Claim 10:
11. A system, comprising:
an encoder configured to:
perform a first pass encoding of a two-pass encoding process on a first frame of a stream of frames using a first-pass reference frame; and
perform a second pass encoding of the two-pass encoding process on the first frame using a second-pass reference frame and according to an adjusted complexity, wherein the second-pass reference frame is different from the first-pass reference frame; and

a rate control unit configured to:
determine a complexity of the first frame from the first pass encoding of the first frame; and
modulate the complexity of the first frame based on a quality difference between the second-pass reference frame and the first-pass reference frame so as to produce the adjusted complexity.
