Deinterlace tab
Use the Deinterlace tab (Figure 25) to turn deinterlacing on or off, select a desired operating mode,
and instruct the card to detect telecined content, and apply appropriate compensation.

Advanced motion adaptive deinterlace
Motion adaptive deinterlace is an algorithm for deinterlacing pure video (non-telecine) content.
Motion adaptive deinterlace detects which portions of the image are still, and which portions are in
motion, and applies different processing to each. This can be somewhat CPU-intensive but is helpful
when the video consists of high-motion content. Simpler Bob and Weave algorithms can be
employed when video is relatively stationary, with a slight loss of sharpness. In some cases, such as
when the desired output frame vertical dimension is exactly half of the incoming dimensions, it may
be unnecessary to select deinterlacing
—
the scaling algorithm simply drops odd or even frames, that
is, drops the odd or even lines altogether to achieve the scaling.
Once you enable deinterlacing via the check box, you may select which algorithm to use:
•
Bob 0
•
Bob 1
•
Advanced
