Another tool at your disposal for organizing media is the use of keywords. You can use two types of keywords when working in Final Cut Pro X:
• Analysis keywords. Final Cut Pro X can automatically generate keywords when you analyze clips for common problems. This can be done on import or after the fact when you select clips in an event and choose Modify > Analyze and Fix.
• Manually added keywords. You can also review clips and choose to add keywords of your own design. This is a great way to get organized based on repeating themes or logical groupings.
