QuickTime

December 18, 2023

For the gameplay mechanic in video games, see Quick time event.

QuickTime is a discontinued[1] extensible multimedia architecture created by Apple, which supports playing, streaming, encoding, and transcoding a variety of digital media formats.[2][3] The term QuickTime also refers to the QuickTime Player front-end media player application,[2] which is built-into macOS, and was formerly available for Windows.[4]

QuickTime was created in 1991, when the concept of playing digital video directly on computers was "groundbreaking."[2][3] 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.[5][6][2][3][7] 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.[8][2] QuickTime could support additional codecs through plug-ins, for example with Perian.[9]

As 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.[10][11][12][1] 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.[1][13] macOS Catalina dropped support for all 32-bit applications, including the QTKit framework and the old QuickTime 7.[11]

Overview edit

QuickTime is bundled with macOS. QuickTime for Microsoft Windows was 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.[14] 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.[15][16]

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,[17] but since version 7.2 full-screen viewing is now supported in the non-Pro version.[18]

QuickTime framework edit

The QuickTime framework provides the following:

  • Encoding and transcoding video and audio from one format to another. 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.
  • Decoding video and audio, then sending the decoded stream to the graphics or audio subsystem for playback. In macOS, QuickTime sends video playback to the Quartz Extreme (OpenGL) Compositor.[19]
  • A "component" plug-in architecture for supporting additional 3rd-party codecs (such as DivX).

As of early 2008, the framework hides many older codecs listed below from the user although the option to "Show legacy encoders" exists in QuickTime Preferences to use them.[20] The framework supports the following file types and codecs natively:[21]

Audio Video Picture

Due to macOS Mojave being the last version to include support for 32-bit APIs and Apple's plans to drop 32-bit application support in future macOS releases, many codecs will no longer be supported in newer macOS releases, starting with macOS Catalina, which was released on October 7, 2019.

As of Mac OS X Lion, the underlying media framework for QuickTime, QTKit, was deprecated in favor of a newer graphics framework, AVFoundation, and completely discontinued as of macOS Catalina.[23]

Windows edit

PictureViewer is a component of QuickTime for Microsoft Windows and the Mac OS 8 and Mac OS 9 operating systems. It is used to view picture files from the still image formats that QuickTime supports. In macOS, it is replaced by Preview.[24][25]

Irix edit

A version of QuickTime for the Irix operating system running on SGI hardware with MIPS processors was developed in the mid-1990s but never released.

QuickTime Player edit

QuickTime 7 Pro edit

QuickTime Player 7 is limited to only basic playback operations unless a QuickTime Pro license key is purchased from Apple. Until Catalina, Apple's professional applications (e.g. Final Cut Studio, Logic Studio) included a QuickTime Pro license. Pro keys are specific to the major version of QuickTime for which they are purchased and unlock additional features of the QuickTime Player application on macOS or Windows.[26] The Pro key does not require any additional downloads; entering the registration code immediately unlocks the hidden features.

QuickTime 7 is still available for download from Apple, but as of mid-2016, Apple stopped selling registration keys for the Pro version.

Features enabled by the Pro license include, but are not limited to:

  • Editing clips through the cut, copy and paste functions, merging separate audio and video tracks, and freely placing the video tracks on a virtual canvas with the options of cropping and rotation.
  • Saving and exporting (encoding) to any of the codecs supported by QuickTime. QuickTime 7 includes presets for exporting video to a video-capable iPod, Apple TV, and the iPhone.
  • Saving existing QuickTime movies from the web directly to a hard disk drive. This is often, but not always, either hidden or intentionally blocked in the standard mode. Two options exist for saving movies from a web browser:
    • Save as source – This option will save the embedded video in its original format. (I.e. not limited to .mov files.)
    • Save as QuickTime movie – This option will save the embedded video in a .mov file format no matter what the original container is/was.

Mac OS X Snow Leopard includes QuickTime X. QuickTime Player X lacks cut, copy and paste and will only export to four formats, but its limited export feature is free. Users do not have an option to upgrade to a Pro version of QuickTime X, but those who have already purchased QuickTime 7 Pro and are upgrading to Snow Leopard from a previous version of Mac OS X will have QuickTime 7 stored in the Utilities or user defined folder. Otherwise, users will have to install QuickTime 7 from the "Optional Installs" directory of the Snow Leopard DVD after installing the OS.

Mac OS X Lion and later also include QuickTime X. No installer for QuickTime 7 is included with these software packages, but users can download the QuickTime 7 installer from the Apple support site. QuickTime X on later versions of macOS support cut, copy and paste functions similarly to the way QuickTime 7 Pro did; the interface has been significantly modified to simplify these operations, however.

On September 24, 2018, Apple ended support for QuickTime 7 and QuickTime Pro, and updated many download and support pages on their website to state that QuickTime 7 "will not be compatible with future macOS releases."

File formats edit

Main article: QuickTime File Format

The native file format for QuickTime video, QuickTime File Format, specifies a multimedia container file that contains one or more tracks, each of which stores a particular type of data: audio, video, effects, or text (e.g. for subtitles). Each track either contains a digitally encoded media stream (using a specific format) or a data reference to the media stream located in another file. The ability to contain abstract data references for the media data, and the separation of the media data from the media offsets and the track edit lists means that QuickTime is particularly suited for editing, as it is capable of importing and editing in place (without data copying).

Other file formats that QuickTime supports natively (to varying degrees) include AIFF, WAV, DV-DIF, MP3, and MPEG program stream. With additional QuickTime Components, it can also support ASF, DivX Media Format, Flash Video, Matroska, Ogg, and many others.

