title: Is it possible to programmatically create video frame-by-frame in iOS?
body: <p>I want to make an app where users can create funny stick figure animations.</p>
  
  <p>It would be cool if it is possible to export them as video. Can I "draw" video frames frame by frame and render them into a H.264 or other video format?</p>
  
  <p>The length will be between 2 seconds and 5 minutes. I heared a while back that there is a framework to edit video but in my case I really need to create a video from scratch. What are my options?</p>
