is this needed for a given monitor definition or do you want it to work 
on any monitor?
if it's for your own monitor only, at a given definition, let say 
1024x768 a combination of vf scale and expand could work:
	-vf scale 1024:-2:0:0:20,expand=0:768:0:384
-vf scale scales the movie to the width of the screen, keeping the 
orginal aspect ratio (-2 for the height)
then vf expand expands the height with black bands to fit the height of 
the screen and places the movie on the middle (position to 384 = 768/2).
and you can put your subtitles in the bottom black band.
nevertheless, because of the windows bars and borders your window will 
not fit on the screen, it will be too big. It will only fit when 
switching to full screen).
furthermore, if you only need a little black space to put your subtitles 
underneath the picture this is enough:
	-vf scale=1024:-2:0:0:20,expand=0:-140:0:70
and then full screen.

was it what you looked for?
