1. A method, comprising:
obtaining, at a data reduction module, metrics of a first block of an input video frame to be an input to an encoder and a second block of an encoding reference frame, the encoding reference frame being fed back to the data reduction module from a quantization module of the encoder;
determining, at the data reduction module, a perceptual importance of the first block of the input video frame to be an input to the encoder using the metrics; and
adjusting, at the data reduction module, an entropy of the input video frame to be an input to the encoder based on the perceptual importance of the first block of the input video frame to be an input to the encoder.
