Command Syntax Description
Filter
Filter("name", source,
dest, frame,
duration, fps,
["parmName",
parmValue, ...])
This calls another script, which
must be a filter. It passes one
source and one destination
image buffer, as well as values
corresponding to the frame
where the filter is to begin, the
frames per second for the video
where the frame is found, and
the duration of the filter effect.
You can also set the inputs for
the filter using the parameters
in square brackets. These
should correspond to the
variable names declared to hold
the inputs in the filter script
being called.
