How can I apply transitions to my project?

To apply transitions to the clips in your project, you can first browse the wide variety of Effects available in the app. You can see them all and try them out by tapping on the star icon from the menu at the bottom of the screen.

Effects include different types of transitions. If you like a specific effect but you'd rather turn off the transition associated with it, you can do so by tapping on the three-dots icon visible on the effect preview as soon as you select it: a new section will show up and you'll be able to customize each component of that effect.
