H.264 - Codec / Motion estimation

M.E. Range

The maximum range of the motion search in pixels.

Scene Change Sensitivity

The change required between frames for a scene change to be detected.

M.E. Algorithm

Set the motion estimation search algorithm.

  • Diamond  ( fastest )
  • Hexagon
  • Multi hex
  • Exhaustive ( slow )
  • SATD Exhaustive ( very slow )


Subpixel Refinement

Set the subpixel estimation complexity.

  • 0 - Fullpel only
  • 1 - QPel SAD
  • 2 - QPen SATD
  • 3 - HPel on MB then QPen
  • 4 - Always QPen
  • 5 - QPen & Bidir ME
  • 6 - RD on I/P frames
  • 7 - RD on all frames
  • 8 - RD refinement on I/P frames
  • 9 - RD refinement on all frames
  • 10 - QP-RD

Chroma M.E.

Searches both luma and chroma for motion information in the sub-pixel search.

Weighted pred. P-frames

Enables use of explicit weighted prediction to improve compression in P-frames.
