title: iPhone - how can I record 8 hour video for sleep studies?
body: <p>I would like to try recording sleep with an iPhone, connected to a power source overnight. However, I'm not sure if the default camera is capable of recording videos that long. A colleague suggested using a video codec with very few key frames, just saving the changes between frames. </p>
  
  <p>My questions are twofold - <strong>are there any open source projects that already do long(3+ hours) video recording on iPhone.</strong> How would I extract the file from the iPhone if it is 3 Gb or so in size?</p>
