fov used seperate fields.select even or more
likely an equivalent deinterlacing method in
their source decoder. we reproduced the same
effect using directshowsource with the divx
h264 decoder and enabling deinterlacing in
the divx decoder config.
the use of this forbidden deinterlacing
method is most noticeable on the doctor's
shirt, for example from 28:29 to 28:34.
deinterlacing should be disabled in the
decoder that you use with directshowsource.
most sources are progressive and should not
be deinterlaced at all. and for sources that
should be deinterlaced use a deinterlacer
such as leakkerneldeint in your avisynth
script.
