maxAverageBitrate property
Use this setting only when Rate control mode is QVBR and Quality tuning level is Multi-pass HQ. For Max average bitrate values suited to the complexity of your input video, the service limits the average bitrate of the video part of this output to the value that you choose. That is, the total size of the video element is less than or equal to the value you set multiplied by the number of seconds of encoded output.
