Abstract: It provides a solution for video processing. A method for video processing is proposed. The method comprises: determining motion information for a video block of a video by conducting a refinement process on at least one of a first merge candidate or a second merge candidate for the video block, the second merge candidate being generated based on the first merge candidate; and performing a conversion between the video block and a bitstream of the video based on the motion information. Compared with the conventional solution, the proposed method can advantageously improve the coding performance.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: processing, during a conversion between a picture of a video and a bitstream of the video, a first video block in the picture based on a combination of decoder-side intra prediction mode derivation (DIMD) and multiple reference line (MRL), at least one intra prediction mode (IPM) being derived from the DIMD, and at least one non-adjacent reference line of reconstructed samples for the first video block being used in the combination of the DIMD and the MRL; and performing the conversion based on the first video block. Compared with the conventional solution, the proposed method can advantageously improve the coding effectiveness and coding efficiency.
