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.

Abstract: Embodiments of the present disclosure provide a solution for video processing is proposed. A method for video processing is proposed. The method comprises: determining, during a conversion between a video unit and a bitstream of the video unit, whether an optical flow based coding method is applied to the video unit based on illuminance information associated with at least one of: the video unit or a reference video unit of the video unit; and performing the conversion based on the determination. 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, for a conversion between a current block of a video and a bitstream of the video, that a first prediction mode is applied to the current block, deriving, in the first prediction mode, prediction samples of the current block based on reference values in a virtual buffer that are determined by a block vector for the current block; performing the conversion based on the prediction samples; determining a set of blocks from a plurality of blocks of the same video region based on coded information of the plurality of blocks, the plurality of blocks being coded before the current block; and updating the virtual buffer based on the set of blocks.
