Mov is usually a video-type computer file format.

MOV is QuickTime encapsulation format (also called movie format), which is an audio and video file encapsulation developed by Apple Company for storing common digital media types. When QuickTime (*.mov) is selected as Save Type, the animation is saved as a. mov file. QuickTime is used to save audio and video information and is supported on all major computer platforms including Apple Mac OS, Microsoft Windows 95/98/NT/2003/XP/VISTA, and even Windows 7.

QuickTime file formats support 25-bit color, support leading integrated compression technologies, provide more than 150 video effects, and come with sound devices that provide more than 200 MIDI compatible audio and devices. It is an excellent video encoding format whether it is played locally or distributed as a video streaming format on the Internet.

MOV files are organized in the form of tracks. A MOV file structure can contain many tracks. There are some empirical values for the number of tracks, which change as computers become more powerful, however MOV files themselves do not have a predefined limit on the number of tracks.

The relationship between MOV files and their tracks, as well as the time scale of different media, defines the time coordinate system of MOV files.

MOV files have a current time that indicates the portion of the MOV file that is about to be displayed. The current time is expressed in MOV file time scale units. For example, if the MOV format file has a time scale of 600 and has been playing for half a second, the current time is 300.

The current time can range from 0 to the length of the MOV file. It constantly changes with the playback of MOV format files. Dragging the MOV file controller's play arrow will also change the movie's current time.

MOV files also have a rate concept, this value is 0 when MOV files stop, 1 when MOV files play at normal speed, the normal playback speed is determined by the time ratio of MOV files. For example, when the playback rate is 1, a movie with a time scale of 600 plays at 600 time units per second. A negative ratio will cause the movie to play backwards. A ratio greater than 1 causes MOV files to play faster than normal, and less than 1 causes movies to play slower than normal. As another example, a MOV file with a time scale of 600 plays at 300 time units per second at a playback rate of 0.5 and at 1200 time units per second at a playback rate of 2.
