Setting Driver Properties

Adaptive Deinterlace window

Use the adjust dialog to adjust the parameters that control motion adaptive deinterlacing (Figure 32).

Note: When the driver is using the Inverse Telecine algorithm, either in Telecine mode or Auto mode, the Adjust settings have no effect at all, and Test Mode is inoperative.

Figure 32. Adaptive Deinterlace window

The Adaptive Deinterlace window has the following controls.

Motion Threshold

The Motion Threshold slider and edit box adjust the threshold of

 

difference from spatially and temporally related pixels that is judged to

 

be motion. If you enter Test Mode and move the slider to the right, the

 

number of pixels that are considered in motion is greatly reduced. As you

 

move the slider to the left, the number of motion pixels greatly increases

 

until nearly the entire screen is considered in motion. The recommended

 

default is 10.

 

 

Smooth Motion

The Smooth Motion option results in more loss of detail in motion areas,

 

but edges are smoother. Since the eye does not see detail clearly in

 

areas of motion anyway – whereas edge artifacts are always highly

 

intrusive – the Smooth algorithm should be preferred for most

 

applications. The Smooth algorithm uses a bit more CPU.

 

Note: Both algorithms treat still areas (areas that are not green

 

in Test Mode) the same way, and there should be no loss of

 

detail in still areas.
