title: How to get the Start Timecode (SMPTE) of a Quicktime-Movie in Objective-C in 64-bit?
body: <p>I've been pulling my hair out over this.</p>
  
  <p>I've found a few things here, but nothing actually seems to work.  And the documentation is really limited.</p>
  
  <p>What I'm trying to figure out here is how to get the start time code of a Quicktime movie in Objective-C from the timecode track, and getting a human-readable output from that.</p>
  
  <p>I've found this:
  <a href="https://stackoverflow.com/questions/7310299/smpte-timecode-from-quick-time">SMPTE TimeCode from Quick Time</a></p>
  
  <p>It works perfectly in 32-bit mode.  But it doesn't work in 64-bit mode because of the Quicktime API.  The software I need to incorporate it into already has been and must continue to run 64-bit.  </p>
  
  <p>I'm losing my mind here. Anyone out there know about these APIs?</p>
  
  <p>Ultimately, the goal here is to figure out the start timecode of the Quicktime because its needed to set the OFFSET in FCP-X XML files.  Without it, the video files are brought in without audio (or, really, its just slipped a lot).  </p>