QuickTime and MPEG-4 edit

On February 11, 1998, the ISO approved the QuickTime file format as the basis of the MPEG‑4 file format.[27] The MPEG-4 file format specification was created on the basis of the QuickTime format specification published in 2001.[28] The MP4 (.mp4) file format was published in 2001 as the revision of the MPEG-4 Part 1: Systems specification published in 1999 (ISO/IEC 14496-1:2001).[29][30][31] In 2003, the first version of MP4 format was revised and replaced by MPEG-4 Part 14: MP4 file format (ISO/IEC 14496-14:2003).[32] The MP4 file format was generalized into the ISO Base Media File Format ISO/IEC 14496-12:2004, which defines a general structure for time-based media files. It in turn is used as the basis for other multimedia file formats (for example 3GP, Motion JPEG 2000).[33][34][35][36][37] A list of all registered extensions for ISO Base Media File Format is published on the official registration authority website www.mp4ra.org. This registration authority for code-points in "MP4 Family" files is Apple Computer Inc. and it is named in Annex D (informative) in MPEG-4 Part 12.[36]

By 2000, MPEG-4 formats became industry standards, first appearing with support in QuickTime 6 in 2002. Accordingly, the MPEG-4 container is designed to capture, edit, archive, and distribute media, unlike the simple file-as-stream approach of MPEG-1 and MPEG-2.[38]

Profile support edit

QuickTime 6 added limited support for MPEG-4, specifically encoding and decoding using Simple Profile (SP). Advanced Simple Profile (ASP) features, like B-frames, were unsupported (in contrast with, for example, encoders such as XviD or 3ivx). QuickTime 7 supports the H.264 encoder and decoder.[39]

Container benefits edit

Because both MOV and MP4 containers can use the same MPEG-4 codecs, they are mostly interchangeable in a QuickTime-only environment. MP4, being an international standard, has more support. This is especially true on hardware devices, such as the Sony PSP and various DVD players, on the software side, most DirectShow / Video for Windows codec packs[40][41] include a MP4 parser, but not one for MOV.

In QuickTime Pro's MPEG-4 Export dialog, an option called "Passthrough" allows a clean export to MP4 without affecting the audio or video streams. QuickTime 7 now supports multi-channel AAC-LC and HE-AAC audio (used, for example, in the high-definition trailers on Apple's site),[42] for both .MOV and .MP4 containers.

History edit

Apple released the first version of QuickTime on December 2, 1991, as a multimedia add-on for System 6 and later. The lead developer of QuickTime, Bruce Leak, ran the first public demonstration at the May 1991 Worldwide Developers Conference, where he played Apple's famous 1984 advertisement in a window at 320×240 pixels resolution.

QuickTime 1.x edit

The original video codecs included:

The first commercial project produced using QuickTime 1.0 was the CD-ROM . The first publicly visible use of QuickTime was Ben & Jerry's interactive factory tour (dubbed The Rik & Joe Show after its in-house developers). The Rik and Joe Show was demonstrated onstage at MacWorld in San Francisco when John Sculley announced QuickTime.[44]

Apple released QuickTime 1.5 for Mac OS in the latter part of 1992. This added the SuperMac-developed Cinepak vector-quantization video codec (initially known as Compact Video). It could play video at 320×240 resolution at 30 frames per second on a 25 MHz Motorola 68040 CPU. It also added text tracks, which allowed for captioning, lyrics and other potential uses.

Apple contracted San Francisco Canyon Company to port QuickTime to the Windows platform.[45] Version 1.0 of QuickTime for Windows provided only a subset of the full QuickTime API, including only movie playback functions driven through the standard movie controller.

QuickTime 1.6 came out the following year. Version 1.6.2 first incorporated the "QuickTime PowerPlug" which replaced some components with PowerPC-native code when running on PowerPC Macs.

QuickTime 2.x edit

Apple released QuickTime 2.0 for System Software 7 in June 1994—the only version never released for free. It added support for music tracks, which contained the equivalent of MIDI data and which could drive a sound-synthesis engine built into QuickTime itself (using a limited set of instrument sounds licensed from Roland), or any external MIDI-compatible hardware, thereby producing sounds using only small amounts of movie data.

Following Bruce Leak's departure to Web TV, the leadership of the QuickTime team was taken over by Peter Hoddie.

QuickTime 2.0 for Windows appeared in November 1994 under the leadership of Paul Charlton. As part of the development effort for cross-platform QuickTime, Charlton (as architect and technical lead), along with ace individual contributor Michael Kellner and a small highly effective team including Keith Gurganus, ported a subset of the Macintosh Toolbox to Intel and other platforms (notably, MIPS and SGI Unix variants) as the enabling infrastructure for the QuickTime Media Layer (QTML) which was first demonstrated at the Apple Worldwide Developers Conference (WWDC) in May 1996. The QTML later became the foundation for the Carbon API which allowed legacy Macintosh applications to run on the Darwin kernel in Mac OS X.[citation needed]

The next versions, 2.1 and 2.5, reverted to the previous model of giving QuickTime away for free. They improved the music support and added sprite tracks which allowed the creation of complex animations with the addition of little more than the static sprite images to the size of the movie. QuickTime 2.5 also fully integrated QuickTime VR 2.0.1 into QuickTime as a QuickTime extension. On January 16, 1997, Apple released the QuickTime MPEG Extension (PPC only) as an add-on to QuickTime 2.5, which added software MPEG-1 playback capabilities to QuickTime.

