Moving Clips Between Projects
For certain workflows, you may need to create multiple projects and move clips
between the projects. In Final Cut Express, you can move a clip by dragging it from one
project tab to another or by copying and pasting the clip.
When you move or copy a clip from one project (called the source project) to another
(the destination project), Final Cut Express 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 Express adds the new clip and makes it an affiliate of the master
clip 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 Express displays the Copy Master Clip dialog and the conflicting properties
are highlighted in red.
How Does Final Cut Express 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 Express 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.
