QuickTime 105 QuickTime 4 If you are producing QuickTime 4 files, you can add URL links, use compressed movie headers to reduce download times and use high-quality codecs, such as Sorenson Video and QDesign Music. Viewers can view alternate versions of your movie if you create them. You can add interactivity to your projects and a QuickTime Effects track to your movie that is rendered upon playback. QuickTime 4 (and later) supports a very broad range of media types on both Mac OS and Windows, so you can use text tracks, sprites, and more for cross-platform titles. The one exception to this is MPEG-1, which is only supported under QuickTime 5 for Windows. QuickTime 5 If you require viewers to have QuickTime 5, you can use all the QuickTime features present in each of the Settings tabs. You can create realtime-streaming files and use more alternate movie criteria, such as language-based and CPU-based alternates. QuickTime 5 includes the Sorenson 3 codec. QuickTime 5 also enables use of alternates that work on the desktop, instead of only over the Web. QuickTime 6 QuickTime 6 includes the MPEG-4, AAC, and JPEG2000 codecs. When installed, these options will appear in the Settings window. QuickTime 7 QuickTime 7 includes the H.264 codec. Flattening Movies Flatten QuickTime movies before they are distributed. Flattening a movie does three things: •Makes the movie self-contained (There are no references to external files). •Optimizes the movie for playback by interleaving the media and putting the Table of Contents at the beginning of the file to make fast start work. You normally do not have to worry about flattening movies because all of Cleaner built-in QuickTime settings do it by default. Sometimes you need to flatten an existing movie without processing it. If you edit a movie with QuickTime Player, for example, by replacing its audio track with a different one and saving the result, the movie is incorrectly interleaved and is not viewable online until it is entirely downloaded. Therefore, you should flatten any movies that were altered in any way after processing prior to distribution. To address this, Cleaner makes it easy to flatten existing movies. You can make flattened copies of movies, or you can flatten the original movies in place.
