Selecting deinterlace filter
The best deinterlace filter depends on the nature of the video image and
should be chosen by experimentation. A brief description of the four
algorithms is given here. For more information, see the home page of the
developers, listed in the dialog box.
Weave
This method uses three fields in the calculation and works well on slow
moving material but tends to fail on fast moving material.
Bob
The basic bob algorithm uses the most recent field and fills in the lines
between by interpolation. This method detects weaving artifacts in the
current image it uses bob to get rid of them. This method has a tendency to
bob rather too much and gives poor results on fine static images.
2-frame
This method uses the current frame and the last two to determine whether
to bob or weave a given pixel. This gives better results on both stationary
and moving images than the above two methods but uses more CPU.
