QuickTime is a multimedia framework originally developed by Apple Computer for its Macintosh line of computers.

Product historyEdit

QuickTime 1.0, codenamed "Warhol", was originally released for Macintosh System 6 in December 1991. Adobe Premiere 1.0 had also been in development by Randy Ubillos and was one of the first QuickTime-based video editors on the market.[1]

Apple released QuickTime 2.0 for System 7 in June 1994, the only commercial version that was not freely released. Version 2.5 was released on July 22nd of that year.[2]

ComponentsEdit

QuickTime MPEG ExtensionEdit

On January 24, 1997, Apple released the QuickTime MPEG Extension, which allowed playback of MPEG-1 video on Power Macintosh computers without the need for additional dedicated hardware.[3][4]

QuickTime Musical InstrumentsEdit

Adds MIDI support to QuickTime 2.0 and later. A companion QuickTime Music control panel and Macintosh MIDI Manager had also been in development for QuickTime 2.1, but were never released.[5]

QuickTime PowerPlugEdit

The PowerPlug extension accelerates performance of QuickTime 2.5 and later on systems with a PowerPC processor.[5]

QuickTime VREdit

QuickTime VR allowed for 360-degree navigation in multimedia titles.

DeprecationEdit

QuickTime 7 introduced QTKit in April 2005 as a new 64-bit framework in the transition leading up to QuickTime X.[6] Classic QuickTime (pre-X) and QTKit have since been deprecated in favor of AVFoundation and AVKit, which originated on Apple's iOS platform and have now become the default media framework for macOS.[7][8][9]

Apple discontinued QuickTime development for Windows since version 7.7.9,[10] leading the U.S. Computer Emergency Readiness Team to recommend the removal of obsolete versions of QuickTime from Windows computers due to the lack of future security updates.[11] Adobe discontinued support for the classic 32-bit versions of QuickTime and its legacy formats since April 2018 and ported the ProRes codecs of QuickTime X to support its Windows apps.[12][13]
