A method for encoding a video picture into a bitstream of encoded video picture data, includes: obtaining a grid of coding-tree units to split at least one component of the video picture into coding-tree units, each coding-tree unit being a picture area subdivided according to a coding tree; determining at least one shifting offset by aligning at least one boundary of the grid of coding-tree units with at least one boundary separating picture areas with low spatial activity from picture areas with high spatial activity of the video picture; shifting the grid of coding-tree units according to the at least one shifting offset; obtaining encoded video picture data by encoding at least one coding unit (CU) of a coding tree associated with each coding-tree unit (CTU) of the shifted grid of coding-tree units; and writing the encoded video picture data into the bitstream.
