Setting video and audio compression

When you send a podcast to iWeb or export a project as a QuickTime movie, you can apply different compression settings. Compression reduces the size of the exported file, making it easier to share or publish on the Internet. Reducing the file size also reduces the quality.

The Export pane of GarageBand Preferences gives you a variety of compression choices. Each setting is optimized for a different type of use.

To choose compression settings for a podcast or movie:

  1. Choose GarageBand > Preferences, then click Export.
  2. If your project contains a video file, choose the compression you want to use from the Movie Settings pop-up menu. Movie compression settings apply to both video and audio in your project.
  3. For audio podcasts, choose the compression you want to use from the Audio Podcast Settings pop-up menu.

Compression settings are saved as part of the project, and are applied each time you export or send the project. A project's compression settings remain the same regardless of whether you change them for another project.
