Claim 20:
21. The computer program product of claim 17, wherein the determining the BDOF offset without performing any right shifting using the shifted pair of refinement parameters is determined in accordance with:

bdofOffset=(vx*(gradientHL0[x+1][y+1]−gradientHL1[x+1][y+1]))+(vy*(gradientVL0[x+1][y+1]−gradientVL1[x+1][y+1]))

where bdofOffset is the bidirectional optical flow offset BDOF offset, vx is the first refinement parameter, vy is the second refinement parameter, gradietHL0[x+1][y+1] is the first horizontal gradient block, gradientHL1[x+1][y+1] is the second horizontal gradient block, gradientVL0[x+1][y+1] is the first vertical gradient block, and gradientVL1[x+1][y+1] is the second vertical gradient block.
