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.

MPG is an extension used for files compressed with MPEG-1 or MPEG-2 standard. MPG files can be played on Windows, Mac and any mobile devices. The first versions of this format were significantly limited, supporting low video resolution and limiting data bandwidth, but latest standard updates allows it to be used even in HDTV broadcasting.
