iMovie

Organize media and events in iMovie on Mac
If you choose to import video footage into your library, iMovie automatically places the clips into events, based on the date and time the video footage was recorded. Events are like folders that contain your clips. Despite their initial time-based grouping, you can use events to group clips any way you like.
When you select an event in the Libraries list, the clips it contains appear in the browser.
If the Libraries list isn’t shown, click the Libraries List button at the top of the browser.
