If you want to stream a QuickTime movie using QuickTime Streaming Server, you

should use a web-optimized video or audio compressor to compress the movie file. All

QuickTime compressors are compatible with QuickTime Streaming Server, but the

compressors listed here are optimized to give the best results for delivery over the

Internet. For a complete list of compressors that QuickTime supports, see the Products

area of the QuickTime website (www.apple.com/quicktime/products).

Â Video compressors: H.264, MPEG-4, Sorenson Video (any version), H.263, H.261

Â Audio compressors: AAC, QUALCOMM PureVoice, AMR, QDesign

Creating Reference Movies to Optimize Web Playback

You can use reference movies to provide the appropriate movie for different users’

connection speeds. For example, you can have a smaller movie streamed to users

connected over a standard modem, and a larger version of the movie streamed to

users connected over a broadband connection.

Apple provides a free tool, MakeRefMovie X, that greatly simplifies the process of

creating reference movies. You can download this software at:

For more information about reference movies see “Creating Movies Optimized for

iPhone and Web Delivery” on page 48
