1. A method of processing video data, comprising:
determining a dimension of a virtual pipeline data unit used for a conversion between a video and a bitstream of the video;
determining whether a first partitioning process that splits a current video block of the video into two sub-blocks or a second partitioning process that splits the current video block into three sub-blocks in a horizontal direction or a vertical direction is allowed or not at least based on the dimension of the virtual pipeline data unit; and
performing, based on the determining, the conversion,
wherein VSize=min(M, CtbSizeY), and wherein M is a positive integer equal to 64, CtbSizeY is a dimension of a coding tree block of the video and VSize is the dimension of the virtual pipeline data unit;
wherein the first partitioning process in the vertical direction is disabled in a case where (i) a sum of a width of the current video block in luma samples and a horizontal coordinate of a top-left luma sample of the current video block is greater than a width of a picture or a width of a sub picture comprising the current video block in luma samples and (ii) a height of the current video block in luma samples is greater than N, and wherein N is a positive integer equal to 64.
