MJPEG vs H.264

MJPEG vs H.264

In multimedia, MJPEG, aka Motion JPEG or M-JPEG is a video compression format in which each video frame or interlaced field of a digital video sequence is compressed separately as a JPEG image. MJPEG format is widely applied to closed circuit TVs, digital recorders, web cameras, and non-linear video editing system. As a historical encoder, it shares good compatibility with some MJPEG players, browsers and even game consoles. And MJPEG encoded videos are commonly saved in .mjpeg, .mjpg, .avi or .mov container format.


MJPEG or H.264, which one to choose? Compared with H.264, MJPEG takes a very different approach to video compression. H.264 compresses a video as a whole while MJPEG compresses a video by its single frame and interlaced field. MJPEG does pretty well in output quality, but as for end-users, they can even hardly notice the differences in the video quality with their naked eyes.

The defects that MJPEG brings are easy to see as well - low compression ratio, huge bandwidth and storage occupation. In one word, whether to choose MJPEG encoder or H.264 mainly depends on what users want. As for closed circuit television, HD video recording and editing, MJPEG will obviously have a better performance. But as for regular video editing, transmission, sharing and playback which do not ask for an output of extremely high quality, H.264 is definitely your best choice!
