Method and apparatus for video coding

An apparatus, comprising processing circuitry configured to:

• decode prediction information of a current block in a current picture from a coded video bitstream, the prediction information being indicative of inter prediction;
• determine, for the current block, motion information including a first motion vector (MV) that has a x component and a y component wherein each of the x and y components has a fractional MV precision that is 2−N of a sample size in the current block and has one of 2L+1 MV values with the fractional MV precision, N being 4 and indicating the fractional MV precision, L being a positive integer and indicating a fractional MV range, and each of the x and y components being within the fractional MV range with the fractional MV precision;
• and
• reconstruct at least one sample of the current block based on the motion information.

A non-transitory computer-readable storage medium storing a program executable by at least one processor to perform:

• decoding prediction information of a current block in a current picture from a coded video bitstream, the prediction information being indicative of inter prediction;
• determining, for the current block, motion information including a first motion vector (MV) that has a x component and a y component wherein each of the x and y components has a fractional MV precision that is 2−N of a sample size in the current block and has one of 2L+1 MV values with the fractional MV precision, N being 4 and indicating the fractional MV precision, L being a positive integer and indicating a fractional MV range, and each of the x and y components being within the fractional MV range with the fractional MV precision;
• and
• reconstructing at least one sample of the current block based on the motion information.
