MJPEG is a format of multimedia data, which uses a frame-by-frame video track compression technology JPEG. This codec does not encode the difference (movement) between frames, whereby the image in some places does not turn out smooth enough. The main advantage of this format is the low requirements to hardware computational power, which, in turn, leads to a low level of compression and a larger resulting file size. It is actively used in web and IP-cameras.

3G2 is an audio and video format developed by Third Generation Partnership Project for CDMA-based (Code Division Multiple Access) phones. Actually it is an updated version of the 3GP file extension. Both formats are based on the ISO base media file format that facilitates presentation and interchange of the media. The 3G2 format is flexible and requires little storage space that is why it is mostly used by cell phones for saving files. However 3G2 movies can be played on computers but in some cases additional applications may be needed.
