[Wiki] Motion JPEG

Motion JPEG, also known as MJPEG, is a video codec which saves every single frame as jpeg image.
In contrary to videos which are comprimized with MPEG codecs where, among other things, only the frame differences are stored, in MJPEG videos the whole frames are saved as separately jpeg images.  This brings advantages as also disadvantages with it.
On the one hand there are no artefacts in fast video sequences/scenes but on the other hand you get much larger video files because much more image information has to be stored. For a video in SVHS-quality, which is saved in MJPEG format, you need round about 25 MBit (3,1 MByte) per second.
MJPEG encoded video material can be found today usually only in the ip-cam sector.  (ip-cam = network camera) For network cameras the MJPEG codec seems to be ideal, because it needs hardly any hardware resources for encoding the video and nearly every […]
