Motion JPEG

In multimedia, Motion JPEG (M-JPEG or MJPEG) is a video compression format in which each video frame or interlaced field of a digital video sequence is compressed separately as a JPEG image. Originally developed for multimedia PC applications, M-JPEG is now used by video-capture devices such as digital cameras, IP cameras, and webcams; and by non-linear video editing systems. It is natively supported by the QuickTime Player, the PlayStation console, and web browsers such as Safari, Google Chrome, Mozilla Firefox and Microsoft Edge.

MJPEG was first used by the QuickTime Player in the mid 1990s.

Software and devices using the M-JPEG standard include web browsers, media players, game consoles, digital cameras, IP cameras, webcams, streaming servers, video cameras, and non-linear video editors.

M-JPEG is frequently used in non-linear video editing systems. Modern desktop CPUs are powerful enough to work with high-definition video so no special hardware is required and they in turn offer native random-access to a frame, M-JPEG support is also widespread in video-capture and editing equipment.

The PlayStation game console integrated M-JPEG decompression hardware for in-game FMV sequences while the PlayStation Portable handheld game console can play M-JPEG from the Memory Stick Pro Duo under the .avi extension with a resolution of 480×272. Both can record clips in M-JPEG via its Go!Cam camera.
