Claim 8:
9. A method, comprising:
determining a motion vector for predicting motion of a current block of a 360 degree video based on a location of a pixel of the current block within a video frame including the current block and based on a motion prediction of the pixel determined on a sphere representative of the 360 degree video from the location of the pixel to a predicted location of the pixel according to rotation parameters associated with the current block; and
encoding the current block based on the motion vector,
wherein a block partition size for the current block is determined based on a density distortion according to a location of the current block on the sphere and is between a minimum block partition size and a maximum block partition size defined for a latitude range of the sphere which includes the location of the current block on the sphere.
