Apple Compressor 3 - Manual (Page 356)

6 On each computer in the intended cluster, mount the hard disk (Media1) where the media
files and QuickTime reference movie are located (in the Finder sidebar, click Network,
navigate to the computer that contains the Media1 disk, click Connect, and select Media1).
7 In Compressor preferences, specify cluster options settings:
a Choose Compressor > Preferences, or press Command-Comma (,). The Preferences
window appears.
b Choose “Never Copy Source to Cluster” from the Cluster Options pop-up menu.
8 Import the QuickTime reference movie into Compressor. (Drag it from the desktop to the
Compressor Batch window.)
9 Double-click the file in the Batch window and play it in the Preview window to verify the
integrity of the clip.
10 In the Batch window, assign settings and destinations to the selected file as necessary.
11 Choose the intended cluster from the Cluster pop-up menu in the lower-left corner of
the Batch window.
12 Click Submit.
QuickTime Reference Movies
If you submit a reference movie for distributed processing, the Apple Qmaster distributed
processing system will automatically copy the appropriate media files to the processing
cluster. For the best performance, you can avoid this file transfer step by making sure
that the media files specified in the reference movie are available to each node of the
Apple Qmaster cluster. For more information, see the Distributed Processing Setup Guide,
available in Compressor Help, and
Exporting from Final Cut Pro and Distributed Processing .
Cluster Settings for Extended Transcoding Sessions
If you are using Compressor 2 or later for distributed processing, and you anticipate a
transcoding session that will last up to seven days or longer, you must make an adjustment
in the Advanced section of the Apple Qmaster preferences pane. By default, temporary
process files may remain on a cluster’s scratch location for seven days before they are
automatically deleted. You can increase this value (the number of days) in the
Apple Qmaster pane of System Preferences.
Cleaning Up Cluster Storage
If you are using cluster storage and an error occurs, partial files may be left on the
designated cluster storage location. Check the designated cluster storage location to
make sure no partial media files are left there. If you find partial media files, delete them
and submit the job again.
