What is MPEG4 video encoding?
The Motion Picture Experts Group (MPEG) released MPEG-4 encoding in 1998. The basic idea behind MPEG is that compressed images are compared before being transmitted over the network. The first compressed image is used as a reference and compared to the images that follow it in the video sequence. The first image is transmitted over the network along with the parts of the following images that differ from the initial reference image. The viewing application on the receiving end of the transmission then reconstructs all images based on this information and displays the result. This is a simplified description of how MPEG-4 works.
What is MJPEG video encoding?
Motion JPEG (MJPEG) is a video encoding where each frame of video is captured and compressed into a separate JPEG image. The resulting quality of video compression is independent from the motion in the image.
What is MJPEG2000 video encoding?
MJPEG2000 or MJ2K is an adaptation of the JPEG2000 standard used for still photos. MJPEG2000 treats a video stream as a series of still photos, compressing each individually, and with no interframe compression. Because no interframe compression is used, it is ideal for editing. The JPEG2000 standard is the offical successor to JPEG and will eventually replace the older JPEG standard for high-quality image compression.
