Apologies. I should have tried it out first. You are correct. Even specifying 
r:v and -b:v failed.-------- Original message --------From: jmkhoo1

and bitrate 
If you mean a constant frame rate, use -r:v 25. If you actually mean bitrate, 
use -b:v and -b:a. I think you might want to look at the x264 switches to make 
sure that it is encoded and a constant bit rate, though I am fairly sure 
specifying a bit rate will do it.-------- Original message --------From: akash

bitrate 
hello everyone

i have file with CBR and when i am converting it to other format by using
following command i am getting VBR both video and audio

ffmpeg -i input.mp4 -y -r 25 -c:v libx264 -look_ahead 0 -preset veryfast
-b:v 25M -c:a aac ouput.MTS
