  • Publication number: 20240056599
    Abstract: The present disclosure relates to interaction between intra block copy mode and inter prediction tools. A method for video processing includes determining that an intra block copy (IBC) mode is applied to a current video block of a video. In the IBC mode, at least one reference picture used by the current video block is a current picture where the current video block is located. The method also includes making a decision regarding a disabling of a specific coding mode for the current block. The specific coding mode uses a motion vector and a non-current picture to derive a prediction of a video block. The method further includes performing, based on the decision, a conversion between the current video block and the bitstream representation.

    Abstract: Symmetric motion vector difference coding is described. One example video processing method includes determining, for a conversion between a block of a current picture of video and a bitstream representation of the block, whether a symmetric motion vector difference (SMVD) mode is allowable for the block. Whether the SMVD mode is allowable depends on a derivation process of two target reference pictures of the current picture, which includes a first step for searching a forward target reference picture in the reference picture list 0 and searching a backward target reference picture in the reference picture list 1, and a second step for searching a backward target reference picture in the reference picture list 0 and searching a forward target reference picture in the reference picture list 1. Outputs of the first and second steps are independent of each other. The method further includes performing the conversion based on the determination.
