The m-jpeg stands for Motion JPEG. M-JPEG is a video format that uses JPEG picture compression in each video frame. Frames of the video don't interact with each other in any way (like they do in MPEG-1, MPEG-2, etc.), resulting in much bigger filesize. Still, on the other hand, it makes video editing easier because each of the frames has all of the information they need stored in them.
M-JPEG is used in very high-quality video captures—normally as the raw data format, which is edited and compressed into another format after the editing process is completed. Unfortunately, M-JPEG is not a standard or even standardized. Each vendor has its own codecs, and normally, M-JPEG files created with one codec cannot be read with other vendors' codecs.
M-JPEG is recommended for use in the video capture process as a raw data format. Editing this video stream is extremely easy, and encoding the edited M-JPEG stream into the final format (such as MPEG-1, MPEG-2, or Divx) normally gives the best possible video quality.
