Hi Paul,

You're right.
It's just, I didn't find anything relevant to really adjust the output bit rate.
Perhap's I missed something...somewhere.

Thank's for your help.

Next time specify what you actually tried.

qscale is not for reaching specific bitrate. It solely purpose is to
give you best quality under variable bitrate, whatever that means.
