1. A method comprising:

  • assessing a spatial continuity relative to a first block of a video frame of video data;

    assessing a temporal continuity relative to the first block of the video frame of video data, wherein assessing the temporal continuity comprises determining to utilize an estimated motion vector based on motion vectors of neighboring blocks, and wherein assessing the temporal continuity further comprises;

    calculating a weighted difference between a processed motion vector of the first block of the video frame and a motion vector of a corresponding block of a previous frame of the video data,comparing the weighted difference to a threshold, andin response to the weighted difference exceeding the threshold, determining an estimated motion vector that is a median value of motion vectors of neighboring blocks in a three block by three block array that includes the first block corresponding to the processed motion vector; and

    assigning a motion vector to the first block based on the spatial continuity and the temporal continuity.
