script-fu is something I do not use, so I will give my example
implementation in a form that you could call from the PyGimp console.

def autocrop_many (pattern):
  import glob
  filenames = glob.glob (pattern)
  for filename in filenames:
    #the following is a direct translation of your script-fu.
    image = pdb.gimp_file_load (filename, filename)
    drawable = image.active_layer
    pdb.plug_in_autocrop (image, drawable)
    pdb.gimp_file_save (image, drawable, filename, filename)
    pdb.gimp_image_delete (image) # this line may not be needed

If you paste the above into a PyGimp console, then call it like
autocrop_many ('/path/to/files/movie*')
it should do what you want.

If you don't have python support installed, I can only help by
pointing out basic errors in your code; I know little of script-fu

* plug_in_autocrop accepts an image as it's first parameter, but you
provided a filename.
(you also are trying to call 'plug_in_autocrop', whereas the function
is named 'plug-in-autocrop'. -/_ substitution is only used if you're
coding your plugin in Python.)
 I think you meant to call zac-autocrop here, anyway.

^^
the above line has the _ / - mistake I pointed out earlier in this email.

You defined zac-autocrop correctly, but you haven't registered it with GIMP.
See this link for an example.

Hope that helps!
