      " This patch makes scene-cut detection based on the relative cost of I-frame
      vs P-frame, rather than just on the number of I-blocks used.
      It also makes the scene-cut threshold configurable.
      This doesn't have a very large effect: Most scene cuts are obvious to
      either algorithm. But I think this way is better in some less clear cut
      cases, and sometimes finds a better spot for an I-frame than just waiting
      for the max I-frame interval."

      "Improved patch. Now supports subpel ME on all candidate MB types,
      not just on the winner.
      subpel_refine: (completely different scale from before)
      0 => halfpel only
      1 => 1 iteration of qpel on the winner (same as x264 r46)
      2 => 2 iterations of qpel (about the same as my earlier patch, but faster
      3 => halfpel on all MB types, qpel on the winner
      4 => qpel on all
      5 => more iterations

      "The current code for calculating the cost of encoding which reference
      frame a MB is predicted from, introduces a bias towards ref0 and
      against P16x16.
      Removing this bias produces an improvement of .4% - 2% bitrate,
      depending on content and number of reference frames."
