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 present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: obtaining a reference picture for a target picture of a video; determining whether the reference picture is to be used for filtering the target picture based at least in part on a difference between the reference picture and the target picture; and in accordance with a determination that the reference picture is to be used for filtering the target picture, performing temporal filtering on the target picture based on the reference picture. Compared with the conventional solution, the proposed method can advantageously improve the coding speed and efficiency.
