By default, all scenes are set for 10 seconds. However, you can increase or decrease the duration of the scene at your convenience.
There are 2 ways to adjust the length of the scene.
From Scene Timeline:
You can edit the scene length from the Scene Timeline. In the bottom right of the screen, there are ‘+’ and ‘-’ icons.
The scene length will increase exactly by 1 second when you click on the ‘+’ icon.
Similarly, the length will decrease exactly by 1 second when you click on the ‘-’ icon.
2. From Overall Timeline:
If you want to trim your video to a very specific timestamp, then you can do it from the Overall Timeline.
Drag the right end of the scene until you achieve the desired length.
