Use distributed processing
Transcode batches using other computers
Transcoding a series of large les on one desktop computer can be processor-intensive and time-
consuming. Distributed processing decreases the time it takes to transcode a batch by distributing
the work among two or more computers. After you set up a distributed processing system,
Compressor sends portions of your batch to each of the available computers in your group of
shared computers. When the transcoding is complete, the output les appear in the location you
specied when setting up the batch.
The simplest distributed processing system uses two computers. A more complex system can
include many computers.
To set up distributed processing, you turn on access to your computer and then create a set of
shared computers. If you can’t nd a computer on your network, you can manually add it to the
computer list.
Important: Before you begin, verify that all the systems that will be used for distributed
processing have the same version of Compressor installed.
Make your computer available to other computers on your network
1 Choose Compressor > Preferences (or press Command-Comma).
2 Select My Computer.
3 If necessary, turn on “Allow other computers to process batches on my computer.”
4 To control access to your computer, select the Require Password checkbox and enter a password
in the text eld.
The password will be required to use your computer for transcoding.
Create a group of shared computers
You can create a group of shared computers to use to transcode your batches.
1 Choose Compressor > Preferences (or press Command-Comma).
2 Select Shared Computers.
3 At the bottom of the list of shared computers (on the left), click the Add button .
A new “Untitled” group is added to the list.
4 Double-click the “Untitled” group to select it, and type a new name for the group.
5 In the list of available computers (on the right), select the checkbox next to each computer that
you want to add to the set.
If a computer doesn’t appear in your list of computers, you can add it to the list using the
computer’s IP address (described in the next task).
If you’re using an Xsan, be sure to turn automatic le sharing o. For more information, see
Manually congure le sharing on page 103.
If you need to remove a group of shared computers, select the group and click the Remove
button .
