A method of processing video data is described. The method includes performing a conversion between a current video block of a video and a bitstream of the video. A geometric partitioning mode index for the current video block is coded in the bitstream and a binarization of the geometric partitioning mode index is performed according to a rule. The geometric partitioning mode index specifies a geometric splitting shape of a geometric partitioning mode applied to the current video block. The rule specifies that the geometric partitioning mode index is coded with a fixed-length binarization.
