26 Chapter 2 The Basic Transcoding Workflow
The following diagram illustrates how the Compressor transcoding process works. The
largest transcoding component is a batch. The batch represents all the components
needed to transcode your current media. It must contain one or more jobs. A job
consists of at least one source media file with one or more settings and destinations
associated with it. After completing the transcoding process, the resulting file is known
as the output media file. One output media file is created for each setting assigned to a
source media file.
In the illustration below, the batch contains two source media files, each of which
contains two settings (making it a job). So, the total number of output files created by
transcoding this batch will be four. Job 1 will create two output media files, as will Job 2.
