Nominal Bitrate vs Bitrate?

I will of course share more details... I just wanted to see if you had a quick answer or could explain what i am seeing before I start investigating myself

It all got a bit more complicated now..

Using my 2500kbs Profile I generated this:

Duration                                : 1h 39mn
Bit rate                                : 3 364 Kbps
Nominal bit rate                        : 2 500 Kbps

So last night, I simply changed the bitrate to 1800kbs, nothing else... And this is what was generated:

Duration                                : 1h 39mn
Bit rate                                : 1 800 Kbps


For some reason, when encoding this movie at 2500kbs, it ends up too big and has a higer bitrate than I wanted.. But if i lower it, it comes out a I would expect (although the bitrate is now far too low for a movie of this type).

So I now need to do some more testing to see if I can work out why this is happening.
