11.2.4.9 Support of interlaced VOP
The Support of interlaced VOPs setting allows the Interlaced process.
This process, which is used to display a TV picture in PAL standard, displays two half frames
in succession. As the frame is generated, only the odd lines from the output device are
displayed for the first half frame and, one this is complete, the second half frame is
generated from the even lines. The two frames are coded separately. The relatively high
refresh frequency means that the eye picks this up as a single frame.
This function is not supported by all hardware.
11.2.4.10
Global Motion Compensation
The Global Motion Compensation setting is used to compensate for camera movement.
This is achieved by means of pre-set vector fields for motion vectors. The vector corrections
required if the vector fields are incorrect are less complex than the creation of a completely
new vector field..
This setting requires a lot of time with little increase in quality.
11.2.5 Keyframes
The Keyframes entry allows you to set the intervals between keyframes.
These setting options are only available if you have selected Nero Digital, Sony Memory
Stick-Video or Apple iPod in the Nero Digital category
11.2.5.1
Smallest/largest keyframe interval
The Keyframe Interval setting defines the maximum and minimum values for the GOP size.
Remember that the value for the largest interval may not be greater than 300, but should not
be set too low either because the coding efficiency at other locations can become poorer if
there are too many keyframes.
11.2.6 Matrices
The user can edit existing qualification matrices or upload their own matrices under
Matrices.
The matrices determine how the various frequencies in the macroblocks are displayed.
These setting options are only available if you have selected Nero Digital, Sony Memory
Stick-Video or Apple iPod in the Nero Digital category
11.2.6.1
Intra
The matrix in the Intra entry is responsible for the quantization of I macroblocks because this
is intracoded.
11.2.6.2
Inter
The matrix in the Inter entry is responsible for the quantization of P and B macroblocks
because these are intercoded.