Lawsuit against San Francisco Canyon edit

Main article: San Francisco Canyon Company

In 1994, Apple filed suit against software developer San Francisco Canyon for intellectual property infringement and breach of contract.[46] Apple alleged that San Francisco Canyon had helped develop Video for Windows using several hundred lines of unlicensed QuickTime source code. They were contracted by Intel to help make Video for Windows better use system resources on Intel processors, which was subsequently unilaterally removed.[45] Microsoft and Intel were added to the lawsuit in 1995. The suit ended in a settlement in 1997.

QuickTime 3.x edit

The release of QuickTime 3.0 for Mac OS on March 30, 1998, introduced the now-standard revenue model of releasing the software for free, but with additional features of the Apple-provided MoviePlayer application that end-users could only unlock by buying a QuickTime Pro license code. Since the "Pro" features were the same as the existing features in QuickTime 2.5, any previous user of QuickTime could continue to use an older version of the central MoviePlayer application for the remaining lifespan of Mac OS to 2002, indeed, since these additional features were limited to MoviePlayer, any other QuickTime-compatible application remained unaffected.

QuickTime 3.0 added support for graphics importer components that could read images from GIF, JPEG, TIFF, and other file formats, and video output components which served primarily to export movie data via FireWire. Apple also licensed several third-party technologies for inclusion in QuickTime 3.0, including the Sorenson Video codec for advanced video compression, the QDesign Music codec for substantial audio compression, and the complete Roland Sound Canvas instrument set and GS Format extensions for improved playback of MIDI music files. It also added video effects which programmers could apply in real-time to video tracks. Some of these effects would even respond to mouse clicks by the user, as part of the new movie interaction support (known as wired movies).

QuickTime interactive edit

During the development cycle for QuickTime 3.0, part of the engineering team was working on a more advanced version of QuickTime to be known as QuickTime interactive or QTi. Although similar in concept to the wired movies feature released as part of QuickTime 3.0, QuickTime interactive was much more ambitious. It allowed any QuickTime movie to be a fully interactive and programmable container for media. A special track type was added that contained an interpreter for a custom programming language based on 68000 assembly language. This supported a comprehensive user interaction model for mouse and keyboard event handling based in part on the AML language from the Apple Media Tool.

The QuickTime interactive movie was to have been the playback format for the next generation of HyperCard authoring tool. Both the QuickTime interactive and the HyperCard 3.0 projects were canceled in order to concentrate engineering resources on streaming support for QuickTime 4.0, and the projects were never released to the public.

QuickTime 4.x edit

Apple released QuickTime 4.0 on June 8, 1999[47] for Mac OS 7.5.5 through 8.6 (later Mac OS 9) and Windows 95, Windows 98, and Windows NT. Three minor updates (versions 4.0.1, 4.0.2, and 4.0.3) followed.[48] It introduced features that most users now consider basic:[49]

  • Graphics exporter components, which could write some of the same formats that the previously introduced importers could read. (GIF support was omitted, possibly because of the LZW patent.)
  • Support for the QDesign Music 2 and MPEG-1 Layer 3 audio (MP3).
  • QuickTime 4 was the first version to support streaming. It was accompanied by the release of the free QuickTime Streaming Server version 1.0.
  • QuickTime 4 Player introduced brushed metal to the Macintosh user interface.

On December 17, 1999, Apple provided QuickTime 4.1, this version's first major update.[47] Two minor versions (4.1.1 and 4.1.2) followed.[50] The most notable improvements in the 4.1.x family were:[51]

  • Support for files larger than 2.0 GB in Mac OS 9. (This is a consequence of Mac OS 9 requiring the HFS Plus filesystem.[52])
  • Variable bit rate (VBR) support for MPEG-1 Layer 3 (MP3) audio.
  • Support for Synchronized Multimedia Integration Language (SMIL).
  • Introduction of AppleScript support in Mac OS.
  • The requirement of a PowerPC processor for Mac OS systems. QuickTime 4.1 dropped support for Motorola 68k Macintosh systems.

QuickTime 5.x edit

QuickTime 5 was one of the shortest-lived versions of QuickTime, released in April 2001 and superseded by QuickTime 6 a little over a year later. This version was the last to have greater capabilities under Mac OS 9 than under Mac OS X, and the last version of QuickTime to support Mac OS versions 7.5.5 through 8.5.1 on a PowerPC Mac and Windows 95. Version 5.0 was initially only released for Mac OS and Mac OS X on April 14, 2001, and version 5.0.1 followed shortly thereafter on April 23, 2001, supporting the classic Mac OS, Mac OS X, and Windows.[53] Three more updates to QuickTime 5 (versions 5.0.2, 5.0.4, and 5.0.5) were released over its short lifespan.

QuickTime 5 delivered the following enhancements:[54]

  • MPEG-1 playback for Windows, and updated MPEG-1 Layer 3 audio support for all systems.
  • Sorenson Video 3 playback and export[55] (added with the 5.0.2 update).[56]
  • Realtime rendering of effects & transitions in DV files, including enhancements to DV rendering, multiprocessor support, and Altivec enhancements for PowerPC G4 systems.
  • Flash 4 playback and export.
  • A new QuickTime VR engine, adding support for cubic VR panoramas.

QuickTime 6.x edit

On July 15, 2002, Apple released QuickTime 6.0, providing the following features:[57]

  • MPEG-4 playback, import, and export, including MPEG-4 Part 2 video and AAC Audio.
  • Support for Flash 5, JPEG 2000, and improved Exif handling.
  • Instant-on streaming playback.
  • MPEG-2 playback (via the purchase of Apple's MPEG-2 Playback Component).
  • Scriptable ActiveX control.

