Thanks Marco. In all of this there is a significant point that (I believe)
has not occurred to people. All interlaced displays have motion artifacts.
To see this consider a single contrasting pixel moving vertically at exactly
60 lines per second; depending on its odd-even field phasing, the pixel
will either be visible or totally invisible. At rates close to 60 lines per
second (and its harmonics) the pixel will flicker at a difference frequency.
This "second-order flicker" has nothing to do with the normal flicker of
static interlaced Amiga displays. Flicker fixer changes the appearence of
motion artifacts and users who are concerned with the de-interlaced appearence
of animated displays should look at the display to determine if it is
suitable for their application.  I think it is fair to say that the majority
of users have found this to be a non-issue.  Regards,

--------
Enjoy.
