How to change the duration of elements?

On the scene timeline, you'll be able to see all the elements on the scene and project timeline with their current duration. 

To change the duration of a certain element:

Step 1: Select the element.

Step 2: Drag the element handles in or out to adjust their entry and exit times.

Element durations determine when and how long we would like to have it on the video and also helps us have elements come one after another.
