title: Compressing size of mp4 file
body: <p>I'm trying to compress an mp4 file to reduce the file size. I am using a Debian box.</p>
  
  <p>The file is around 701 MB. First, I tried bzip2, which compressed it down to like 700MB, then I tried lrzip with zpaq, took like 5 mins to compress, and only brought it down to like 695 MB... Am I doing something wrong?</p>