QuickTime 6 was initially available for Mac OS 8.6 – 9.x, Mac OS X (10.1.5 minimum), and Windows 98, Me, 2000, and XP. Development of QuickTime 6 for Mac OS slowed considerably in early 2003, after the release of Mac OS X v10.2 in August 2002. QuickTime 6 for Mac OS continued on the 6.0.x path, eventually stopping with version 6.0.3.[58]

QuickTime 6.1 & 6.1.1 for Mac OS X v10.1 and Mac OS X v10.2 (released October 22, 2002)[59] and QuickTime 6.1 for Windows (released March 31, 2003)[60] offered ISO-Compliant MPEG-4 file creation and fixed the vulnerability.

Apple released QuickTime 6.2 exclusively for Mac OS X on April 29, 2003, to provide support for iTunes 4, which allowed AAC encoding for songs in the iTunes library.[61] (iTunes was not available for Windows until October 2003.)

On June 3, 2003, Apple released QuickTime 6.3, delivering the following:[62]

  • Support for 3GPP, including 3G Text, video, and audio (AAC and AMR codecs).
  • Support for the .3gp, .amr, and .sdv file formats via separate component.

QuickTime 6.4, released on October 16, 2003, for Mac OS X v10.2, Mac OS X v10.3, and Windows, added the following:[63]

  • Addition of the Apple Pixlet codec (only for Mac OS X v10.3 and later).
  • ColorSync support.
  • Integrated 3GPP.

On December 18, 2003, Apple released QuickTime 6.5, supporting the same systems as version 6.4. Versions 6.5.1 and 6.5.2 followed on April 28, 2004, and October 27, 2004. These versions would be the last to support Windows 98 and Me. The 6.5 family added the following features:[64]

  • 3GPP2 and AMC mobile multimedia formats.
  • QCELP voice code.
  • Apple Lossless (in version 6.5.1[65][66]).

QuickTime 6.5.3 was released on October 12, 2005, for Mac OS X v10.2.8 after the release of QuickTime 7.0, fixing a number of security issues.

QuickTime 7.x edit

 
QuickTime Player 7.6.6 playing Big Buck Bunny running on Microsoft Windows

Initially released on April 29, 2005, in conjunction with Mac OS X v10.4 (for version 10.3.9 and 10.4.x), QuickTime 7.0 featured the following:[67][68]

After a couple of preview Windows releases,[70] Apple released 7.0.2 as the first stable release on September 7, 2005, for Windows 2000 and Windows XP. Version 7.0.4, released on January 10, 2006, was the first universal binary version. But it suffered numerous bugs, including a buffer overrun, which is more problematic to most users.

Apple dropped support for Windows 2000 with the release of QuickTime 7.2 on July 11, 2007.[71] The last version available for Windows 2000, 7.1.6, contains numerous security vulnerabilities.[72] References to this version have been removed from the QuickTime site, but it can be downloaded from Apple's support section.[73] Apple has not indicated that they will be providing any further security updates for older versions. QuickTime 7.2 is the first version for Windows Vista.

Apple dropped support for Flash content in QuickTime 7.3, breaking content that relied on Flash for interactivity, or animation tracks. Security concerns seem to be part of the decision.[74] Flash flv files can still be played in QuickTime if the free Perian plugin is added.

In QuickTime 7.3, a processor that supports SSE is required. QuickTime 7.4 does not require SSE. Unlike versions 7.2 and 7.3, QuickTime 7.4 cannot be installed on Windows XP without service packs or with Service Pack 1/1A installed (its setup program checks if Service Pack 2 is installed).

QuickTime 7.5 was released on June 10, 2008.[75] QuickTime 7.5.5 was released on September 9, 2008,[76] which requires Mac OS X v10.4 or higher, dropping 10.3 support. QuickTime 7.6 was released on January 21, 2009.[77] QuickTime 7.7 was released on August 3, 2011.[78]

QuickTime 7.6.6 is available for OS X, 10.6.3 Snow Leopard until 10.14 Mojave, as 10.15 Catalina will only support 64-bit applications.[79] There is a 7.7 release of QuickTime 7 for OS X, but it is only for Leopard 10.5.[80]

QuickTime 7.7.6 is the last release for Windows XP. As it's since version 7.4, they can be installed here only when Service Pack 2 or 3 is installed.

QuickTime 7.7.9 is the last Windows release of QuickTime. Apple stopped supporting QuickTime on Windows afterwards.[14]

Safari 12, released on September 17, 2018, for macOS Sierra and macOS High Sierra (and the default browser included on macOS Mojave released on September 24, 2018), which drops support for NPAPI plug-ins (except for Adobe Flash) dropped its support for QuickTime 7's web plugin. On September 24, 2018, Apple dropped support for the macOS version of QuickTime 7. This effectively marked the end of the technology in Apple's codec and web development.

Starting with macOS Catalina, QuickTime 7 applications, image, audio and video codecs will no longer be compatible with macOS or supported by Apple.

QuickTime X (QuickTime Player v10.x) edit

QuickTime X (pronounced QuickTime Ten)[81] was initially demonstrated at WWDC on June 8, 2009, and shipped with Mac OS X v10.6.[82]

It includes visual chapters,[83] conversion, sharing to YouTube, video editing,[84] capture of video and audio streams, screen recording,[85] GPU acceleration, and live streaming.[86]

But it removed support for various widely used formats, in particular the omission of MIDI caused significant inconvenience and trouble to many musicians and their potential audiences.[87]

In addition, a screen recorder is featured which records whatever is on the screen. However it is not possible to capture certain Digital rights management protected content. This includes iTunes/Apple TV video purchases, or any content protected by Apple's FairPlay DRM technology. While Safari uses FairPlay, Google Chrome and Firefox use Widevine for DRM, whose content is not protected from QuickTime screen capturing.

