Abstract: At least a method and an apparatus are presented for efficiently encoding or decoding video. For example, for a block being encoded, a set of predictor candidates is determined. For a current potential predictor candidate in a set of potential predictor candidates, it is determined that the current potential predictor candidate is different from any predictor candidate in a subset of predictor candidates from the set of predictor candidates and in response the current potential predictor candidate is added to the set of predictor candidates. Thus, the set of predictor candidates is pruned with partial comparison in the set. The block is encoded or decoded based on a predictor candidate from pruned set of predictor candidates.
