Summary
Well done – this summary marks the end of our creative process of just using iMovie. First, we looked at the simplest and most versatile form of an overlay: the cutaway. Cutaways allow you to show different clips such as reaction shots and B-rolls. They can also hide jump cuts you made to make the video more concise. Changing opacity on cutaways allows you to create a double-exposure effect, and can speed up the process of multi-camera editing. Other overlay effects we looked at include split-screen effects and chroma keying, which allows us to remove parts of the frame based on color.
PiP effects allow you to show different clips simultaneously with a lot more freedom than split-screen edits. PiP effects are also the only type of overlay you can animate with keyframes in iMovie. Creating multiple keyframes along the timeline will make an overlay follow an animation path. You can also animate audio levels with keyframes, allowing you to fade volumes up and down smoothly...
