Question: is mjpeg the same as mpeg?
Answer: MPEG and MJPEG, what is the difference in quality. I'd say from that, MPEG will obviously use more compression but be more difficult to edit. MJPEG can potentially be lossless "2:1 MJPEG compression is lossless" (though my guess is that's in terms of loss between frames as each frame is still a JPEG frame).
