title: iOS AVFoundation - Show a time display over a video and export
body: <p>I want to show a display overlay over a video and export that video including this display. I had a look into the AVFoundation Framework, AVCompositions, AVAssets etc. but I still do not have an idea to achieve this. There is a class called AVSynchronizedLayer which lets you animate things synchrounous to the video, but I do not want to animate, I jsut want to overlay the time display into every single frame of the video. Any advice?</p>
  
  <p>Regards</p>
