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.

• Disabled
• Blind offset
• Smart analysis
