title: How to do timecode calculation?
body: <p>I got a question regarding calculating time code delta.<br>
  I read metadata from a movie file containing a timecode formated <code>HH:MM:SS:FF</code></p>
  
  <p>(<code>FF</code> = frame, <code>00-&gt;23</code> for example. So its like <code>00</code> to <code>framerate-1</code>) </p>
  
  <p>So i get some data like <code>15:41:08:02</code> and from another refrence file i get <code>15:41:07:00</code><br>
  Now I have to calculate the timeoffset (like timedelta but just with frames).<br>
  How would i go around doing this?</p>
