The QuickTime plug-in works with existing QuickTime movies, and with movies prepared to take advantage of the plug-in's "fast-start" feature. The fast-start feature will present the first frame of the movie almost immediately and can begin playing even before the movie has been completely downloaded.
Netscape Navigator 3.0b7 or later uses the QuickTime plug-in automatically to play any QuickTime movie while browsing the Internet. The plug-in can play many kinds of QuickTime movies (.mov files) including movies with text, MIDI, and other kinds of data. If you have downloaded and installed the QuickTime VR component, it will also let you interact with QuickTime VR Panoramas and Objects.
