Transitions and effects can be very useful tools to stylize your video…. when used in moderation. Going overboard with transitions and effects will distract your viewer and make your video look corny. I mean, how many star wipes do you really want to sit through?
Adding transitions in iMovie is simple. Click on the transitions icon beneath the viewer. It’s the square icon made up of four triangles. You can then drag whichever transition you choose to the space in between any two clips. This will apply the transition.
