Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: determining, during a conversion between a target block of a video and a bitstream of the target block, an intra mode for the target block, the target blocking being coded with a geometric partition mode (GPM); storing the intra mode for the target block; and performing the conversion based on the stored intra mode.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: deriving, during a conversion between a target block of a video and a bitstream of the target block, a motion vector predictor for the target block from a parameter table that stores a set of affine parameters from at least one previously coded block, the target block being a non-affine coded block; and performing the conversion based on the motion vector predictor.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: applying, during a conversion between a target video block of a video and a bitstream of the video, a multi-hypothesis prediction process for the target video block based on a plurality of motion candidates from a non-regular merge list; and performing the conversion based on a result of the multi-hypothesis prediction process. Compared with the conventional solution, the proposed method can advantageously improve the coding efficiency and performance.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: determining, during a conversion between a target block of a video and a bitstream of the target block, a first prediction and a second prediction associated with the target block, the target block being applied with a multiple hypothesis prediction coding mode; applying a process associated with a template of the target block to the target block by blending the first and second predictions; and performing the conversion according to the process associated with the template.
