Abstract
An exemplary video encoding system accesses an image set that includes first and second consecutive color data images depicting a virtual reality scene from a particular vantage point, and first and second consecutive depth data images corresponding to the color data images. The system performs a first-pass video encoding of the image set by identifying motion vector data associated with a transformation from the first to the second color data image, and abstaining from analyzing a transformation from the first to the second depth data image. The system then performs a second-pass video encoding of the image set based on the identified motion vector data by encoding the first and second color data images into a color video stream to be rendered by a media player device, and the first and second depth data images into a depth video stream to be rendered by the media player device.