The reason for the jump in numbering from 7 to 10 (X) was to indicate a similar break with the previous versions of the product that Mac OS X indicated. QuickTime X is fundamentally different from previous versions, in that it is provided as a Cocoa (Objective-C) framework and breaks compatibility with the previous QuickTime 7 C-based APIs that were previously used. QuickTime X was completely rewritten to implement modern audio video codecs in 64-bit. QuickTime X is a combination of two technologies: QuickTime Kit Framework (QTKit) and QuickTime X Player. QTKit is used by QuickTime player to display media. QuickTime X does not implement all of the functionality of the previous QuickTime as well as some of the codecs. When QuickTime X attempts to operate with a 32-bit codec or perform an operation not supported by QuickTime X, it will start a 32-bit helper process to perform the requested operation. The website Ars Technica revealed that QuickTime X uses QuickTime 7.x via QTKit to run older codecs that have not made the transition to 64-bit.[88]

QuickTime X does not support .SRT subtitle files.[89] It has been suggested using the program Subler to interleave the MP4 and SRT files will fix this oversight, which can be downloaded at Bitbucket.[90]

QuickTime 7 may still be required to support older formats on Snow Leopard such as QTVR, interactive QuickTime movies, and MIDI files. In such cases, a compatible version of QuickTime 7 is included on Snow Leopard installation disc and may be installed side-by-side with QuickTime X. Users who have a Pro license for QuickTime 7 can then activate their license.[91]

A Snow Leopard compatible version of QuickTime 7 may also be downloaded from Apple Support website.[92]

The software got an increment with the release of Mavericks, and as of August 2018, the current version is v10.5. It contains more sharing options (email, YouTube, Facebook, Flickr etc.), more export options (including web export in multiple sizes, and export for iPhone 4/iPad/Apple TV (but not Apple TV 2). It also includes a new way of fast forwarding through a video and mouse support for scrolling.[93]

Starting with macOS Catalina, Apple only provides QuickTime X, as QuickTime 7 was never updated to 64-bit, affecting many applications, image, audio, and video formats utilizing QuickTime 7, and compatibility with these codecs in QuickTime X.

Creating software that uses QuickTime edit

QuickTime X edit

QuickTime X previously provided the QTKit Framework on Mac OS 10.6 until 10.14.[112] Since the release of macOS 10.15, AVKit and AVFoundation are used instead (due to the removal of 32-bit audio and video codecs, as well as image formats and APIs supported by QuickTime 7).

Previous versions edit

QuickTime consists of two major subsystems: the Movie Toolbox and the Image Compression Manager. The Movie Toolbox consists of a general API for handling time-based data, while the Image Compression Manager provides services for dealing with compressed raster data as produced by video and photo codecs.

Developers can use the QuickTime software development kit (SDK) to develop multimedia applications for Mac or Windows with the C programming language or with the Java programming language (see QuickTime for Java), or, under Windows, using COM/ActiveX from a language supporting this.

The COM/ActiveX option was introduced as part of QuickTime 7 for Windows and is intended for programmers who want to build standalone Windows applications using high-level QuickTime movie playback and control with some import, export, and editing capabilities. This is considerably easier than mastering the original QuickTime C API.[113]

QuickTime 7 for Mac introduced the QuickTime Kit (aka QTKit), a developer framework that is intended to replace previous APIs for Cocoa developers. This framework is for Mac only, and exists as Objective-C abstractions around a subset of the C interface. Mac OS X v10.5 extends QTKit to full 64-bit support. The QTKit allows multiplexing between QuickTime X and QuickTime 7 behind the scenes so that the user need not worry about which version of QuickTime they need to use.

Bugs and vulnerabilities edit

QuickTime 7.4 was found to disable Adobe's video compositing program, After Effects.[114][115][116] This was due to the DRM built into version 7.4 since it allowed movie rentals from iTunes. QuickTime 7.4.1 resolved this issue.[117]

Versions 4.0 through 7.3 contained a buffer overflow bug which could compromise the security of a PC using either the QuickTime Streaming Media client, or the QuickTime player itself.[118] The bug was fixed in version 7.3.1.

QuickTime 7.5.5 and earlier are known to have a list of significant vulnerabilities that allow a remote attacker to execute arbitrary code or cause a denial of service (out-of-bounds memory access and application crash) on a targeted system. The list includes six types of buffer overflow,[119][120][121][122][123][124] data conversion,[125] signed vs. unsigned integer mismatch,[126] and uninitialized memory pointer.[127]

QuickTime 7.6 has been found to disable Mac users' ability to play certain games, such as Civilization IV and The Sims 2. There are fixes available from the publisher, Aspyr.[128]

QuickTime 7 lacks support for H.264 Sample Aspect Ratio.[129] QuickTime X does not have this limitation,[citation needed] but many Apple products (such as Apple TV) still use the older QuickTime 7 engine. iTunes previously utilized QuickTime 7, but as of October 2019, iTunes no longer utilizes the older QuickTime 7 engine.[130]

QuickTime 7.7.x on Windows fails to encode H.264 on multi-core systems with more than approximately 20 threads, e.g. HP Z820 with 2× 8-core CPUs. A suggested solution[by whom?] is to disable hyper-threading/limit CPU cores. Encoding speed and stability depends on the scaling of the player window.[citation needed]

On April 14, 2016, Christopher Budd of Trend Micro announced that Apple has ceased all security patching of QuickTime for Windows, and called attention to two Zero Day Initiative advisories, ZDI-16-241 [131] and ZDI-16-242,[132] issued by Trend Micro's subsidiary TippingPoint on that same day.[15] Also on that same day, the United States Computer Emergency Readiness Team issued alert TA16-105A, encapsulating Budd's announcement and the Zero Day Initiative advisories.[16] Apple responded with a statement that QuickTime 7 for Windows is no longer supported by Apple.[14]

