An overview of the commonly used video formats, from AVI and MOV to MPEG, compression methods and an explanation of MPEG encoding with an example. The attainable image quality of an encoded MPEG video depends mostly on the quality of the encoder. However, the attainable encoding quality depends heavily on the original material.
