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.
