Adding clips overview
You build a movie project by adding clips to the Timeline in a chronological arrangement. To suit your particular editing style or need, you can choose from a wide variety of tools and techniques for adding clips. You can change the arrangement of the clips in the Timeline at any time.
In Final Cut Pro, you can edit your projects without worrying about maintaining clip connection or synchronization. For example, when you drag a clip into the Timeline, Final Cut Pro automatically rearranges the Timeline to fit each new clip without disturbing your existing work. This is true for all kinds of clips: video, audio, titles, generators, still images, and so on.
You can use clips from multiple events in a single project. You can also add clips from the Final Cut Pro media browsers and from the Finder. Deleting clips from the Timeline does not affect clips or files in the Browser, the media browsers, or the Finder.
In the Browser, an orange line along the bottom of an event clip indicates the clip is being used in the current project (open in the Timeline). To turn this view on or off, choose View > Show Used Media Ranges.
