Thumbnail Cache Settings
The thumbnail cache stores the clip thumbnails displayed in the Timeline and the
Browser. When you choose to display thumbnails, the thumbnail cache improves the
responsiveness of the Timeline and Browser. There are two settings you can modify:
 Disk
 RAM
Enter numbers in these fields to specify the sizes of the thumbnail caches. You may
want to have large thumbnail caches if you’re working with a large number of clips and
want to display thumbnails or if you are using the Browser’s large icon view.
If you often scrub thumbnails in the Browser’s large icon view, you can optimize their
playback quality by increasing the thumbnail RAM cache. To set a location for the
thumbnail cache, see “
Note: The thumbnail RAM cache uses part of the RAM available to other parts of
Final Cut Express HD, so it shouldn’t be made too large.
Playback Control Tab
Playback Control settings affect all sequences and projects currently open. These settings
also appear in the Real-Time Effects pop-up menu in the Timeline. Using these settings,
you can balance visual playback quality and maximize the available effects that can be
played back in real time. For more information, see “
