prediction check box is enabled.
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.
