title: How do you change the MIME on Amazon S3?
body: <p>I am trying to change a mp4 video file's MIME that is stored on Amazon S3.</p>
  
  <p>I tried searching under the properties listing when you right click and then the meta-data drop down. But there is no option for that there.</p>
  
  <p>How do you I do that?</p>
