Dear Andrea Ambrosioni
Don't expect your compressed frame sizes to be exactly
the same as you set/expect. I have my experiences with 
only TM5, which will generate some statistics from the
 previous frame!! Hence, be happy if the size is +/- 10%
of the target size and gets adjusted(in TM5) in the 
following frames!!!
With Love