Windows 4 QuickTime was created in 1991 when the concept of playing digital video directly on computers was groundbreaking 2 3 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 5 6 2 3 7 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 8 2 QuickTime could support additional codecs through plug ins for example with Perian 9 As 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 10 11 12 1 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 1 13 macOS Catalina dropped support for all 32 bit applications including the QTKit framework and the old

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 14 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 15 16 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

Mac OS X will have QuickTime 7 stored in the Utilities or user defined folder Otherwise users will have to install QuickTime 7 from the Optional Installs directory of the Snow Leopard DVD after installing the OS Mac OS X Lion and later also include QuickTime X No installer for QuickTime 7 is included with these software packages but users can download the QuickTime 7 installer from the Apple

operations however On September 24 2018 Apple ended support for QuickTime 7 and QuickTime Pro and updated many download and support pages on their website to state that QuickTime 7 will not be compatible with future macOS releases File formats editMain article QuickTime File Format The native file format for QuickTime video QuickTime File Format specifies a multimedia container file that contains one or more tracks each of which stores a particular type of data audio video effects or text e g for subtitles Each track either contains a digitally encoded media stream using a specific format or a data reference to the media stream located in another file The ability to contain abstract data references for the media data and the separation of the media data from the media offsets and the track edit lists means that QuickTime is particularly suited for editing as it is capable of importing and editing in place without data copying Other file formats that QuickTime supports natively to varying degrees include AIFF WAV DV DIF MP3 and MPEG program stream With additional QuickTime Components it can also support ASF DivX Media Format Flash Video Matroska Ogg and many others QuickTime and MPEG 4 edit On February 11 1998 the ISO approved the QuickTime file format as the basis of the MPEG 4 file format 27 The MPEG 4 file format specification was created on the basis of the QuickTime format specification published in 2001 28 The MP4 mp4 file format was published in 2001 as the revision of the MPEG 4 Part 1 Systems specification published in 1999 ISO IEC 14496 1 2001 29 30 31 In 2003 the first version of MP4 format was revised and replaced by MPEG 4 Part 14 MP4 file format ISO IEC 14496 14 2003 32 The MP4 file format was generalized into the ISO Base Media File Format ISO IEC 14496 12 2004 which defines a general structure for time based media files It in turn is used as the basis for other multimedia file formats for example 3GP Motion JPEG 2000 33 34 35 36 37 A list of all registered extensions for ISO Base Media File Format is published on the official registration authority website www mp4ra org This registration authority for code points in MP4 Family files is Apple Computer Inc and it is named in Annex D informative in MPEG 4 Part 12 36 By 2000 MPEG 4 formats became industry standards first appearing with support in QuickTime 6 in 2002 Accordingly the MPEG 4 container is designed to capture edit archive and distribute media unlike the simple file as stream approach of MPEG 1 and MPEG 2 38 Profile support edit QuickTime 6 added limited support for MPEG 4 specifically encoding and decoding using Simple Profile SP Advanced Simple Profile ASP features like B frames were unsupported in contrast with for example encoders such as XviD or 3ivx QuickTime 7 supports the H 264 encoder and decoder 39 Container benefits edit Because both MOV and MP4 containers can use the same MPEG 4 codecs they are mostly interchangeable in a QuickTime only environment MP4 being an international standard has more support This is especially true on hardware devices such as the Sony PSP and various DVD players on the software side most DirectShow Video for Windows codec packs 40 41 include a MP4 parser but not one for MOV In QuickTime Pro s MPEG 4 Export dialog an option called Passthrough allows a clean export to MP4 without affecting the audio or video streams QuickTime 7 now supports multi channel AAC LC and HE AAC audio used for example in the high definition trailers on Apple s site 42 for both MOV and MP4 containers History editApple released the first version of QuickTime on December 2 1991 as a multimedia add on for System 6 and later The lead developer of QuickTime Bruce Leak ran the first public demonstration at the May 1991 Worldwide Developers Conference where he played Apple s famous 1984 advertisement in a window at 320 240 pixels resolution QuickTime 1 x edit The original video codecs included the Animation codec which used run length encoding and was better suited to cartoon type images with large areas of flat color the Apple Video codec also known as Road Pizza suited to normal live action video 43 the Graphics codec for 8 bit images including ones that had undergone ditheringThe first commercial project produced using QuickTime 1 0 was the CD ROM From Alice to Ocean The first publicly visible use of QuickTime was Ben amp Jerry s interactive factory tour dubbed The Rik amp Joe Show after its in house developers The Rik and Joe Show was demonstrated onstage at MacWorld in San Francisco when John Sculley announced QuickTime 44 Apple released QuickTime 1 5 for Mac OS in the latter part of 1992 This added the SuperMac developed Cinepak vector quantization video codec initially known as Compact Video It could play video at 320 240 resolution at 30 frames per second on a 25 MHz Motorola 68040 CPU It also added text tracks which allowed for captioning lyrics and other potential uses Apple contracted San Francisco Canyon Company to port QuickTime to the Windows platform 45 Version 1 0 of QuickTime for Windows provided only a subset of the full QuickTime API including only movie playback functions driven through the standard movie controller QuickTime 1 6 came out the following year Version 