QuickTime

Japanese: QuickTime - くいっくたいむ
QuickTime

A multimedia technology developed by Apple Inc. in the United States. It can handle videos, music, animations, documents, still images, etc. in an integrated manner. QuickTime files have the extension .mov or .qt, but it can also be used to play a variety of other file formats, including videos (AVI, DV, MPEG-4), audio (WAVE, MIDI, MP3), and still images (JPEG, BMP). There is also QuickTime VR, which allows you to watch 3D images.

Released in 1991, it was initially only compatible with Apple's Macintosh (Mac) operating system, but has since become available for other operating systems such as Windows and Linux. Playback is done with QuickTime Player, an application provided free of charge by Apple. If editing or saving is required, QuickTime Pro is available for a fee. QuickTime X was newly developed for MacOS X Snow Leopard and later operating systems, and is a different application from the existing QuickTime that cannot be used with older MacOS or Windows.

Japanese:

アメリカのアップル社が開発したマルチメディア技術。動画、音楽、アニメーション、文書、静止画などを統合的に扱うことができる。QuickTimeのファイルは拡張子が.movまたは.qtになるが、それ以外にも、動画(AVI、DV、MPEG-4)、音声(WAVE、MIDI、MP3)、静止画(JPEG、BMP)などのさまざまな形式のファイルの再生を中心に利用することができる。また、三次元映像を視聴できるQuickTime VRもある。

 1991年に発表され、当初は、アップルのマッキントッシュ(Mac)用OSだけに対応していたが、その後、WindowsやLinuxなど他のOSでも利用できるようになった。再生は、アップルが無償で提供しているアプリケーションのQuickTime Playerで行う。また、編集や保存が必要な場合は、有償のQuickTime Proを利用することになる。なお、QuickTime Xは、MacOS X Snow Leopard以降のOS向けに新たに開発されたもので、旧MacOSやWindowsでは利用できない、既存のQuickTimeとは別のアプリケーションである。
