Apple released Quick Time 1.5 for Mac OS in the latter part of 1992.
This added the Super Mac-developed Cinepak vector-quantization video codec (initially known as Compact Video).
Software development kits (SDK) for Quick Time are available to the public with an Apple Developer Connection (ADC) subscription.
It is available free of charge for both mac OS and Windows operating systems.
In addition, mac OS has a simple Apple Script that can be used to play a movie in full-screen mode, Quick Time Player 7 is limited to only basic playback operations unless a Quick Time Pro license key is purchased from Apple.
Until recently, Apple's professional applications (e.g. Final Cut Studio, Logic Studio) included a Quick Time Pro license.
Advanced Simple Profile (ASP) features, like B-frames, were unsupported (in contrast with, for example, encoders such as Xvi D or 3ivx).
Quick Time 7 supports the H.264 encoder and decoder.
and it is named in Annex D (informative) in MPEG-4 Part 12.
By 2000, MPEG-4 formats became industry standards, first appearing with support in Quick Time 6 in 2002.
First made in 1991, the latest Mac version, Quick Time X, is currently available on Mac OS X Snow Leopard and newer.
Apple ceased support for the Windows version of Quick Time in 2016. Quick Time for Microsoft Windows is downloadable as a standalone installation, and was bundled with Apple's i Tunes prior to i Tunes 10.5, but is no longer supported and therefore security vulnerabilities will no longer be patched.
Quick Time 7 now supports multi-channel AAC-LC and HE-AAC audio (used, for example, in the high-definition trailers on Apple's site), for both . The lead developer of Quick Time, Bruce Leak, ran the first public demonstration at the May 1991 Worldwide Developers Conference, where he played Apple's famous 1984 advertisment in a window at 320×240 pixels resolution.
