Abstract: This disclosure relates to video coding and more particularly to techniques for intra prediction coding. In one example, a method of decoding video data, the method comprising: parsing a first syntax element having a value indicating an intra sub partitions (ISP) intra prediction is used for coding a current video block; parsing a second syntax element indicating whether a most probable mode (MPM) or a non-most probable mode (MPM) is an intra prediction mode used for generating a prediction for the current video block according to the ISP intra prediction; based on whether the second syntax element indicates the MPM or the non-MPM is an intra prediction mode used for generating a prediction, conditionally parsing one of: a third syntax element indicating the MPM, or a fourth syntax element indicating the non-MPM; and generating a prediction for the current video block based on the first syntax element.

Abstract: A method of performing motion vector prediction for coding video data is disclosed. A full precision motion vector mv is determined for generating a prediction for video block in a first picture. A rounded motion vector rmv having a less precision than the full precision motion vector mv is stored. A motion vector predictor candidate is generated for a video block in a second picture from the stored motion vector.

Abstract: A method of filtering reconstructed video data is disclosed. The method comprising: parsing a first syntax element used for setting cross-component filter coefficients; inputting a reconstructed luma picture sample array; deriving luma locations by using location corresponding to a current chroma sample; deriving a filter coefficient array by using the cross-component filter coefficients; deriving a variable by using the filter coefficient array and the reconstructed luma picture sample array defined by the luma locations; and deriving a scaled variable by using the variable, wherein the variable is modified by a sum of a sample of a current chroma block, which is defined by a predetermined location, and the scaled variable.

Abstract: A method of decoding video data by a device is provided. A merge subblock flag specifying whether subblock-based inter prediction parameters for a coding unit are inferred from neighbouring blocks is decoded. A motion vector difference merge flag is decoded if a value of the merge subblock flag is equal to zero and a value of a motion vector difference flag is equal to one. The motion vector difference merge flag specifies a prediction parameter with a motion vector difference is used, and the motion vector difference flag specifies whether a merge mode with motion vector difference is enabled.
