you use framestep=2 when you have progressive/interlaced 59.940fps content and 
want to bring it down to 29.970fps. Though from my experience, depending on 
the content, filmdint will do a better job at bringing it down to 29.970 (it 
can also bring it down to 23.976fps if you combine it with framestep - I used 
filmdint as very simple fps converter, even though it wasn't written for that 
originally)

use a deinterlacer, don't use framestep=2 on 30fps files unless you want 15fps 
output
