MJPEG vs. H.264

By: John Honovich, Published on Apr 17, 2009

Recently, IQinVision releaed an article advocating benefits of MJPEG [link no longer available].

[Update Dec 2010: We conducted extensive testing comparing MJPEG and H.264. Read our Test Results of MJPEG vs H.264.]

While I found the article technically accurate, well written and worth reading, the nature of the application and its economics demand that MJPEG be almost always avoided. Since H.264 is hot right now, this is a popular claim to make. However, a discussion of this can help examine the economics and operational drivers driving this interest.

Jason's central claims are:

1. With moving cameras or images of high activity areas, MPEG4 and H.264 provide little bandwidth savings relative to MJPEG.

2. Proper network design requires factoring in worse case scenarios so you will need to dedicate the same amount of bandwidth whether or not you use MJPEG, MPEG4 or H.264.

3. MJPEG provides higher quality because of no intra-frame compression.
