Oh, yeah, this is especially important for offline audio clips, which have NO VISUAL INDICATION in the timeline that they are missing.
If there are offline clips in the timeline Premiere will tell you before it opens the Export Settings dialog box for export.
It does not tell you were these file are in the timeline.
Offline clips and placeholders are colored red in the timeline.
However you can type in Offline in the search box in the project panel. That will give you all the offline clips.
Off line clips used in the timeline have a yellow icon in the lower right hand side, click on this icon and it will give you a reference to that clip.
Click on this text and the playhead will jump to that particular clip.
In Premiere Pro CS6, in Icon View, you can see which clips are used or not, and where they are located in a sequence.
- To view if the clip has been used in a sequence, hover over the filmstrip icon with the mouse and view the tool tip. The indicator also shows how many times the clip is used in the sequence.
- To locate the clip in a sequence, click the filmstrip icon and choose the sequence and sequence location (in timecode) from the context menu. The playhead will jump to the clip in the proper sequence.
