Claim 16:
17. A computer program product comprising a non-transitory storage medium including program code to be executed by at least one processor of an electronic device, whereby execution of the program code causes the electronic device to perform operations comprising:
obtaining a shifted pair of refinement parameters per a subblock of a bidirectional-predicted inter coding block, wherein the shifted pair of refinement parameters comprises a shifted first refinement parameter and a shifted second refinement parameter; and
determining a bi-directional optical flow, BDOF, offset without performing any right shifting using at least the shifted pair of refinement parameters by, for each sample in each subblock within each bidirectional-predicted inter coding block, determining the BDOF offset using the shifted first refinement parameter, the shifted second refinement parameter, a first horizontal gradient block and a first vertical gradient block for a first prediction block, and a second horizontal gradient block and a second vertical gradient block for a second prediction block.
