After you’ve configured jobs in your batch with the presets, job actions, locations, and filenames that you want, you can transcode the batch. A batch contains one or more jobs to be submitted to Compressor for transcoding.
When you select a batch, its properties are shown in the Batch inspector.
In Compressor, click the source file name(s) at the top of the batch area.
If necessary, click the Inspector button 
to reveal the inspector pane.
The batch properties are displayed in the Batch inspector:
Name: Identifies how the batch will appear in Active and Completed views once you start the batch. To change the batch name, type a new name in this field.
Jobs: Displays the number of jobs in the batch.
Outputs: Displays the number of files that will be output when transcoding the batch.
In Compressor, click the Start Batch button in the lower-right corner of the batch area and, if necessary, follow the instructions to complete the transcoding process.
The Compressor window switches to Active view, where you can monitor the transcoding process.
In Completed view, you can see how a file was transcoded.
In Compressor, click the Completed button at the top of the Compressor window.
Select a batch, job, or transcoded file and, if necessary, click the Inspector button .
In the inspector (on the right), you can view information about the batch or job, or view the general, video, or audio properties for the preset used to transcode the file.
To view the output file, click the Show in Finder button 
.
If the Show in Finder button is not visible, click the disclosure triangles on the left side of the Completed view window.
In Completed view in Compressor, click a job’s Reuse button 
.
All of the job’s information is copied to Current view, where you can modify the job’s preset properties and other information as necessary, then transcode the new job.
