That will mean quick and dirty encoding, at the cost of a higher bitrate.
-preset slow will make the file significant smaller, at the cost of more 
processing time / cpu use.
(And thus energy use, but if you stream too large files a gazillion times, you 
might want to invest in high quality encoding instead of quick ’n dirty.)
It’s a ‘would you like to be bitten by the cat or by the dog’ situation.
