Abstract: A method includes determining a tile position in a frame of a spherical video based on a view perspective, selecting a portion of the frame of the spherical video as a two dimensional tile based on the tile position, encoding the two dimensional tile at a first quality, mapping the frame of the spherical video to a two dimensional representation of the spherical video based on a two dimensional projection algorithm, and encoding the two dimensional representation of the spherical video at a second quality.
