Nice, I've added it to our projects page.

You are mixing up options, suboptions/parameters and filters.

  -vf scale_w=width,scale_h=height,sws=1

would build up a filter chain, calling first the "scale_w" filter with
"width" as parameter, then the "scale_h" filter with height as
parameter and finally the sws filter with "1" as parameter.  Thus

  -vf crop_w=width,crop_h=height,crop_x=x,crop_y=y

would call four filters with one argument, while

  -vf crop=width:height:x:y

calls one filter with four arguments.

Hope this clears up your confusion a bit.
