Motion JPEG

M-JPEG

(Motion-JPEG) Before the MPEG moving picture format became a standard, several Motion JPEG formats were created to tie consecutive JPEG still frames together. Motion JPEG does not use interframe compression as does MPEG and is therefore easier to edit (see interframe coding). For compatibility, video editors may support one of the Motion JPEG methods. For faster editing, MPEG can also be encoded without interframe compression. See MPEG.

The cameras let users capture 4K movies without crop, and the 4K footage is recorded in motion JPEG. The cameras allows for frame grabs, that is, users can review footage and at any given point, extract a moment from the video and save it as a high-quality 8MP JPEG on the camera.
According to the Library of Congress, Motion JPEG (M-JPEG) is a legacy format worth saving, because so many still images are stored in the JPEG compression format, and M-JPEG is essentially a restricted JPEG with a fixed YCbCr color-space, encoded at 4:2:2, and using basic Huffman encoding rather than arithmetic or progressive encoding.
The Photon Series IP cameras can capture 1280 x 720p HD JPEG images or record H.264/MPEG-4 and motion JPEG video clips at 30 frames per second to document insurance claims or provide video evidence.
The advantages of motion JPEG are equivalent with single still JPEG pictures i.e.
The EOS 1D-C captures 4K video using 8-bit motion JPEG
Multiple streams in H.264 and Motion JPEG can be sent simultaneously.
Multiple H.264, Motion JPEG and MPEG-4 streams simultaneous allows systems to be optimized for both image quality and bandwidth-efficiency.
While the former entails a 1280 x 720 pixel resolution, progressive scan, HDTVcolourfidelity, full frame rate and a 16:9 format the latter can deliver multiple, individually configurable H.264 and Motion JPEG video streams simultaneously.
AXIS M50 cameras can deliver multiple, individually configurable H.264 and Motion JPEG video streams simultaneously
The AVCHD format almost doubles the recording time in HD quality, when compared with the conventional Motion JPEG. The LUMIX FX78 also boasts Dolby[R] Digital Creator to record high quality audio.
