Apple Final Cut Pro 7 - Manual (Page 1531)

Because this is actually one command whose behavior adjusts depending on the type
of clip selected, there is only a single button, called Make/Break Master Clip, to access
this command in the Button List and Keyboard Layout window. To determine the results
of clicking the Make/Break Master Clip button, determine which kind of clip is selected
and use the table above.
Moving Clips Between Projects
For certain workflows, you may need to create multiple projects and move clips between
the projects. In Final Cut Pro, you can move a clip by dragging it from one project tab to
another or by copying and pasting a clip.
When you move or copy a clip from one project (called the source project) to another (the
destination project), Final Cut Pro checks to see if the destination project contains a
matching master clip. There are three possible outcomes:
• Clips do not match: If the destination project doesn’t contain any clips that match the
new clip, the new clip becomes a master clip in the destination project.
• Clips match exactly: If the destination project contains a clip that exactly matches the
new clip, Final Cut Pro adds the new clip and makes it an affiliate of the master that
already exists.
• Clips match but some properties are different: If a clip from the source project matches
a master clip in the destination project but one or more properties conflict, Final Cut Pro
displays the Copy Master Clip dialog and the conflicting properties are highlighted in
red.
For information about resolving property differences between matching clips, see
“Resolving Property Differences Between Matching Clips.”
How Does Final Cut Pro Identify Matching Clips?
Internally, each master clip in a project has a unique number called a universally unique
identifier (UUID). No two clips in a project can have the same UUID. When you drag or
paste a clip from one project to another, the destination project may already contain a
clip with the same UUID as the source project clip. When the source and destination clips
have matching UUIDs, Final Cut Pro detects a match. When both clips’ properties match,
the clips match exactly. When the source and destination clips have one or more
nonmatching properties, you must choose how to resolve the differences.
