Embodiments include methods and apparatuses for decoding video data including receiving an encoded video bitstream that forms a representation of a coded picture of the video data and determining a partitioning of the coded picture of the video data into a plurality of coded unit. The partitioning may be according to a first tree structure and the plurality of coded units including a leaf node in the first tree structure. A method may further include determining that a residual block of the leaf node is recursively split into a plurality transform units according to a second tree structure.
