Apple QuickTime Movie (QT) is a file format that Apple developed for movie clips. It is very similar to MOV in that it is a container that can hold various types of multimedia files, including 3D and virtual reality (VR). It is an older format, whereas MOV is newer.

 

How to open a QT file?

By default, a QT file opens with QuickTime. If the QT file is Version 2.0 or earlier, then it can open with Windows Media Player, but more-recent versions will not open in this player. If unable to open a QT file with QuickTime, then use VLC media player, which works across many platforms, including mobile.

 

Since QT is an older format, it might be necessary to review the QuickTime support topics published by Apple support. Apple offers advice for opening a QT file, as well as help with movie playback.

Matroska (MKV) is a free, open-source, container standard that can hold an unlimited amount of audiovisual and multimedia files in a single file format. Since it is open source, a user can customize it with open-source software. The name derives from “Matryoshka” dolls, which is a famous type of Russian handicraft that consists of a set of wooden dolls of decreasing size nested one inside another.

 

How to open an MKV file?

The best way to open an MKV file is to use VLC media player. This media player is compatible with all operating systems and platforms. This is important because MKV is not an industry standard, which means that other media players might not support it.

 

Additionally, MKV does not use codecs to compress file size, which means the file can be quite large. Therefore, another option for opening an MKV file is to download the appropriate codecs that are compatible with the selected media player. To accomplish this, download the Combined Community Codec Pack (CCCP) from a trusted site, such as Ninite.
