8 Claims

1. A method for video encoding, comprising:

accessing a block of a picture in a video sequence;

generating a list of motion vector predictors for said block,

wherein said block is to be encoded by using one of a plurality of coding modes,

wherein said plurality of coding modes correspond to all available non-sub-block coding modes that use a motion vector predictor list or all available sub-block coding modes that use a motion vector predictor list;

wherein said list of motion vector predictors includes a plurality of spatial predictors,

wherein, for each of said plurality of coding modes, the first spatial predictor in said list is from a top neighboring block, and the second spatial predictor following the first spatial predictor is from a left neighboring block; and

encoding a motion vector associated with said block based on said list of motion vector predictors.
