Editing QuickTime (section)

== History ==
Apple released the first version of QuickTime on December 2, 1991, as a [[multimedia]] add-on for [[System Software 6|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)|1984 advertisement]] in a window at 320×240 pixels resolution.

=== QuickTime 1.x ===
The original video [[codec]]s 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.<ref>[http://wiki.multimedia.cx/index.php?title=Apple_RPZA Apple RPZA - MultimediaWiki]. wiki.multimedia.cx (December 11, 2008). Retrieved on August 23, 2013.</ref>
* the [[QuickTime Graphics|Graphics]] codec, for 8-bit images, including ones that had undergone [[dithering]]

The first commercial project produced using QuickTime 1.0 was the CD-ROM [https://web.archive.org/web/20070607104108/http://www.againstallodds.com/alice.htm From Alice to Ocean]. 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.<ref>{{cite web|url=http://www.maclife.com/article/feature/complete_history_macworld_expo?page=0,1 |title=The Complete History of the Macworld Expo |access-date=August 2, 2013 |url-status=unfit |archive-url=https://web.archive.org/web/20140804220227/http://www.maclife.com/article/feature/complete_history_macworld_expo?page=0,1 |archive-date=August 4, 2014 }}</ref>

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.<ref name="Apple: The Inside Story">{{Cite book |last=Carlton |first=Jim |date=1997 |title=Apple: The inside story of intrigue, egomania, and business blunders |location=New York |publisher=Random House |page=[https://archive.org/details/appleinsidestory00carl/page/309 309] |isbn=0-8129-2851-2 |url-access=registration |url=https://archive.org/details/appleinsidestory00carl/page/309 }}</ref> 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 ===
[[File:Quicktime old logo.svg|thumb|200px|QuickTime logo for versions 2.x and 3.x, from 1994 until 1999]]
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 Corporation|Roland]]), or any external MIDI-compatible hardware, thereby producing sounds using only small amounts of movie data.

Following [[Bruce Leak]]'s departure to [[MSN TV|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 (technologist)|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|date=October 2013}}

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 (computer science)|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 ===
{{Main|San Francisco Canyon Company}}
In 1994, Apple filed suit against software developer [[San Francisco Canyon Company|San Francisco Canyon]] for intellectual property infringement and breach of contract.<ref>{{Cite news|url=https://www.nytimes.com/1994/12/12/business/apple-lawsuit-may-renew-legal-battle-with-microsoft.html|title=Apple Lawsuit May Renew Legal Battle With Microsoft|last=Markoff|first=John|date=1994-12-12|newspaper=The New York Times|issn=0362-4331|access-date=2016-04-15}}</ref> 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.<ref name="Apple: The Inside Story"/> Microsoft and Intel were added to the lawsuit in 1995. The suit ended in a settlement in 1997.

=== QuickTime 3.x ===
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 [[interactivity|interaction]] support (known as '''wired movies''').

==== QuickTime interactive ====
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 ===
Apple released QuickTime 4.0 on June 8, 1999<ref name="Timeline of QuickTime Updates">{{cite web | title=Timeline of QuickTime Updates at the Apple Museum | url=http://www.theapplemuseum.com/index.php?id=41 | access-date=January 8, 2007}}</ref> 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.<ref>{{cite web | title=Apple&nbsp;– Developer&nbsp;– QuickTime&nbsp;– Technical Note TN1183 | url=https://developer.apple.com/technotes/tn/tn1183.html | access-date=January 8, 2007}}</ref>
It introduced features that most users now consider basic:<ref>{{cite web | title=Apple&nbsp;– Developer&nbsp;– QuickTime&nbsp;– What's New in QuickTime | url=https://developer.apple.com/documentation/QuickTime/whatsnew.htm | access-date=January 8, 2007}}</ref>

* 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 [[Lempel–Ziv–Welch#Patents|LZW patent]].)
* Support for the QDesign Music 2 and MPEG-1 Layer 3 audio (MP3). 
* QuickTime 4 was the first version to support [[Streaming media|streaming]].  It was accompanied by the release of the free [[QuickTime Streaming Server]] version 1.0.
* QuickTime 4 Player introduced [[brushed metal (interface)|brushed metal]] to the Macintosh user interface.

