Abstract: An apparatus (e.g., a computer device) includes a video coding system. The video coding system includes an encoder. The encoder is configured to partition a block of video data into a first partition and a second partition, the first partition and the second partition being divided by a border that is at an angle to an orientation of a row or column of pixels, determine a first motion vector for the first partition and a second motion vector for the second partition, determine a first set of predictor values based on the first motion vector and a second set of predictor values based on the second motion vector, and combine the first set of predictor values and the second set of predictor values into an overall set of predictor values based on a weighting algorithm.

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.
