Embodiments include systems and methods of performing intra-prediction using enhanced interpolation filters, including applying variable types and degrees of smoothing based on information such as block size, intra-prediction mode. An encoder or decoder may determine an intra-prediction mode for predicting a block of video data and determine a type of smoothing filter to use for the block of video data. The type of the smoothing filter to be used for performing intra-prediction for the block may be determined based on comparing at least one of a width of the block of video data and a height of the block of video data to a threshold.
