MOV is one of the most common multimedia file formats. It was developed by Apple Computer, compatible with Macintosh and Windows platforms. It was first used actively in the early 1990s after Apple launched its QuickTime Media Player, so it’s sometimes called QuickTime. At first, it was a unique format for audio and video data, but later its competitors such as AVI, AMV, FLV, Real Media appeared. MOV files are currently standard for storing movies and any other video.
3G2 is an audio / video format that was developed using the 3rd Generation Partnership Project 2 (3GPP2). The file extension is an improved version of the 3GP format. Today it is already outdated, despite the fact that it was previously updated. As a result of the implementation of the 3rd Generation Partnership Project, standards were developed that relate to methods of transmitting a wide variety of media data. For example, on mobile networks. The development of such standards, in particular, has led to the introduction of the 3G2 format and to the use of various types of media data on the global network for online streaming. This type of file is most often used on mobile phones, as well as on phones that support 3G. 3G2 video files can also be played on many computers. We emphasize that in this case there may be a need for additional applications. The 3G2 format is very similar to the MPEG-4 Part 14 series (MP4) format. However, in comparison with it, the 3G2 format is not so complicated. When you apply this type of file, you need to consider the possibility of reducing the requirements for the width of both the information transfer channel and disk space. So, the format for mobile phones is exactly what you need. 3G2 files have been specifically developed for phones operating in the CDMA standard.
