MPEG4 = MPEG4 is a newer codec and supports 3D content, low bit rate encoding, and support for Digital Rights Management, which controls the use of copyrighted digital work. MPEG4 is used for web-streaming media, broadcast television, videophones, and CD distribution. MPEG4 is widely used in video surveillance, and has recently been improved to the AVC standard. As the two formats, MJPEG and MPEG4, usually target different applications, MPEG4 is not expected to replace MJPEG. MJPEG is recommended for surveillance applications and recording, thanks to its ease of use, wide compatibility and high image quality. MPEG4 is recommended for live viewing and for applications where bandwidth and storage limitations are important factors.
