Understanding the Adobe After Effects Timeline

The timeline in Adobe After Effects is where you will spend most of your time while working on your animations or video projects. It is where you arrange and manage all the layers of your projects, apply effects, and basically control the frames and timing of your animation.

How to Extend the Timeline

To extend your timeline, you need to increase the ‘Composition Duration.’ Here’s how you can do it:

  1. First, navigate to the ‘Composition’ menu, and then select ‘Composition Settings.’
  2. In the Composition Settings dialog box, you will find the ‘Duration’ option under the ‘Basic’ tab.
  3. Change the duration to the desired length. Remember, the format for entering the duration is: Hours:Minutes:Seconds:Frames.
  4. Click on the ‘OK’ button to apply the changes.

Your timeline should now extend to the new duration you’ve set.


Extending the timeline in Adobe After Effects is a simple and straightforward process once you know where to look. With just a few clicks, you can have all the time you need to perfect your animations or videos. We hope this guide was helpful in solving your timeline issues. Keep animating, and stay creative!
