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.

HEVC or h.265 is the most advanced codec for now because it has the lowest bitrate without losing the image quality. The codec has three main features that distinguishes it from others: parallel decoding, random access to images within the video stream and larger maximum block size. HEVC is aimed to offer the same level of video quality as AVC (h.264), but with improved compression, that is why a video file compressed with the codec will be twice smaller.
