A method of individually setting the quantization parameter for each coding unit of a frame in high efficiency video coding (HEVC) is disclosed. The method for setting a quantization parameter for each coding unit in a frame for HEVC encoding includes receiving at least one of partition size information of the coding unit and prediction mode information of the coding unit, performing an adaptive bit allocation operation per each coding unit based on at least one of the unit partition size information of the coding unit and the prediction mode information of the coding unit, and setting a quantization parameter per each coding unit according to the performed adaptive bit allocation operation.
