Open QT File

The QT file extension and format is used for files related to the QuickTime program, hence the acronym QT.

QT files basically contain movies, and these QT files, too, can contain various media, including videos, graphics, animations, and even movies.

Normally these QT files are compressed due to their size, thus, the compression significantly facilitates the transfer and distribution of the files and the reduced size also facilitates their transmission online.

The design of the QT file format is a container that includes multiple types of multimedia tracks, that can include video, audio, subtitles, or other types of effects.

A very particular feature is the flexibility to separate the different tracks, which makes QuickTime especially popular as an editor.

QT is an extension used by QuickTime, however, the MOV file extension is much more popular, therefore, QuickTime movies are more commonly saved in MOV format than with the QT extension.
