In this paper we present an overview of the software tools currently available for the creation and display of MPEG-4 content. We first describe tools for encoding raw video into MPEG-4 compliant bitstreams. We then describe how this content may be used to create a complete MPEG-4 scene containing both graphical and interactive elements in addition to the more usual video and audio elements. Clearly, MPEG-4 content cannot be viewed without appropriate decoders and players and these are addressed in the third section of this paper. Finally, we demonstrate how these tools may be combined together to create MPEG-4 applications by presenting the details of two sample applications we have developed
