M2V is a format containing only video data, audio is stored in other accompanied file. The extension is widely used in DVDs and video compression systems. Actually it is an MPEG-2 video stream. M2V is also used in digital TV where serves as a standard that defines the structure of transport streams and data transmission methods.

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.