On December 17, 1999, Apple provided QuickTime 4.1, this version's first major update.<ref name="Timeline of QuickTime Updates" />  Two minor versions (4.1.1 and 4.1.2) followed.<ref>{{cite web | title=Apple&nbsp;– Developer&nbsp;– QuickTime&nbsp;– Technical Note TN1197 | url=https://developer.apple.com/technotes/tn/tn1197.html | access-date=January 8, 2007}}</ref> The most notable improvements in the 4.1.x family were:<ref>{{cite web | title=Apple&nbsp;– Developer&nbsp;– QuickTime&nbsp;– Summary of Changes and Enhancements for QuickTime 4.1 | url=https://developer.apple.com/documentation/QuickTime/REF/QT41_HTML/QT41WhatsNew-2.html
 | access-date=January 8, 2007}}</ref>

* Support for files larger than 2.0 [[gigabytes|GB]] in Mac OS 9. (This is a consequence of Mac OS 9 requiring the [[HFS Plus]] filesystem.<ref>{{Cite web|title=Mac OS 8, 9: Mac OS Extended Format - Volume and File Limits|url=https://support.apple.com/kb/TA21924?locale=en_US|access-date=2020-06-09|website=support.apple.com}}</ref>)

* 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 ===
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.<ref>{{cite web | title=Timeline of QuickTime Updates at the Apple Museum | url=http://www.theapplemuseum.com/index.php?id=41 | access-date=January 6, 2007 |url-status=dead |archive-url=https://web.archive.org/web/20111130002506/http://www.theapplemuseum.com/index.php?id=41 |archive-date=November 30, 2011 }}</ref> Three more updates to QuickTime 5 (versions 5.0.2, 5.0.4, and 5.0.5) were released over its short lifespan.

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 X (pronounced ''QuickTime Ten'')<ref>{{cite web|url=http://www.roughlydrafted.com/2008/06/12/wwdc-2008-new-in-mac-os-x-snow-leopard/|title=WWDC 2008: New in Mac OS X Snow Leopard|access-date=August 15, 2015|archive-date=October 17, 2008|archive-url=https://web.archive.org/web/20081017052319/http://www.roughlydrafted.com/2008/06/12/wwdc-2008-new-in-mac-os-x-snow-leopard/|url-status=dead}}</ref> was initially demonstrated at [[WWDC]] on June 8, 2009, and shipped with [[Mac OS X Snow Leopard|Mac OS X v10.6]].<ref>{{cite web|url=http://www.tuaw.com/2009/06/08/quicktime-x-leaps-forward-in-snow-leopard/|title=QuickTime X leaps forward in Snow Leopard|author=Victor Agreda Jr.|work=Engadget|access-date=August 15, 2015|archive-date=January 31, 2015|archive-url=https://web.archive.org/web/20150131141531/http://www.tuaw.com/2009/06/08/quicktime-x-leaps-forward-in-snow-leopard/|url-status=dead}}</ref>

It includes visual chapters,<ref>thumbnail images for chapters instead of only text</ref> conversion, sharing to YouTube, video editing,<ref>trimming through a frame-based timeline akin to iMovie's</ref> capture of video and audio streams, screen recording,<ref>allowing basic screencasting built-in</ref> GPU acceleration, and live streaming.<ref>[https://www.apple.com/macosx/refinements/enhancements-refinements.html#quicktime OSX Leopard enhancements: QuickTime X] {{webarchive |url=https://web.archive.org/web/20140820232918/https://www.apple.com/macosx/refinements/enhancements-refinements.html#quicktime |date=August 20, 2014 }}</ref>

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.<ref>{{cite web | title=No MIDI Instruments in Quicktime X | url=http://www.sibelius.com/cgi-bin/helpcenter/chat/chat.pl?com=thread&start=460345&groupid=3&&guest=1#460345 | access-date=April 7, 2014}}</ref>

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.<ref>{{cite web | title=Mac OS X 10.6 Snow Leopard: the Ars Technica review QuickTime X | date=September 2009 | url=https://arstechnica.com/apple/reviews/2009/08/mac-os-x-10-6.ars/6 | access-date=September 29, 2009}}</ref>

QuickTime X does not support .SRT subtitle files.<ref>{{cite web | title=QuickTime X can't use .srt files | url=https://apple.stackexchange.com/questions/44406/quicktime-x-cant-use-srt-files?rq=1 |work=Ask Different| access-date=August 8, 2019}}</ref> 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]].<ref>{{cite web | title=Subler Downloads | url=https://bitbucket.org/galad87/subler/downloads|work=Bitbucket.org |access-date=August 8, 2019}}</ref>

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.<ref>{{cite web

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.<ref>{{Cite news|url=https://support.apple.com/en-us/HT201066|title=How to use QuickTime Player|work=Apple Support|access-date=2018-05-26|language=en-US}}</ref>

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.
