Abstract
Devices, systems and methods for digital video coding, which includes motion vector predictor derivation and signaling for affine mode with adaptive motion vector resolution (AMVR), are described. An exemplary method for video processing includes determining, for a conversion between current video block and a bitstream representation of the current video block using a coding tool that adaptively selects a resolution for each motion vector associated with the current video block, a final motion vector, wherein a precision of the final motion vector is identical to a precision of a stored motion vector of the current video block; and performing, based on the final motion vector, the conversion between the bitstream representation and the current video block.
