Both x265&x264 during cfr encoding should properly hit the average bitrate specified. (assuming you use VBV, normal level restrictions and don't forcefully try to break it,..)
My guess is that you are encoding vfr content and with vfr the average bitrate during playback might differ and my guess is that MediaInfo somehow estimated a max bitrate that !might! occur with vfr content.
-> if you find a proper definition of what MediaInfo reports as nominal bitrate and how it comes up with that value there might be a way to take it into account.

Understood.. But even if we ignore MediaInfo.. I have 2 movies which were encoded using the same profile (2500kbs)..
One is 99mins and ends up at 2.8GB
The other is 91mins and ends up at 1.8GB
I understand that the amount of motion can affect the ultimate size, but not 30% (and these are very similar).. But both of these movies are similar types and one has ended up 1GB smaller, for a movie which is 9 mins shorter.
I just know from experience that 2.8GB for a 90ish minute movie encoded at 2.5kbs is too big. .I wonder if I should just force it to be smaller, by encoding at something like 1800kbs, just to get the final size down?
