Supported Formats

iTunes U supports the distribution of compressed audio and video files. Apple recommends using the following formats for your iTunes U audio and video content:

You can also use iTunes U to distribute Portable Document Format (PDF) and electronic publication (ePub) files. ePub files must pass ePubCheck 1.0.5, include only files listed in the manifest, and use UTF-8/16 characters. For more details, read the complete ePub specification at http://www.idpf.org/specs.htm . PDF and ePub files appear in iTunes U and the iTunes U library with a book icon. To open a PDF or ePub file, download the file and double-click the file. iBooks or another reader is required (download the free iBooks application from the App store). You cannot preview a PDF or ePub file in iTunes U.

iTunes U supports images embedded in tracks in JPEG, PNG, or GIF format with appropriate file extensions (.jpg, .jpeg, .png, .gif) in RGB Color Model. JPEG images can include EXIF or JFIF, but not both.

If you host your content on a server using an SSL URL scheme (https), be sure to set up a valid certificate. If iTunes U cannot obtain a verifiable certificate the request fails. If you cannot set up a valid certificate, switch your content to a server using a non-SSL URL scheme.

If you are using QuickTime to create and edit video content, Apple recommends that you export your videos by choosing “Movie to iPod” from the Export pop-up menu in QuickTime Pro. For more information, see http://www.apple.com/quicktime/ .
