    Abstract: Devices, systems and methods for digital video coding, which include sub-block based inter prediction methods, are described. An exemplary method for video processing includes determining, for a conversion between a current block of video and a bitstream representation of the video, a maximum number of candidates in a sub-block based merge candidate list and/or whether to add sub-block based temporal motion vector prediction (SbTMVP) candidates to the sub-block based merge candidate list based on whether temporal motion vector prediction (TMVP) is enabled for use during the conversion or whether a current picture referencing (CPR) coding mode is used for the conversion, and performing, based on the determining, the conversion.

    Abstract: Techniques for implementing video processing techniques are described. In one example implementation, a method of video processing includes determining, for a conversion between a current block of a video coded using a combined inter and intra prediction (CIIP) coding technique and a bitstream representation of the video, an intra-prediction mode of the current block independently from an intra-prediction mode of a neighboring block. The CIIP coding technique uses an intermedia inter prediction value and an intermedia intra prediction value to derive a final prediction value of the current block. The method also includes performing the conversion based on the determining.

    Abstract: Devices, systems and methods for digital video coding, which includes simplified cross-component prediction, are described. In a representative aspect, a method for video coding includes receiving a bitstream representation of a current block of video data comprising at least one luma component and at least one chroma component, predicting, using a linear model, a first set of samples of the at least one chroma component based on a second set of samples that is selected by sub-sampling samples of the at least one luma component, and processing, based on the first and second sets of samples, the bitstream representation to generate the current block. In another representative aspect, the second set of samples are neighboring samples of the current block and are used for an intra prediction mode of the at least one luma component.
