An example method includes deriving, responsive to determining to inherit affine motion information for a current block of video data located in a current virtual pipeline data unit (VPDU) from a neighboring block of video data located in a different VPDU, the affine motion information for the current block from two motion vectors of the neighboring block of video data regardless of whether the neighboring block of video data is coded with a 4-parameter affine model or a 6-parameter affine model. The example method further includes determining, based on the derived affine motion information for the current block of video data, a predictor block of video data; and reconstructing the current block of video data based on the predictor block of video data.
