1. An apparatus for coding video data, comprising: a memory for storing the video data, the memory including a buffer; and a hardware processor operationally coupled to the memory and configured to: receive the video data to be coded; determine a quantization parameter (QP) of a current block of the video data without considering a type of content of the video data and a rate-distortion model associated with the type of content; and code the current block in a bitstream using the determined QP.
