The term QuickTime also refers to the QuickTime Player front-end media player application, which is built-into macOS, and was available for download on Windows until 2016. QuickTime was created in 1991, when the concept of playing digital video directly on computers was "groundbreaking." QuickTime could embed a number of advanced media types, including panoramic images (called QuickTime VR) and Adobe Flash. Over the 1990s, QuickTime became a dominant standard for digital multimedia, as it was integrated into many websites, applications, and video games, and adopted by professional filmmakers. The QuickTime File Format became the basis for the MPEG-4 standard. During its heyday, QuickTime was notably used to create the innovative Myst and Xplora1 video games, and to exclusively distribute movie trailers for several Star Wars movies. QuickTime could support additional codecs through plug-ins, for example with Perian. Īs operating systems and browsers gained support for MPEG-4 and subsequent standards like H.264, the need for a cross-platform version of QuickTime diminished, and Apple discontinued the Windows version of QuickTime in 2016. In Mac OS X Snow Leopard, QuickTime 7 was discontinued in favor of QuickTime Player X, which abandoned the aging QuickTime framework in favor of the AVFoundation framework. QuickTime Player X does not support video editing (beyond trimming clips) or plug-ins for additional codec support. macOS Catalina dropped support for all 32-bit applications, including the QTKit framework and the old QuickTime 7. QuickTime for Microsoft Windows is downloadable as a standalone installation, and was bundled with Apple's iTunes prior to iTunes 10.5, but is no longer supported and therefore security vulnerabilities will no longer be patched. Already, at the time of the Windows version's discontinuation, two such zero-day vulnerabilities (both of which permitted arbitrary code execution) were identified and publicly disclosed by Trend Micro consequently, Trend Micro strongly advised users to uninstall the product from Windows systems. Software development kits (SDK) for QuickTime are available to the public with an Apple Developer Connection (ADC) subscription. It is available free of charge for both macOS operating systems. There are some other free player applications that rely on the QuickTime framework, providing features not available in the basic QuickTime Player. For example, iTunes can export audio in WAV, AIFF, MP3, AAC, and Apple Lossless. In addition, macOS has a simple AppleScript that can be used to play a movie in full-screen mode, but since version 7.2 full-screen viewing is now supported in the non-Pro version. This section needs expansion with: More information about the framework as a whole and about the platform-specific implementations of QuickTime (differences between Mac and Windows versions). Encoding and transcoding video and audio from one format to another.The QuickTime framework provides the following: Can use the book sources cited at the end. Decoding video and audio, then sending the decoded stream to the graphics or audio subsystem for playback.Command-line utilities afconvert (to convert audio formats), avconvert (to convert video formats) and qtmodernizer (to automatically convert older formats to H.264/AAC) are provided with macOS for power users. In macOS, QuickTime sends video playback to the Quartz Extreme (OpenGL) Compositor.
