Check box

Quarter pixel

precision

If this check box is selected, a quarter of a pixel instead of a pixel is

used for motion estimation and compensation. The movement

across the frame will be more accurate.

This option often improves the quality. However, older standalone

DVD players may not be able to playback files encoded with this

option.

Check box

Global motion

compensation

If this check box is selected, the encoder tries to compensate for

camera movement. This is achieved by means of previously

generated vector fields for the motion vectors. The vector corrections

required when the vector fields do not match are less complex than

the complete generation of a new vector field.

This setting requires a lot of time for relatively little increase in

quality.
