1. An apparatus for encoding picture data of a video, comprising:
at least one processor configured to:
obtain the picture data;
determine that the encoding of the picture data should use independent coding trees for a plurality of luma and chroma blocks and determine the types of partitioning allowed for the chroma blocks;
insert a single flag and at least one parameter representative of types of partitioning allowed for the chroma blocks in a sequence parameter set of the encoded picture data, the single flag indicating that the encoding uses independent coding trees for the plurality of luma and chroma blocks; and
encode the picture data for at least one block in a picture and the sequence parameter set for a plurality of blocks to produce an encoded bitstream, wherein the encoding uses the determined types of partitioning allowed for the chroma blocks.
