Since it is a one-pass encoding system where it has to choose on the
fly, it is not able to achieve exactly what you ask for.
If you actually want 13500 bitrate, set the max slider to be *less*
than the avg slider, and that will tell the system to switch from VBR
It is on my TODO list, to change that screen to have a separate
check-box for designating CBR instead of VBR.
A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
