@ baker..
Yes, I was trying to say this earlier - couldn't get the words out right.
They interlace the frame, and in some cased, they will mix those frames
that are doubled, with the next frame.
So, to keep the frame rate smooth, they Telecining is not your tipicle one
that can be properly IVTC'ed.
I've noticed that they do this for non-animation sources as well. Like those
shows that would seem to be from Film, but are Telecined to 29.970 fps
with an unusual pattern, and not the 3,2 's that we are accustomed to.
A good example is 1960's Batman series. I'm not sure if they source had
originated as Film, and that they just did a very poor job of Telecining it,
OR, they "purposely" jimmy the Telecining process for obvious reasons,
but of which I don't beleieve in Batman's case, BUT that maybe they used
an unusual fps from a Telecining process that may have took placed back
in the 1960's for TV set back in those days, but that TODAY, they do not
choose to re-Telecine those good 'ol Batman series, cuase the source that
they DO have is more than adaquate enough for todays' TV set - an airing !!
I would theorize, that should they decide to release thoes 1960's Batman
series on DVD, that they would re-do the Telecining process, but only this
time, Correctly !! But, until they do this, it's only a theory and a dream

AND,
continue using .AVS script filtering, but rather perfect these types of
de-Telecining process using decomb.dll, if
Donald Graft can figure
out a cleaner method for these kinds of sources - I'm hoping and waiting

I like Donald's decomb.dll because it works in the majority of my projects
(give or take those interlace that slip by)
Well, this is about all I can muster up for now.
Have a good evening all.
