Claim:
1. A computer-implemented method for video coding comprising: determining, for a first frame of a video sequence, whether the first frame is a scene change frame, a first golden frame distance to a previous golden frame, and a first average temporal distortion and determining, for a second frame of the video sequence, a second golden frame distance to the previous golden frame and a second average temporal distortion; designating the first frame as a golden frame or as a non-golden frame based on whether the first frame is a scene change frame, the first golden frame distance, and the first average temporal distortion and designating the second frame as a golden frame or as a non-golden frame based on the second golden frame distance and the second average temporal distortion, wherein the first golden frame distance is between a minimum golden frame interval and a default golden frame interval, the second golden frame distance is between the default golden frame interval and a maximum golden frame interval, designating the first frame as a golden frame or as a non-golden frame is based on a comparison of the first average temporal distortion to a first threshold, and designating the second frame as a golden frame or as a non-golden frame is based on a comparison of the second average temporal distortion to a second threshold less than the first threshold; and determining a quantization parameter for at least a portion of the first frame based on the designation of the first frame as a golden frame or as a non-golden frame and a temporal distortion of the first frame.
