probably stupid Avisynth filter question

[ecc]

I was looking at some examples of Avisynth scripts and it looks like I might have left something out in the encodes I have been doing, so here's the question:

when you load a plugin [i.e. loadplugin()], does that apply it to the file when you open it up in an encoder or do you also have to list the plugin as one of the commands below the source?

for instance:
loadplugin("decomb.dll)
mpeg2source("...")
crop(...)
resize(...)
decomb()

[jagabo]

Loadplugin() makes AVISynth aware of the plugin and its function(s). It does not use the function(s) unless invoked later in the script.

And Decomb isn't used as Decomb, but as, for example:

Telecide(Guide=1).Decimate()

Decomb is the name of the filter suite, which includes Telecide, Decimate, and FieldDeinterlace.
