Abstract
A device for coding video data may determine whether a switchable interpolation filter (SIF) index value of a first motion vector (MV) component of a pairwise average motion vector predictor (MVP) is equal to a SIF index value of a second MV component of the pairwise average MVP. Based on the SIF index value of the first MV component being equal to the SIF index value of the second MV component, the device may set the SIF index of the pairwise average MVP to be equal to the SIF index of the first MV component. The device may code the video data based on the SIF index value of the pairwise average MVP.
