1. A method, comprising:
obtaining unidirectional triangle candidates from a merge list for encoding a video block;
extracting portions of said unidirectional triangle candidates;
obtaining triangle merge candidates from a sub-block merge list of candidates, wherein the sub-block merge list in triangle partition mode is restricted based on dimensions of the video block;
extracting unidirectional seeds portion of said triangle merge candidates;
performing motion compensation on said video block using said portions of the unidirectional triangle candidates and said triangle merge candidates;
weighting the motion compensated video block;
signaling whether a sub-block or regular list of candidates was used for said motion compensated results; and
encoding the weighted motion compensated video block.
