Aspects of the disclosure provide a method and an apparatus for video coding. In some examples, an apparatus includes processing circuitry that obtains a plurality of control point motion vectors for a current block, determines first motion vectors and second motion vectors for a plurality of sub-blocks of the current block according to the plurality of control point motion vectors. The first motion vectors correspond to a first relative position in each sub-block. At least one first motion vector is different from a corresponding second motion vector. The processing circuitry obtains a first set of predicted samples according to the first motion vectors, obtains a second set of predicted samples according to the second motion vectors, and obtains a third set of predicted samples for the current block based on the first set of predicted samples and the second set of predicted samples.