1 6 2 first incorporated the QuickTime PowerPlug which replaced some components with PowerPC native code when running on PowerPC Macs QuickTime 2 x edit nbsp QuickTime logo for versions 2 x and 3 x from 1994 until 1999Apple released QuickTime 2 0 for System Software 7 in June 1994 the only version never released for free It added support for music tracks which contained the equivalent of MIDI data and which could drive a sound synthesis engine built into QuickTime itself using a limited set of instrument sounds licensed from Roland or any external MIDI compatible hardware thereby producing sounds using only small amounts of movie data Following Bruce Leak s departure to Web TV the leadership of the QuickTime team was taken over by Peter Hoddie QuickTime 2 0 for Windows appeared in November 1994 under the leadership of Paul Charlton As part of the development effort for cross platform QuickTime Charlton as architect and technical lead along with ace individual contributor Michael Kellner and a small highly effective team including Keith Gurganus ported a subset of the Macintosh Toolbox to Intel and other platforms notably MIPS and SGI Unix variants as the enabling infrastructure for the QuickTime Media Layer QTML which was first demonstrated at the Apple Worldwide Developers Conference WWDC in May 1996 The QTML later became the foundation for the Carbon API which allowed legacy Macintosh applications to run on the Darwin kernel in Mac OS X citation needed The next versions 2 1 and 2 5 reverted to the previous model of giving QuickTime away for free They improved the music support and added sprite tracks which allowed the creation of complex animations with the addition of little more than the static sprite images to the size of the movie QuickTime 2 5 also fully integrated QuickTime VR 2 0 1 into QuickTime as a QuickTime extension On January 16 1997 Apple released the QuickTime MPEG Extension PPC only as an add on to QuickTime 2 5 which added software MPEG 1 playback capabilities to QuickTime Lawsuit against San Francisco Canyon edit Main article San Francisco Canyon Company In 1994 Apple filed suit against software developer San Francisco Canyon for intellectual property infringement and breach of contract 46 Apple alleged that San Francisco Canyon had helped develop Video for Windows using several hundred lines of unlicensed QuickTime source code They were contracted by Intel to help make Video for Windows better use system resources on Intel processors which was subsequently unilaterally removed 45 Microsoft and Intel were added to the lawsuit in 1995 The suit ended in a settlement in 1997 QuickTime 3 x edit The release of QuickTime 3 0 for Mac OS on March 30 1998 introduced the now standard revenue model of releasing the software for free but with additional features of the Apple provided MoviePlayer application that end users could only unlock by buying a QuickTime Pro license code Since the Pro features were the same as the existing features in QuickTime 2 5 any previous user of QuickTime could continue to use an older version of the central MoviePlayer application for the remaining lifespan of Mac OS to 2002 indeed since these additional features were limited to MoviePlayer any other QuickTime compatible application remained unaffected QuickTime 3 0 added support for graphics importer components that could read images from GIF JPEG TIFF and other file formats and video output components which served primarily to export movie data via FireWire Apple also licensed several third party technologies for inclusion in QuickTime 3 0 including the Sorenson Video codec for advanced video compression the QDesign Music codec for substantial audio compression and the complete Roland Sound Canvas instrument set and GS Format extensions for improved playback of MIDI music files It also added video effects which programmers could apply in real time to video tracks Some of these effects would even respond to mouse clicks by the user as part of the new movie interaction support known as wired movies QuickTime interactive edit During the development cycle for QuickTime 3 0 part of the engineering team was working on a more advanced version of QuickTime to be known as QuickTime interactive or QTi Although similar in concept to the wired movies feature released as part of QuickTime 3 0 QuickTime interactive was much more ambitious It allowed any QuickTime movie to be a fully interactive and programmable container for media A special track type was added that contained an interpreter for a custom programming language based on 68000 assembly language This supported a comprehensive user interaction model for mouse and keyboard event handling based in part on the AML language from the Apple Media Tool The QuickTime interactive movie was to have been the playback format for the next generation of HyperCard authoring tool Both the QuickTime interactive and the HyperCard 3 0 projects were canceled in order to concentrate engineering resources on streaming support for QuickTime 4 0 and the projects were never released to the public QuickTime 4 x edit Apple released QuickTime 4 0 on June 8 1999 47 for Mac OS 7 5 5 through 8 6 later Mac OS 9 and Windows 95 Windows 98 and Windows NT Three minor updates versions 4 0 1 4 0 2 and 4 0 3 followed 48 It introduced features that most users now consider basic 49 Graphics exporter components which could write some of the same formats that the previously introduced importers could read GIF support was omitted possibly because of the LZW patent Support for the QDesign Music 2 and MPEG 1 Layer 3 audio MP3 QuickTime 4 was the first version to support streaming It was accompanied by the release of the free QuickTime Streaming Server version 1 0 QuickTime 4 Player introduced brushed metal to the Macintosh user interface On December 17 1999 Apple provided QuickTime 4 1 this version s first major update 47 Two minor versions 4 1 1 and 4 1 2 followed 50 The most notable improvements in the 4 1 x family were 51 Support for files larger than 2 0 GB in Mac OS 9 This is a consequence of Mac OS 9 requiring the HFS Plus filesystem 52 Variable bit rate VBR support for MPEG 1 Layer 3 MP3 audio Support for Synchronized Multimedia Integration Language SMIL Introduction of AppleScript support in Mac OS The requirement of a PowerPC processor for Mac OS systems QuickTime 4 1

