Apple Final Cut Express HD - Manual (Page 934)

934 Part XI Project Management and Settings
A clip connects to a media file via the clip’s Source property, which contains the
location of the media file as a file path. If a clip cannot locate its media file, the media
file is considered offline, and the clip is called an offline clip. An offline clip has a red
slash through its icon in the Browser:
Each time you move from Final Cut Express HD to another application and then back
again, Final Cut Express HD checks that the modification date of each clip’s media file has
not changed, and that they are in the expected file path. If a media file has been
modified, Final Cut Express HD warns you that the media file has gone offline, and asks if
you’d like to reconnect the clip. You can choose to do this immediately, or you can do it
later. If you don’t successfully reconnect clips to their media files, the clips remain offline.
How the Connection Between Clips and Media Files
Can Be Broken
There are several reasons the connection between the clips in your project and your
media files on disk can break, causing the corresponding clips in your project to go offline:
 You modified your media files in any way that changes the modification date in
the Finder.
 You moved your media files to another folder.
 You renamed your media files.
 You deleted your media files on disk. In this case, you have no option but to
recapture the media files.
When a clip in your project goes offline, any sequence render files associated with that
clip also go offline, and the Offline Files dialog appears (see “
When
Final Cut Express HD Reconnects Your Clips ” on page 942).
When you play back offline clips, a Media Offline message is displayed until these clips
are either reconnected or recaptured.
These are offline clips.
