Claim 9:
10. The method of claim 6, wherein the prediction block is a first prediction block, the current block is a first current block, the horizontal displacement and the vertical displacement are a first horizontal displacement and a first vertical displacement, the one or more refinement offsets are first one or more refinement offsets, the rounded horizontal displacement and the rounded vertical displacement are a first rounded horizontal displacement and a first rounded vertical displacement, the modified prediction block is a first modified prediction block, and the residual values comprise first residual values, the method further comprising:
determining a second prediction block for inter-predicting a second current block;
determining second horizontal and vertical displacements for gradient-based prediction refinement of one or more samples of the second prediction block;
rounding the second horizontal and vertical displacements to the same precision level to which the first horizontal displacement and the first vertical displacement were rounded to generate second rounded horizontal and vertical displacements;
determining second one or more refinement offsets based on the second rounded horizontal and vertical displacements;
modifying the one or more samples of the second prediction block based on the determined second one or more refinement offsets to generate a second modified prediction block;
determining second residual values indicative of a difference between the second current block and the second modified prediction block; and
signaling information indicative of the second residual values.
