The resulting file size is approximately video+audio bitrate * time.
So with your 25megabyte file, 500000+56000 bits per second,
the file is probably somewhere around 377 seconds long.
For 18megabyte size, you get a total bitrate of 
(25*1024*1024*8) / 377 = 400517 bits per second. Or roughly
400kbit/s. By dropping vbitrate to 344 (400-56), you might
end up closer to the original filesize..
