Compressor: Don't export from Final Cut Pro using a QuickCluster
Symptoms
You will not be able to successfully export from Final Cut Pro using Compressor if your computer is set up as a Compressor QuickCluster, or a "Virtual Cluster." If you attempt to send an item from Final Cut Pro to Compressor in such a case, some segments in the job may report "Failed" and processing of the batch will not complete successfully.
Products Affected
Compressor 3
Resolution
You can work around this issue by first exporting a self-contained movie from Final Cut Pro. You can then use a QuickCluster in Compressor to transcode that self-contained movie.
Alternately, you can export from Final Cut Pro directly using Compressor, but use a single-service instance of Compressor instead of a QuickCluster.
Additional Information
A QuickCluster or "Virtual Cluster" is a standalone computer that is configured so its multiple CPU cores can each act as a Qmaster service instance, thereby allowing more data to be processed simultaneously.
For more information about Compressor and Qmaster configuration options, refer to the document titled, Distributed Processing Setup, available under the Help menu in Compressor. Additional information can be found in the Compressor Release Notes.
