((Note that due to technical limitations, when using the short option form (''-e'') coupled with an extended factor no spaces are allowed in-between, i.e. ''-e8'' is ok, while ''-e 8'' is incorrect)), the //extended factor//, which by default is 4 (so ''-e'' and ''-e4'' are equivalent).


Captures in the extended contact sheet will be 1/4 the size of normal captures (half width and half height).


The //extended factor// is used to determine the number of captures in the extended sheet: The resulting number will be the number of main captures times the extended factor, rounded to the next even number. Confusing I know :-P

== Examples ==

  * ''$ vcs -n2 -e'': 2 captures, 8 extended captures (2x4)
  * ''$ vcs -n1 -e8'': 1 capture, 8 extended captures (1x8)
  * ''$ vcs -n1 -e9'': 1 capture, 10 extended captures (1x9=9, next even number: 10)
