Most other codecs are proprietary. Some have compliancy issues and several limitations to support any video formats or resolutions. (See Table 2.) The MPEG family is ideal for last-mile content delivery to viewers, but not for production and storage, since pictures have to be post-processed.
JPEG 2000 has gained significant attraction as a mezzanine format. Open and well-documented, the codec is future-proof and extendable. That said, it is not surprising that the Library of Congress, France’s Institut National de l’Audiovisuel and several Hollywood studios, such as 20th Century Fox, have selected the codec for storage and preservation.
JPEG 2000 is a codec like no others. It gives users a superior quality, control and a unique ﬂexibility of the image processing chain. The growing use of JPEG 2000 to archive and create mezzanine files, and the ongoing standardization process of the IMF based on JPEG 2000, are just a few of its advantages.
