997	Calling of arguments in clause 8.5.2.14	chujoh		"There are two mistakes of calling for arguments in clause 8.5.2.14, which specifies the rounding process for motion vectors.


8.5.2.4	Derivation process for pairwise average merging candidate

–	The rounding process for motion vectors as specified in clause 8.5.2.14 is invoked with mvX[ 0 ] set equal to mvLXp0Cand[ 0 ] + mvLXp1Cand[ 0 ], mvX[ 1 ] set equal to mvLXp0Cand[ 1 ] + mvLXp1Cand[ 1 ], rightShift set equal to1, and leftShift set equal to 0 as inputs and the rounded '''mvLXavgCand[ 0 ]''' as output.

The above sentence should be improved by the following.

–	The rounding process for motion vectors as specified in clause 8.5.2.14 is invoked with mvX[ 0 ] set equal to mvLXp0Cand[ 0 ] + mvLXp1Cand[ 0 ], mvX[ 1 ] set equal to mvLXp0Cand[ 1 ] + mvLXp1Cand[ 1 ], rightShift set equal to1, and leftShift set equal to 0 as inputs and the rounded '''mvLXavgCand''' as output.

8.5.5.9	Derivation process for motion vector arrays from affine control point motion vectors
–	'''For i = 0..1, the following applies:'''
–	The rounding process for motion vectors as specified in clause 8.5.2.14 is invoked with mvX set equal to '''diffMvLX[ x ][ y ][ i ]''', rightShift set equal to 8, and leftShift set equal to 0 as inputs and the rounded '''diffMvLX[ x ][ y ][ i ]''' as output.
–	The value of diffMvLX[ x ][ y ][ i ] is clipped as follows:
diffMvLX[ x ][ y ][ i ] = Clip3( −dmvLimit + 1, dmvLimit − 1, diffMvLX[ x ][ y ][ i ]) 	(918)

The above paragraph should be improved by the following.

–	The rounding process for motion vectors as specified in clause 8.5.2.14 is invoked with mvX set equal to '''diffMvLX[ x ][ y ]''', rightShift set equal to 8, and leftShift set equal to 0 as inputs and the rounded '''diffMvLX[ x ][ y ]''' as output.
–	'''For i = 0..1, the following applies:'''
–	The value of diffMvLX[ x ][ y ][ i ] is clipped as follows:
diffMvLX[ x ][ y ][ i ] = Clip3( −dmvLimit + 1, dmvLimit − 1, diffMvLX[ x ][ y ][ i ]) 	(918)
