Abstract: In one example, a method of encoding video data includes allocating, based on a complexity of a reference frame and a quantity of bits allocated to a current frame, a quantity of bits to a current largest coding unit (LCU) included in the current frame. In this example, the method also includes determining, based on the quantity of bits allocated to the current LCU, a quantization parameter (QP) for the current LCU, and encoding the current LCU with the determined QP.
