A clip is considered offline when:
 The clip’s Source property is incorrect (when there is no media file at the file path in the
Source property). This happens when a media file is modified, moved, or deleted, the
modification date of the media file is changed, or the scratch disk becomes unavailable.
 The clip’s Source property is empty. You can intentionally make clips offline by choosing
Modify > Make Offline, or you can create a new offline clip by choosing File > New >
Offline Clip. Final Cut Pro doesn’t warn you about offline clips whose Source property
is empty, because there is no media file path to check.
Sequences as Clips
Sequences are special containers for clips arranged in chronological order. However, in
some cases, sequences can also be treated as clips. For example, you can check the
Item Properties of a sequence just as you can for a clip, and information about the
sequence shows up in the Item Property columns in the Browser. You can also edit
sequences into other sequences. This is called nesting a sequence. For more
information, see “
Viewing and Changing the Properties of a Clip
Each item in the Browser, such as a clip, has a set of properties. You can view all the
properties of a clip in the Item Properties window as well as in columns in the Browser.
Some properties can be changed directly in the columns of the Browser; others can be
changed in the Item Properties window.
Certain properties, such as frame size or video rate, are determined by a clip’s media file
and cannot be changed without using the Media Manager.
For a detailed table that describes all clip properties, see Volume IV, Chapter 3,
“Elements of a Final Cut Pro Project.”
Changing Clip Properties in the Browser
Being able to change clip properties directly in the Browser columns is very convenient.
You don’t need to open any additional dialogs or windows unless you have a specific
reason for doing so. For example, you can clear the In or Out point of a clip, or enter a
comment in one of the Master Comment columns.
It’s just as easy to change the properties for multiple clips as it is for a single clip,
although some clip properties can only be changed one clip at a time. If you want to
quickly change many properties of a single clip, it may be easier to use the Item
Properties window.
