A number of additional features and enhancements have also been included in this release. These are intended to benefit both content providers and end users. In brief, QuickTime 4.1 includes the following changes: I Added 64-bit file support for Mac OS 9, which enables recording and playback of movie files larger than 2 gigabytes (2G) on Mac OS 9. I Added support for Synchronized Multimedia Integration Language (SMIL), a simple, text-based format defined by W3C <http://www.w3.org/TR/ REC-smil/> which lets you create presentations out of diverse media elements –– any media that QuickTime supports. Content providers can now Summary of Changes and Enhancements 9 RELEASE 1.0 What’s New in QuickTime 4.1 insert advertising content in a sequence of streams, using QuickTime 4.1’s implementation of the SMIL standard. I Added the capability of movies to embed other movies as a track, which means that movies may now contain other movies which may have independent clocks. This is accomplished by means of a new Movie Media Handler API.
