title: Swift - Create Custom Capture Session Preset
body: <p>I want to create a custom camera that records square videos. However, all of the capture session presets are not in square format</p>
  
  <p>For example:</p>
  
  <ul>
  <li><p>1920x1080</p></li>
  <li><p>1280x720</p></li>
  <li><p>640x480</p></li>
  </ul>
  
  <p>Is there anyway i can create a custom preset. I still want to have high quality videos but in square format. The closest thing to square format is 640x480, but i still want HD Quality.</p>
  
  <p>Is this possible, if so how? Thank you</p>
