Compressor begins transcoding the Final Cut Pro project and then closes.
Note: Final Cut Pro needs to remain open throughout this process, because much of the
transcoding preparation of the frames occurs within Final Cut Pro rather than within
Compressor.
See Exporting from Final Cut Pro and Distributed Processing for information on how this
process works if you are using distributed processing.
Resubmitting a Final Cut Pro Project
You can use the History window to resubmit a Final Cut Pro project, the same way as you
resubmit any other batch. Compressor recognizes that this particular batch originated
from Final Cut Pro, so when you drag the batch from the History window to the Batch
window, it automatically opens Final Cut Pro.
See Resubmitting a Batch for details about the steps in this process.
Exporting from Final Cut Pro and Distributed Processing
Compressor and Apple Qmaster can distribute video and audio compression tasks over
multiple computers connected to a network.
Note: This Compressor distributed processing feature is limited to computers that have
Final Cut Studio installed.
There are two methods you can use to avoid exporting self-contained media files from
Final Cut Pro for Compressor distributed processing:
• Export a sequence directly from Final Cut Pro to Compressor and then submit that job
to a cluster in an Apple Qmaster distributed processing network. In this workflow,
Final Cut Pro opens on each processing node in that cluster to complete the job.
• Export the Final Cut Pro sequence as a QuickTime reference movie and then submit
the resulting movie to the cluster for processing. Because this method does not involve
Final Cut Pro, you are free to use Final Cut Pro while the batch is being processed in
the background. 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. Below are two sets of instructions
for submitting reference movies: one with automatic file transfer and one with
preparatory steps for maximizing performance.
