Method, apparatus, and medium for video processing

An apparatus for video processing comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to perform acts comprising:

• determining, for a conversion between a current video block of a video and a bitstream of the video, a prediction for the current video block based on a plurality of sub-partitions of the current video block and at least one intra prediction mode, wherein the current video block is a chroma block, the plurality of sub-partitions are obtained by partitioning the current video block based on at least one partitioning mode, and the at least one partitioning mode is dependent on information associated with the current video block;
• and
• performing the conversion based on the prediction for the current video block.

A non-transitory computer-readable storage medium storing instructions that cause a processor to perform acts comprising:

• determining, for a conversion between a current video block of a video and a bitstream of the video, a prediction for the current video block based on a plurality of sub-partitions of the current video block and at least one intra prediction mode, wherein the current video block is a chroma block, the plurality of sub-partitions are obtained by partitioning the current video block based on at least one partitioning mode, and the at least one partitioning mode is dependent on information associated with the current video block;
• and
• performing the conversion based on the prediction for the current video block.

A non-transitory computer-readable recording medium storing a bitstream of a video which is generated by a method performed by an apparatus for video processing, wherein the method comprises:

• determining a prediction for a current video block of the video based on a plurality of sub-partitions of the current video block and at least one intra prediction mode, wherein the current video block is a chroma block, the plurality of sub-partitions are obtained by partitioning the current video block based on at least one partitioning mode, and the at least one partitioning mode is dependent on information associated with the current video block;
• and
• generating the bitstream based on the prediction for the current video block.
