Motion JPEG, also known as M-JPEG, is a video file format consisting of a sequence of individual JPEGimages; unlike other video compressionalgorithms, each frame is an image unto itself. It is often used by video disc jockeys and multimedia artists. A video file format is a standard for encoding digital video, audio and some auxiliary information into a file. ...

M-JPEG is normally used in HTTPstreams by using the multipart/x-mixed-replace content type which separates each image into individual HTTP replies separated by an agreed marker.

There is no standard file format for Motion JPEG which can make storing and handling the format difficult.
MotionJPEG (M-JPEG) is an informal name for multimedia formats where each video frame or interlaced field of a digital video sequence is separately compressed as a JPEGimage.
Unlike the video formats specified in international standards such as MPEG-2 and the format specified in the JPEG still-picture coding standard, there is no document that defines a single exact format that is universally recognized as a complete specification of "MotionJPEG" for use in all contexts.
MotionJPEG uses intraframe coding technology that is very similar in technology to the I-frame part of video coding standards such as MPEG-1 and MPEG-2, but does not use interframe prediction.
JPEG provides for lossy compression of images (although there are variations on the standard baseline JPEG which are lossless).
The JPEG committee investigated the patent claims in 2002 and were of the opinion that they were invalidated by prior art.
The JPEG committee has as one of its explicit goals that their standards (in particular their baseline methods) be implementable without payment of license fees, and they have secured appropriate license rights for their upcoming JPEG 2000 standard from over 20 large organizations.
