Factors in Preserving Video Quality in Postproduction When Cascading Compressed Video Systems

Postproduction equipment increasingly uses video compression to achieve economies of storage and bandwidth. Users of compressed video systems need to be aware of the factors that determine video quality. As compression technology becomes more widespread, the cascading of multiple compression systems increases. The compression techniques which are optimal for transmission and distribution of video are not the same as those which are optimal for postproduction. This paper defines the important factors that determine video quality in compression systems. It describes the differing requirements placed on compression by postproduction and distribution. It concludes by examining results from three cascaded compression experiments using JPEG and MPEG-2.
