Motion vectors used for bi-prediction of a block of a current picture are predicted and reconstructed by determining candidate motion vector predictors for each of two motion vector predictor lists. A reconstruction order for the motion vector predictor lists is selected based on the candidate motion vector predictors. In video coding, motion vector deltas are generated for the motion vector predictor lists according to the selected reconstruction order and in video decoding, reconstructed motion vectors are generated for the motion vector predictor lists according to the selected reconstruction order. A candidate motion vector predictor of the second motion vector predictor list is replaced by the actual or reconstructed motion vector for the first motion vector predictor list or a scaled version thereof. This selection of reconstruction order enables determining better candidate motion vector predictors and thereby resulting in smaller motion vector deltas.
