QT 파일이란 무엇인가요?
A QT file is a movie file saved in the QuickTime File Format (QTFF), a multimedia container format developed by Apple. It contains one or more audio, video, or text (subtitle) tracks and typically uses the MPEG-4 codec for compression. QT files most often store movies and video clips.
추가 정보
In 1991, Apple released QTFF, which eventually led to the formation of the MPEG-4 standard. Apple designed QTFF to support various media types to accommodate the transfer of multimedia between applications, operating systems, and devices.
Video files saved in QTFF may use the .qt or .mov file extensions but .MOV files are much more common than QT files. Since MOV and QT files often store video compressed with the MPEG-4 codec, they are commonly interchanged with .MP4 video files.
More information about the QuickTime File Format
QTFF is object-oriented and forward-compatible, allowing it to support new object types introduced over time. In addition, the format supports media data, which is the video, audio, or text data, and metadata. The metadata includes the media compression utilized, timing information, the number of media tracks, and an index of the media data location.
QT 파일을 여는 방법

You can also play QT files in Android and iOS with VLC for Android and VLC for iOS.
