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 current video part of a video and a bitstream of the video, a process applied to the current video part at least based on coding information of the current video part, the determined process comprises at least one of an upsampling process or an enhancement process; and performing the conversion based on the determined process. The method in accordance with the present disclosure improves the coding process of the current video unit. Compared with the conventional solution, the proposed method can advantageously improve the coding efficiency and an image/video of larger size with more pixels and better visual quality is achieved.

Abstract: Embodiments of the disclosure provide a solution for video processing. A method for video processing is proposed. The method includes: determining, during a conversion between a video unit of a video and a bitstream of the video unit, information of a previously coded picture associated with the video unit; during a filtering process, filtering at least one sample in a current picture associated with the video unit based on the information; and performing the conversion based on the filtered at least one sample.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing comprises: determining, during a conversion between a current video block of a video and a bitstream of the video, a first filter shape from a plurality of filter shapes; determining, based on the first filter shape, a first filter for coding a first sample of the current video block, a value of a clip parameter of the first filter being dependent on the first filter shape; and performing the conversion based on the first filter. Compared with the conventional solution, the proposed method can advantageously improve the performance of the filtering tool.

Abstract: Embodiments of the present disclosure provide a solution for processing video data. A method for processing video data is proposed. The method comprises: constructing, based on a plurality of intra prediction modes, a candidate list for a current block of a video, the number of the plurality of intra prediction modes being smaller than a preset value; and performing a conversion between the current block and a bitstream of the video based on the candidate list, an intra prediction mode of the current block being derived based on neighbouring samples of the current block. Compared with the conventional solution, the proposed method can advantageously improve the coding efficiency.
