1. A method of processing video data, comprising:
determining, for a conversion between a current video block of a video and a bitstream of the video, whether to enable a geometric partitioning mode coding tool based on a first syntax element indicative of application of a combined inter-picture merge and intra-picture prediction mode and a second syntax element indicative of application of a regular merge mode; and
performing the conversion based on the determining,
wherein in the geometric partitioning mode coding tool, a first motion information for a first geometric partition of the current video block and a second motion information for a second geometric partition of the current video block is determined and a weighting process for generating a final prediction for samples within a weighted area of the current video block is applied based on a weighted sum of prediction samples derived based on the first motion information and the second motion information, and
wherein the first syntax element is not present in the bitstream in case the current video block has a block width greater than or equal to a first threshold KO or a block height greater than or equal to a second threshold K1, where K0 and K1 are integers.
