1. A method for processing video content, comprising:
partitioning, along a partitioning edge, a first block associated with a picture into a first partition and a second partition, the partitioning comprising:
determining a target partitioning manner according to a partition mode index, an angle index, or a distance index; and
determining the partitioning edge corresponding to the target partitioning manner;
performing inter prediction on the first block, to generate a first prediction signal for the first partition and a second prediction signal for the second partition;
determining a first offset and a second offset based on a size of the first block, an angle value of the target partitioning manner, and a distance value of the target partitioning manner, wherein the first offset and the second offset are determined based on the below equations:

, wherein “W” represents a width of the first block, “H” represents a height of the first block, “A” represents the angle value of the targeting partitioning manner, and “D” represents the distance value of the targeting partitioning manner;
generating, using the first and second offsets, a plurality of blending weights for luma samples in the first block; and
blending the first and second prediction signals for luma samples surrounding the partitioning edge of the first block.
