Adaptive Deinterlace window

Use the adjust dialog to adjust the parameters that control motion adaptive deinterlacing (Figure 37).

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 37. Adaptive Deinterlace window

The Adaptive Deinterlace window has the following controls.

Motion Threshold	The Motion Threshold slider and edit box adjust the threshold of change
	of 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 12.
3-Frame Algorithm and The 3-frame algorithm detects areas of motion and synthesized adaptive
2-Frame Algorithm	pixels for those areas by looking at three frames of video – the current
	frame, the frame before it, and the frame after it. The 2-frame algorithm
	refers to just two frames. 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.

The tradeoffs are:

∙The 30frame algorithm results in slightly more accurate
