QuickTime 107 CD-ROM Codecs For delivery on CD-ROM, use Sorenson Video or H.264 unless you're targeting slow computers. For very slow CPUs, Cinepak is a safe choice. For audio on CD-ROM, MP3 or IMA works well. DVD-ROM Codecs For DVD-ROM delivery, good choices are Sorenson Video, MPEG, or H.264. For DVD-Video, you must use MPEG-2. See "MPEG" on page 98. MP3 Unlike consumer MP3 encoders/rippers, Cleaner includes a professional MP3 encoder created by Fraunhofer, one of the inventors of the MP3 format. Cleaner enables you to use MP3s in the audio tracks of QuickTime movies by selecting MP3 from the Audio tab > Codec. For more information on MP3 files, see "MP3" on page 95. AAC The QuickTime AAC codec builds on signal processing technology from Dolby Laboratories and includes true VBR audio encoding. The characteristics of AAC include: • Perceptual audio codec, similar to MP3 • Multichannel capability • "Indistinguishable"audio quality that is, you can take an encoded file and the source from the encoded file and you should not be able to tell the difference over a stereo system. Audio-only Movies QuickTime is often used to deliver audio-only streams. To create an audio-only QuickTime file: 1. In the Tracks tab of the Settings window, uncheck all options except Audio. All video-related tabs will be hidden. 2. Select the encoding and audio processing parameters in the Audio tab. 3. Process the file as normal. You can embed and serve this file exactly as you would any other QuickTime movie. For more details on audio processing, see "The Audio Tab" on page 76.
