up menu.
It’s recommended that you first enable all the additional instances,
transcode several test batches, then, if performance is slow,
decrease the number of instances to use fewer of your
computer’s resources. You can use the Activity Monitor
application in OS X to determine the percentage of CPU
resources Compressor is using.
Note: If the computer has a hardware encoder, and if you enable
multiple instances of Compressor, the time it takes to process a
batch can potentially increase, because the hardware encoder
can only be used with single-pass, nonsegmented jobs. If you find
that processing time has increased significantly, turn off additional
Compressor instances by deselecting the “Enable additional
Compressor instances” checkbox.
Transcode Final Cut Pro and
Motion projects using Compressor
If you have Final Cut Pro X 10.2 or later, or Motion 5.2 or later,
installed on the same computer as Compressor 4.2 or later, you
can send sequences or clips from Final Cut Pro or Motion directly
to Compressor for transcoding.
