Abstract PreViz is a computer graphics movie that represents desired scenes in preproduction and is useful for sharing the director’s imagination among crews. Therefore, film industry looks upon PreViz as one of the most important processes in filmmaking as the processes become complicated. Stereoscopic 3D (S3D) movie production not only changed ways of expressiveness but also changed ways of production and tools. Consequently, it requires more careful planning and PreViz is still important. This paper describes a prototype of S3D MR-PreViz system for HD S3D PreViz shooting using mixed reality (MR) technologies in order to facilitate PreViz making in S3D. This system is designed as an extension of MR-PreViz for classic filmmaking.

Live-action shooting in S3D is still challenging in spite of know how development. Developing intuitive interfaces, a motorized stereo rig and easy to use editing tools for disparity adjustments are proposed. Our motivation is, however, to offer stereographers the chance to examine properties of a stereo rig and camerawork before production. In this system, stereographers can shoot CGI characters acting on the indoor and outdoor set and on a miniature by themselves. Creating PreViz on their own, and not by animators, must be the most intuitive way. In addition, using actual images embodies depth rather concretely than usual PreViz in S3D.