Version 7 0 4 released on January 10 2006 was the first universal binary version But it suffered numerous bugs including a buffer overrun which is more problematic to most users Apple dropped support for Windows 2000 with the release of QuickTime 7 2 on July 11 2007 71 The last version available for Windows 2000 7 1 6 contains numerous security vulnerabilities 72 References to this version have been removed from the QuickTime site but it can be downloaded from Apple s support section 73 Apple has not indicated that they will be providing any further security updates for older versions QuickTime 7 2 is the first version for Windows Vista Apple dropped support for Flash content in QuickTime 7 3 breaking content that relied on Flash for interactivity or animation tracks Security concerns seem to be part of the decision 74 Flash flv files can still be played in QuickTime if the free Perian plugin is added In QuickTime 7 3 a processor that supports SSE is required QuickTime 7 4

Sierra and macOS High Sierra and the default browser included on macOS Mojave released on September 24 2018 which drops support for NPAPI plug ins except for Adobe Flash dropped its support for QuickTime 7 s web plugin On September 24 2018 Apple dropped support for the macOS version of QuickTime 7 This effectively marked the end of the technology in Apple s codec and web development Starting with macOS Catalina QuickTime 7 applications image audio and video codecs will no longer be compatible with macOS or supported by Apple QuickTime X QuickTime Player v10 x edit QuickTime X pronounced QuickTime Ten 81 was initially demonstrated at WWDC on June 8 2009 and shipped with Mac OS X v10 6 82 It includes visual chapters 83 conversion sharing to YouTube video editing 84 capture of video and audio streams screen recording 85 GPU acceleration and live streaming 86 But it removed support for various widely used formats in particular the omission of MIDI caused significant inconvenience and trouble to many musicians and their potential audiences 87 In addition a screen recorder is featured which records whatever is on the screen However it is not possible to capture certain Digital rights management protected content This includes iTunes Apple TV video purchases or any content protected by Apple s FairPlay DRM technology While Safari uses FairPlay Google Chrome and Firefox use Widevine for DRM whose content is not protected from QuickTime screen capturing The reason for the jump in numbering from 7 to 10 X was to indicate a similar break with the previous versions of the product that Mac OS X indicated QuickTime X is fundamentally different from previous versions in that it is provided as a Cocoa Objective C framework and breaks compatibility with the previous QuickTime 7 C based APIs that were previously used QuickTime X was completely rewritten to implement modern audio video codecs in 64 bit QuickTime X is a combination of two technologies QuickTime Kit Framework QTKit and QuickTime X Player QTKit is used by QuickTime player to display media QuickTime X does not implement all of the functionality of the previous QuickTime as well as some of the codecs When QuickTime X attempts to operate with a 32 bit codec or perform an operation not supported by QuickTime X it will start a 32 bit helper process to perform the requested operation The website Ars Technica revealed that QuickTime X uses QuickTime 7 x via QTKit to run older codecs that have not made the transition to 64 bit 88 QuickTime X does not support SRT subtitle files 89 It has been suggested using the program Subler to interleave the MP4 and SRT files will fix this oversight which can be downloaded at Bitbucket 90 QuickTime 7 may still be required to support older formats on Snow Leopard such as QTVR interactive QuickTime movies and MIDI files In such cases a compatible version of QuickTime 7 is included on Snow Leopard installation disc and may be installed side by side with QuickTime X Users who have a Pro license for QuickTime 7 can then activate their license 91 A Snow Leopard compatible version of QuickTime 7 may also be downloaded from Apple Support website 92 The software got an increment with the release of Mavericks and as of August 2018 the current version is v10 5 It contains more sharing options email YouTube Facebook Flickr etc more export options including web export in multiple sizes and export for iPhone 4 iPad Apple TV but not Apple TV 2 It also includes a new way of fast forwarding through a video and mouse support for scrolling 93

the QTKit Framework on Mac OS 10 6 until 10 14 112 Since the release of macOS 10 15 AVKit and AVFoundation are used instead due to the removal of 32 bit audio and video codecs as well as image formats and APIs supported by QuickTime 7 Previous versions edit QuickTime consists of two major subsystems the Movie Toolbox and the Image Compression Manager The Movie Toolbox consists of a general API for handling time based data while the Image Compression Manager provides services for dealing with compressed raster data as produced by video and photo codecs Developers can use the QuickTime software development kit SDK to develop multimedia applications for Mac or Windows with the C programming language or with the Java programming language see QuickTime for Java or under Windows using COM ActiveX from a language supporting this The COM ActiveX option was introduced as part of QuickTime 7 for Windows and is intended for programmers who want to build standalone Windows applications using high level QuickTime movie playback and control with some import export and editing capabilities This is considerably easier than mastering the original QuickTime C API 113 QuickTime 7 for Mac introduced the QuickTime Kit aka QTKit a developer framework that is intended to replace previous APIs for Cocoa developers This framework is for Mac only and exists as Objective C abstractions around a subset of the C interface Mac OS X v10 5 extends QTKit to full 64 bit support The QTKit allows multiplexing between QuickTime X and QuickTime 7 behind the scenes so that the user need not worry about which version of QuickTime they need to use Bugs and vulnerabilities editQuickTime 7 4 was found to disable Adobe s video compositing program After Effects 114 115 116 This was due to the DRM built into version 7 4 since it allowed movie rentals from iTunes QuickTime 7 4 1 resolved this issue 117 Versions 4 0 through 7 3 contained a buffer overflow bug which could compromise the security of a PC using either the QuickTime Streaming Media client or the QuickTime player itself 118 The bug was fixed in version 7 3 1 QuickTime 7 5 5 and earlier are known to have a list of significant vulnerabilities that allow a remote attacker to execute arbitrary code or cause a denial of service out of bounds memory access and application crash on a targeted system The list includes six types of buffer overflow 119 120 121 122 123 124 data conversion 125 signed vs unsigned integer mismatch 126 and uninitialized memory pointer 127 QuickTime 7 6 has been found to disable Mac users ability to
