I'm trying to encode my movies into WebM:

ffmpeg -i input.MOV -codec:v libvpx -quality good -cpu-used 0 -b:v 10k
-qmin 10 -qmax 42 -maxrate 10k -bufsize 20k -threads 8 -vf scale=-1:1080
-codec:a libvorbis -b:a 192k
output.webm

I want to encode at a couple of different bit rates (video and audio combined):

  • 2192 kbps
  • 1692 kbps
  • 1000 kbps

The problem is that no matter which bit rates I enter, I always get a file with a bit rate higher than 1900 kbps. (1914 kbps with the code example above.)

What am I doing wrong?
