Claim 18:
19. The non-transitory computer-readable storage medium of claim 18, wherein the plurality of programs further cause the computing device to perform:
obtaining control point motion vectors (MVs) of the first prediction sample I(i,j), wherein the control point MVs comprise the MVs of the top-left, top-right, and bottom-left corner blocks of one block that contains the video block;
obtaining affine model parameters derived based on the control point MVs;
obtaining a horizontal MV difference Δvx(i,j) and a vertical MV difference Δvy(i,j) for the first prediction sample I(i,j) based on the affine model parameters;
right shifting the horizontal MV difference Δvx(i,j) a second bit-shift value; and
right shifting the vertical MV difference Δvy(i,j) by the second bit-shift value.
