Abstract
Video processing methods for coding a current block comprise receiving input data of a current block, checking whether a sub-block motion compensation coding tool is applied to the current block based on a size, width, or height of the current block, a size, area, shape, width, or height of sub-blocks partitioned from the current block, an inter prediction direction of a sub-block Motion Vector (MV), primary MV, or one of control point MVs of the current block, a primary MV, the control point MVs, affine parameters; encoding or decoding the current block using the sub-block motion compensation coding tool or another coding tool according to a result of the checking indicating whether application of the sub-block motion compensation coding tool is valid or invalid; and a MV clipping process is applied to each sub-block in the current block if the checking result is false, indicating the validity is invalid.
