A multi-platformstandard for multimedia applications. Developed by Apple, QuickTime is a software program that handles video, sound, animation, graphics, text, music, and 360-degree virtual reality (VR) scenes. It is a gateway for rich media, including images, music, MIDI, MP3, and streaming audio. QuickTime lets you experience more than 200 kinds of digital media with your Mac or PC. It allows users to experience virtual reality on a desktop without any special equipment and to view 3-D photographic (or rendered) representations of any person, place, or thing. (You can use your mouse and keyboard to rotate objects, zoom in and out of a scene, look around 360 degrees, and navigate from one scene to another.) QuickTime file name extensions include .qt and .mov.
