Manage layouts

1 Choose Window > Manage Layouts.

A dialog for managing layouts appears.

2 Do any of the following:

•

To rename a layout: Double-click it and type the new name.

•

To remove a layout: Select it and click the Delete (–) button.

•

To save the current interface conguration as a new layout: Click the Add (+) button and enter a

name for the layout.

•

To choose a layout and apply it to the current Compressor interface: Choose the layout and click

the Apply button.

3 When you’ve nished managing your layouts, click Done.

The dialog closes and the Compressor interface changes to match the chosen layout setting.

Note: The layouts list is actually divided into two sections—the ones supplied by Apple and the

ones that you create. You cannot rename or delete the Apple-supplied layouts. The ones that you

create are listed in alphabetical order. Use care when naming your layouts so that you can easily

locate them in the list.

Compressor terms

This section covers common terms that you’ll encounter as you use Compressor.

•

Codec: Short for COmpression/DECompression. A mathematical model for reducing the data of

a source media le.

•

File format: The output format used to transcode your source media le.

•

Transcoding: The process of converting les from their original format to output les ready for

distribution in another format. Closely related terms include compression, which specically

refers to data reduction, and encoding, a term that is essentially synonymous with transcoding,

but doesn’t emphasize the conversion aspect.

•

Source media le: The original media le to be converted to a new le format.

•

QuickTime: The cross-platform multimedia technology that allows OS X and Windows

applications to capture and play back video, audio, and still-image les. QuickTime les can

contain many dierent kinds of media and codecs. Codecs give instructions to QuickTime on

how to play back the media.
