40 Part I Media and Project Management
Source Shows the file path of the clip’s media file on disk. For example:
Scratch Disk:Capture Scratch:Dining:Interview Clip.mov
This property is the critical connection between a clip and its
media file. If a media file changes location or name, or if its
modification date changes, the clip will no longer be able to locate
it based on its Source property’s file path, causing the clip to
become offline.
A clip’s Source property may contain a file path (even if the file
cannot be located) or it may be empty (as is the case with a newly
logged clip, or a clip made offline using the Make Offline
command).
You can reveal a clip’s media file by selecting it and choosing
View > Reveal in Finder.
TC Displays which timecode track in the media file is currently being
used to display timecode for the clip in the Browser, Item
Properties window, the timecode fields of the Viewer, and the
timecode overlays in the Viewer and Canvas. For example, if a
media file has three timecode tracks, the choices would be:
 Source
 Aux 1
 Aux 2
“Source” merely indicates the primary timecode track of the media
file, and is almost always the timecode from the original source
tapes. Since most media files have only one timecode track,
“Source” is often the other choice. However, if you have added an
auxiliary timecode track to a media file (for example, with the
Modify Timecode command), you can choose to view the timecode
values stored in this track instead.
You can adjust the TC value in the Browser, Item Properties
window, or by control-clicking in the Timecode Duration or Current
Timecode field.
Thumbnail Displays a small, representative frame from the clip’s media file. By
default, the thumbnail is the first frame of the clip, but you can
drag to “scrub” through the clip to choose a more appropriate
representative frame, known as a poster frame.
For more information, see Volume I, Chapter 5, “Browser Basics.”
Tracks The total number of video and audio tracks in a clip or sequence.
Type Type of clip: Clip, subclip, multiclip, still.
Also: Sequence, bin, or effect.
Vid Rate Shows the frame rate (timebase) in frames per second (fps). For
clips, this property is the frame rate of the media file on disk. For
sequences, the frame rate is set in the sequence’s editing timebase
field. If a sequence contains clips, the sequence’s frame rate
(editing timebase) cannot be changed (unless all clips are first
removed).
