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
2-Frame Algorithm
The 3-frame algorithm detects areas of motion and synthesized adaptive
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
