The general aspects extend motion modes, such as merge with motion vector difference, and symmetrical motion vector difference, to motion models beyond a simple translational model, for example in combination with merge and alternative temporal motion vector prediction modes. Embodiments extend the use of MMVD and SMVD motion vector coding tools to all the motion model derivation methods and temporal prediction methods that are supported in proposed video standards, so as to increase the overall compression performance. Particular embodiments describe combining MMVD or SMVD with the affine motion model, the ATMVP motion model, the planar motion model, the regressive motion field, the triangle-partition-based motion model, the GBI temporal prediction method, the LIC temporal prediction method and the Multi-hypothesis prediction method.
