About Motion JPEG
MJPEG (M-JPEG) is the name of multimedia formats where each video frame or interlaced field of a digital video sequence is separately compressed as a JPEG image. It is often used in mobile appliances such as digital cameras.
M-JPEG uses intraframe coding technology that is very similar to the I-frame part of video coding standards such as MPEG-1 and MPEG-2, but doesn't use interframe prediction. This results in a loss of compression capability, but eases video editing, since simple edits can be performed at any frame when all frames are I-frames. MJPEG is frequently used in non-linear video editing systems. Reproduction of this format at full speed requires fast JPEG decoding capability. |
