The purpose of this paper is to optimize the stereoscopic 3D experience when users watch those contents. We propose two factors in stereoscopic experience: visual fatigue and depth perception. In order to optimize stereoscopic experience, we propose five principles to reduce visual fatigue and enhance depth perception and implement them by cropping and warping. Using our methods, time-consuming problems of existing view interpolation methods such as camera calibration, accurate dense depth map, and inpainting are avoided. We also design a GUI that enables users to efficiently edit the stereoscopic video, optimize the stereoscopic experience, and preview the stereoscopic result. The user study shows that our method is successful in optimizing stereoscopic experience. One example is shown in Figure 1.
