A video stream for a scene for a virtual reality or augmented reality experience may be stored and delivered to a viewer. The video stream may be divided into a plurality of units based on time segmentation, viewpoint segmentation, and/or view orientation segmentation. Each of the units may be divided into a plurality of sub-units based on a different segmentation from the units, via time segmentation, viewpoint segmentation, and/or view orientation segmentation. At least a portion of the video stream may be stored in a file that includes a plurality of the units. Each unit may be a group of pictures that is a sequence of successive frames in time. Each sub-unit may be a vantage defining a viewpoint from which the scene is viewable. Each vantage may be further divided into tiles, each of which is part of the vantage, limited to one or more particular view orientations.
