But a filter could disable and enable its own effect on the fly.

How would that work?

And I don't know if filmdint is applicable for me anyway. I'm in the UK
(PAL) so I generally only encounter films that are at their original
24fps (imports etc) or that have been sped up slightly to 25fps (shown
on TV or region 2 DVDs). But a lot of TV programmes here are 25/50 fps
interlaced.
