mov is usually the format of video type computer files.
MOV is QuickTime packaging format (also called movie format). It is an audio and video file packaging developed by Apple and is used to store common digital media types. When QuickTime (*.mov) is selected as "Save Type", animations will be saved as ·mov files. QuickTime is used to save audio and video information, and is supported by all mainstream computer platforms including Apple Mac OS, Microsoft Windows 95/98/NT/2003/XP/VISTA, and even WINDOWS7.
The QuickTime file format supports 25-bit color, supports leading integrated compression technology, provides more than 150 video effects, and is equipped with a sound device that provides more than 200 MIDI compatible speakers and devices. It is an excellent video encoding format whether it is played locally or spread online as a video streaming format.
MOV format files are organized in the form of tracks. A MOV format file structure can contain many tracks. There are some empirical limits on the number of tracks, and these values will change as computers become more powerful. However, the MOV format file itself does not have a predefined limit on the number of tracks.
The relationship between MOV format files and their tracks, as well as the time ratios of different media, defines the time coordinate system of MOV format files.
MOV format files have a current time, which is used to indicate the part of the MOV format file that is about to be displayed. The current time is expressed in MOV format file time scale units. For example, if the time scale of the MOV format file is 600 and it has been played for half a second, the current time is 300.
The current time can range from 0 to the duration of the MOV format file. It changes continuously as the MOV format file is played. Dragging the play arrow of the MOV format file controller will also change the current time of the movie.
MOV format files also have the concept of rate. When the MOV format file stops, this value is 0. When the MOV format file is played at normal speed, it is 1. The normal playback speed is determined by the time ratio of the MOV format file. to make sure. For example, when the playback rate is 1, a movie with a time scale of 600 plays at a speed of 600 time units per second. A negative rate causes the movie to play backwards. A rate greater than 1 will cause MOV format files to play faster than normal, and a rate less than 1 will cause movies to play slower than normal. For another example, when the playback rate is 0.5, a MOV format file with a time ratio of 600 is played at a speed of 300 time units per second; if the playback rate is 2, a file in the MOV format is played at a speed of 1200 time units per second. Play.
