What are the advantages/disadvantages of MPEG4 video encoding versus MJPEG video encoding?
The video sequencing compression that is used my MPEG4 allows it to use less network bandwidth and storage that MJPEG. MPEG4 videos generally have a slightly lower image quality when compared directly to an MJPEG video. This is not very noticeable when viewing but is more important if video images need to be edited, which is normally not applicable in surveillance video. MJPEG and MJPEG2000 capture a stream of individual JPEG images while MPEG4 captures changes to images to create video.
