Abstract
A method of decoding video data includes determining that a geometric partition mode is enabled for a current block of the video data and determining a split line dividing the current block into a first partition and a second partition, where determining the split line comprises selecting an angle for the split line from a plurality of angles, Each angle of the plurality of angles corresponding to an N:M ratio of samples of the current block, where N and M are integers. The split line is not at a corner of the current block. The method further includes determining geometric mode weights for the current block using the angle of the split line, generating a first prediction block using motion information for the first partition, and generating a second prediction block using motion information for the second partition.
