title: How can I display lots of subtitles at arbitrary positions in a video using ffmpeg?
body: <p>I am trying to write subtitles and display them at lots of positions throughout a video at arbitrary positions. I have a long list of times and positions to display the text in the video, but I don't know how to encode these times and positions into the subtitles file. A lot of the examples on the web only show how to display a single subtitle, or don't explain the syntax of the subtitles files.</p>
  <p>I couldn't find a simple answer to how to do this, so I had to put together a lot of methods, and I'm going to answer my own question.</p>
