IMovie

iMovie is a free video editing software created by Apple.

Bad Qualities

 * 1) When a file is imported into the app, it duplicates itself and wastes space.

 * 3) There are only two layers of video, but infinite layers of audio.
 * 4) It may crash sometimes.

Good Qualities

 * 1) You can export videos in 4K.
 * 2) There is the ability to record your own voice.
 * 3) There are audio tracks that are worth the app.
