We present a detailed blueprint of our stereoscopic free-viewpoint video system. Using unsynchronized footage as input, we can render virtual camera paths in the post-production stage. The movement of the virtual camera also extends to the temporal domain, so that slow-motion and freeze-and-rotate shots are possible. As a proof-of-concept, a full length stereoscopic HD music video has been produced using our approach.

We present an image-based rendering system to viewpoint-navigate through space and time of complex real-world, dynamic scenes. Our approach accepts unsynchronized, uncalibrated multi-video footage as input. Inexpensive, consumer-grade camcorders suffice to acquire arbitrary scenes, e.g., in the outdoors, without elaborate recording setup procedures, allowing also for hand-held recordings. Acquisition simplification, integration of moving cameras, generalization to difficult scenes, and space-time symmetric interpolation amount to a widely applicable Virtual Video Camera system.

Space-time visual effects play an increasingly prominent role in recent motion picture productions as well as TV commercials. Currently, these effects must be meticulously planned before extensive, specialized camera equipment can be precisely positioned and aligned at the set; once recorded, the effect cannot be altered or edited anymore. In this paper, we present an alternative approach to space-time visual effects creation that allows flexible generation and interactive editing of a multitude of different effects during the post-production stage. The approach requires neither expensive, special recording equipment nor elaborate on-set alignment or calibration procedures. Rather, a handful of off-the-shelf camcorders, positioned around a real-world scene, suffice to record the input data. We synthesize various space-time visual effects from unsynchronized, sparse multi-view video footage by making use of recent advances in image interpolation. Based on a representation in a distinct navigation space, our space-time visual effects (STF/X) editor allows us to interactively create and edit on-the-fly various effects such as slow motion, stop motion, freeze-rotate, motion blur, multi-exposure, flash trail, and motion distortion. As the input to our approach consists solely of video frames, various image-based artistic stylizations, such as speed lines and particle effects are also integrated into the editor. Finally, different effects can be combined, enabling the creation of new visual effects that are impossible to record with the conventional on-set approach.
