According to the high-definition video encoding / decoding method and apparatus to do this, setting the size of the prediction unit to be coded according to at least one temporal frequency characteristic between a picture or the spatial frequency characteristics to be encoded by the extended macro Bullock size and set prediction unit size unit to perform motion estimation and motion compensation, and performs the conversion. Furthermore, after on the basis of a macro block having 32x32 pixels or 64x64 pixels in size in the edge divided into at least one partition it performs encoding for each partitioned. Therefore, the coding efficiency can be improved for high resolution video than HD (High Definition) grade.
