precision rate control

[yup]

Hi folk!
I encoding small files (music clib) for mobile phone 3-5 minutes duration. During encoding I always get smaller file size or smaller bitrate. Please advise method for rate control.
With kind regards yup.

Xvid for mobile phone ? what phone exactly ?

doesnt most phone use .mp4

um .. u cant set the bitrate when encoding .. like the 1st pass and 2nd pass bitrate .. u can set that to which ever bitrate u want

Sony Ericsson K750i. I encode use simple level 2 MPEG-4, resolution 176x144 bitrate 128kb/s. Audio support AAC.
yup.

This makes no sense at all. If "u cant set the bitrate when encoding," when do you set the bitrate? If "u can set that to whichever bitrate u want," when do you set that? After the encoding is done?

encoding short sequences xvid struggles to reach a certain bitrate accurately.
I am sure somone here can recommend some settings for making the rate control more stringent and thus hit the bitrate you have specified
