title: How can I add a watermark in a captured video on iOS
body: <p>I was wondering if anybody can tell me how I can achieve this. If been thinking of a couple of solutions:</p>
  
  <ol>
  <li><p>Create individual images from the captured video and later merge them per image and after that create a new AVAsset... Sounds a bit complicated don't you think?</p></li>
  <li><p>Merge 2 videos, one is transparent (the one holding the watermark) and the other is the asset captured with the camera.</p></li>
  </ol>
