1 - Not a video format, but a file container. The container is an open standard that relies on often proprietary codecs to deliver audio and video. Released originally in 1991 for the Macintosh, the underlying container hasn't changed much from its original specifications. This is essential, however - for the backwards compatibility that the platform delivers is unmatched by any other multimedia platform, except for perhaps Xiph.org's Ogg container.

Quicktime is typically known for its proprietary codecs as of Quicktime 3.0 or later which have been used to deliver audio and video over the Internet. Not known for top-notch streaming quality, the platform since 1999 has more or less been used to deliver progressive-download movies. Such as those found on ign64.ign.com ; the archived IGN Nintendo 64 news website.

Critics would argue that the platform is bloated, although no spyware or malware is distributed. A stand-alone installer is available for those that do not want iTunes, although iTunes is dependent upon the platform. Most of the proprietary codecs have been reverse-engineered, allowing playback in such players as VLC. Recently, Apple has moved away from standards such as Sorenson Video and qDesign music to insist on somewhat of a truly compatible model ; as supposed by the heavily patented MPEG-4 standard.

Quicktime directly competed with Real Network's real audio / video standard, Microsoft Windows Media, and Xiph's Ogg multimedia platform.
1- Quicktime is a container, not a video type.
2 - Quicktime sucks! It's so bloated! Yeah, if you try playing back high-res AVC on a Northwood...
3 - Major media outlets use Quicktime to fight off the invasion of the rather sucky Windows Media Video format.
4 - Quicktime is nice, but Theora is more useful for video despite its aging video portion..

A lousy bloatware audio/video codec and software package created by Apple.
Hrm, I need another plugin?
Gah! Fuck QuickTime!

A mediocre at best video format that was never the best video format even in the early days when Apple would have had you think otherwise. Generally known for producing lousy grainy video streams on the internet.
Quicktime is an apple product and it shows!

A pointless program made to run movies. Annoys the fucking hell out of you when you accidentally click on it.
Oh shit, this video needs quicktime. Fuck that

A video format from Apple with the shittiest and gayest SDK I have ever seen, and even worse documentation. Includes such revealing function names as MoviesTask(), and short, easy to type constant names as kQTMovieAudioExtractionPropertyID _AudioStreamBasicDescription. Actually has a constant called DoTheRightThing, and calls setting things up "preflighting". I can just picture Quicktime engineers sitting in their turtleneck sweaters thinking that using words like "preflight" somehow makes them cool. Having spent some time with the Quicktime APIs I think I can safely assume that general Mac development is just as retarded.
Dude, I have been trying to find what numerical value kQTAnnoyingLongAssConstantNames _IDontHaveTwentyFingersToTypeThisShit maps to in the Quicktime header files, but haven't had any luck so far.

A gay-ass media player that you have to install in order to hear the audio on YTMND in Firefox. Also installs stupid iTunes with it.
Quicktime is so gay it's gay.

An annoying virus program.



"Did you just download Quicktime?"
"Oh shit... you just ruined your videos."

Awful media player by Apple which is usually installed by people only because they need it to run a .MOV file, Apple's shitty proprietary video format. Constantly freezes or lags out on older computers and laptops, and has the ugliest, most unintuitive GUI ever. Has features that require a paid PRO license which are free in other programs, such as video conversion. Has absolutely no support at all for the Windows version. It leaves behind various malware such as Apple Application Support and Apple Software Update when uninstalled.
If you're planning to install QuickTime, you might as well use Windows Media Player.
