I am a begineer in Python. Actually I am encoding video files with different bitrates using ffmpeg CLI. I wanted to ask you that how can I make loops so that I can vary the bitrates in the CLI of ffmpeg??


I want to bulid a loop for the command below where i just want to vary the -vb parameter i.e. 10M. 


ffmpeg.exe -i sample.avi -y -f h264 -vb 10M -r 25 encoded_1000_0-05.h264


I have tried to make simple loops but it doest work:(


Can anyone here help me out?
