title: What is usage and purpose of Bitrate in AWS Elastic Transcoder Presets
body: <p>I want to transcode a video using aws elastic transcoder jobs. I have checked video transcoding with <a href="https://console.aws.amazon.com/elastictranscoder/home?region=us-east-1#preset-details:1351620000001-400050" rel="nofollow noreferrer">preset</a> id "1351620000001-400050" for "Smooth 800k" and this preset having max bitrate 688</p>
  
  <p>Is this mean 688 kbps?? 
  And the input video transcoded with in OR equal to 688??</p>
  
  <p>Refer the image,

  <p>If it is, in my case it behaves differently,</p>
  
  <p>An input video bitrate of "10479 kbps", it was transcoded into 5812 kbps.</p>
  
  <p>Is it expected behaviour??</p>
  
  <p>What is the purpose and usage of Bitrate in AWS ealstic transcoder presets?</p>
  
  <p>Kindly provide your inputs.</p>
