You can create your own custom settings, either based on an existing built-in or custom setting, or from scratch. You can also create groups of settings, rename a custom setting, or delete a custom setting.
To save a modified setting for future use, you must create a custom setting. The easiest way to do this is to duplicate a built-in setting and then modify its properties in the inspector.
In the Settings pane (press Shift-Command-1 if it’s hidden), select the setting that you want to duplicate.
To reveal individual settings in a setting category, click the disclosure triangle next to the category name.
Choose Duplicate from the Action pop-up menu 
at the bottom of the pane.
A copy of the setting (appended with the word, “copy”) appears in the Custom area of the Settings pane.
To modify the properties of your new custom setting, adjust the controls in the General, Video, and Audio inspectors.
If the inspector is hidden, click the Inspector button 
in the upper-right corner of the Compressor window.
For example, you can change a setting’s frame controls or add a video or audio effect to the output file. To learn more a setting’s properties, see About formats and settings.
You can also create a custom setting without duplicating a built-in setting. Because it’s easy to accidentally introduce transcoding errors, this method is recommended for advanced users only.
In the Settings pane (press Shift-Command-1 if it’s hidden), click the Add pop-up menu 
, then choose New Setting.
In the dialog that appears, choose a transcoding format from the pop-up menu, enter a name and description for the setting, then click OK.
The new setting appears in the Custom area of the Settings pane.
To modify the properties of your new custom setting, adjust the controls in the General, Video, and Audio inspectors.
If the inspector is hidden, click the Inspector button in the upper-right corner of the Compressor window. For example, you can change a setting’s frame controls or add a video or audio effect to the output file.
To learn more about setting properties, see About formats and settings.
If you want to organize your custom settings, you can create a setting group. For example, if you want to quickly add several settings at the same time, you can apply a setting group to a job.
In the Settings pane (press Shift-Command-1 if it’s hidden), click the Add pop-up menu , then choose New Group.
In the dialog that appears, type a name for the group and click OK.
The group appears in the Custom area of the Settings pane and is selected by default.
Drag custom settings from the Custom area of the Settings pane into your new group.
You can add only custom settings to a custom group. If you want to add a built-in setting to the group, you must duplicate the setting (as described in Create a custom setting by duplicating an existing setting above), then add the duplicated setting to your group.
You can save a custom setting as a file and share it with colleagues or move it from one system to another.
Drag a setting from the Settings pane in Compressor to the Desktop.
The setting will be saved as a file, which can then be moved, copied, emailed or otherwise transferred to another user’s Mac. The recipient just needs to drag the file into the Custom folder of the Settings pane in Compressor.
Tip: You can even drag the custom setting directly to (and from) the body of an email message in Mail.
Do one of the following:
In the Settings pane, double-click a custom setting, type a new name, then press Return.
Select a custom setting in the Settings pane, then, in the General inspector, type a new name in the Name field. (If the inspector is hidden, press Command-4.)
Select a custom setting in the Settings pane, then press Delete.
