Motion JPEG 2000 (MJ2 or MJP2) is a file format for motion sequences of JPEG 2000 images and associated audio, based on the MP4 and QuickTime format. Filename extensions for Motion JPEG 2000 video files are .mj2 and .mjp2 , as defined in RFC 3745.
JPEG 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), [1] with the intention of superseding their original JPEG standard (created in 1992), which is based on a discrete cosine transform (DCT), with a newly designed, wavelet-based method.
Motion JPEG 2000 also defined a container format based on the ISO base media file format - MJ2. M2TS was not defined by MPEG, but Blu-ray Disc Association. M2V is a filename extension, not a typical container format - there is no information about "M2V" in the ISO/IEC 13818-1 (MPEG-2 Systems) specification.
M-JPEG is an intraframe-only compression scheme (compared with the more computationally intensive technique of interframe prediction).Whereas modern interframe video formats, such as MPEG1, MPEG2 and H.264/MPEG-4 AVC, achieve real-world compression ratios of 1:50 or better, M-JPEG's lack of interframe prediction limits its efficiency to 1:20 or lower, depending on the tolerance to spatial ...
JPEG is a format for compressed digital images. JPEG may also refer to: Joint Photographic Experts Group, the standardization group after which the JPEG coding format is named; Motion JPEG, a video compression method using JPEG still image compression, sometimes referred to as "JPEG"
The International Organization for Standardization approved the QuickTime file format as the basis of the MPEG-4 file format. The MPEG-4 file format specification was created on the basis of the QuickTime format specification published in 2001. [13]

It is used as the basis for other file formats in the family such as MP4, 3GP, and Motion JPEG 2000). [8] Historically, the text was also published as ISO/IEC 15444-12 (JPEG 2000 Part 12), although the JPEG 2000 version of the standard was withdrawn in January 2017 since it was redundant with the MPEG-4 publication.
