-It accepts the syntax: @var{movie_name}[:@var{options}] where
-@var{movie_name} is the name of the resource to read (not necessarily
-a file but also a device or a stream accessed through some protocol),

-The description of the accepted options follows.
+This filter accepts the following options:
