Claim 0:
1. A method of video processing, comprising:
determining, for a conversion between a block of a video and a bitstream of the video, weights to use for a weighted average of prediction samples along an edge of two partitions of the block, wherein the two partitions are generated according to a geometry partition mode, wherein the weights are selected from a first weighting factor group of at least two weighting factor groups based on a first motion vector associated with a first partition and a second motion vector associated with a second partition; and
performing the conversion based on the determining,
wherein the first motion vector associated with the first partition is denoted as Mv0(x0, y0), the second motion vector associated with the second partition is denoted as Mv1(x1, y1), and wherein the second motion vector is scaled as Mv1′(x1′, y1′) according to a reference picture that the first motion vector points to, and
wherein the weights in the first weighting factor group are used in a case that a value of a function F with respect to (x1′, x0, y1′, y0) is larger than or equal to a threshold, and
wherein the threshold varies for different blocks having different characteristics.
