MOV file open in Apple QuickTime Player X
MOV files may contain video, audio, timecode, and text tracks, which can be used to store and synchronize different types of media. Each media track may be encoded using one of several different codecs. In order to play a MOV file, an application must be able to recognize the specific codec(s) used in the file.
You can convert MOV files to more standard media file formats with various media applications. For example, VLC media player allows you to convert a MOV video to an .MP4 file or a MOV audio file to the .OGG format.
NOTE: MOV and MP4 files are similar and can both be played by QuickTime. However, MP4 files are recognized as an international standard and are more widely supported than MOV files.
