title: Increasing The Duration Of A Composition In After Effects
body: <p>I want to use a stock composition I downloaded. It is of falling leaves and was built in After Effects using Particular. Find it <a href="http://www.motion-graphics-exchange.com/ufiles/4711/4bdd8e8577f5d/LeavesParticular.zip" rel="nofollow">here</a>!</p>
  
  <p>I need to increase the time of the composition to match a musical number I am using as well (00:05:12:15). I have done the whole right-click on the composition and increase the duration value, but it is still playing for it's default length of time.</p>
  
  <p>The final goal is to use the composition, with a different background, along with the aforementioned musical number for a menu in an Encore project. Thanks!</p>
