1. A method of video encoding, comprising:
performing an intra prediction for a plurality of sub-partitions of a coding block in a Intra Sub-Partition (ISP) mode in response to determining that the plurality of sub-partitions meet first conditions for the intra prediction, wherein the coding block has a square shape or a rectangular shape,
wherein performing the intra prediction for the plurality of sub-partitions of the coding block comprises:
merging at least two sub-partitions of the plurality of sub-partitions into one prediction region for the intra prediction, and
generating predicted samples for the one prediction region in the intra prediction based on a plurality of reference samples of the coding block adjacent to the one prediction region,
wherein the first conditions comprise that the plurality of sub-partitions are a plurality of vertical sub-partitions and each of the sub-partitions has a width less than or equal to 2.
