Utilization of motion information in affine mode

An apparatus for processing video data comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:

• acquire, during a conversion between a current block and a bitstream of the current block, motion information of the current block, wherein the motion information of the current block is based on at least one affine model parameter of a neighboring block of the current block;
• and
• perform, based on the motion information, the conversion between the current block and the bitstream of the current block.

A non-transitory computer-readable recording medium storing a bitstream of a video which is generated by a method performed by a video processing apparatus, wherein the method comprises:

• acquiring, during a conversion between a current block and a bitstream of the current block, motion information of the current block, wherein the motion information of the current block is based on at least one affine model parameter of a neighboring block of the current block;
• and
• generating the bitstream based on the motion information.
