1. A method of coding video data, comprising:
determining, for a conversion between a picture of a video and a bitstream of the video, that a first block of a picture segment covers at least one region that is outside a border of the picture segment, wherein the picture segment represents one of a plurality of segments into which the picture is segmented, wherein a size of the first block is M×N pixels;
selecting a second block of size K×L pixels, wherein (K≤M and L<N) or (K<M and L≤N) and the second block falls entirely within the picture segment;
splitting, using a partition tree, the second block, wherein the second block is split into sub-blocks without an indication of the splitting, wherein a selection of a type of the partition tree used for splitting the second block is based on the size of the second block and further based on a size of a fourth block, wherein the fourth block falls entirely within the picture segment, wherein the size of the fourth block is smaller than the size of the second block, wherein the indication of the splitting is excluded from the bitstream, and wherein a size of at least one of the sub-blocks is identical to the size of the fourth block; and
performing the conversion based on the determining.
