UPDATE
Well, I guess the fieldmatch filter doesn't copy (cpnbu) fields. It instead makes tries at decombing
based on a cpnbu menu (passed as a parameter).
Does ffmpeg have a mechanism to *copy* fields based on the same cpnbu criteria
that fieldmatch employs?

I want to try the telecine filter to convert p24 by applying a pattern.

Apparently 'ffmpeg -i IN -f ? OUT' is not correct. Apparently '-f' is a switch for forcing
container formats (usually not needed as file extensions are normally used to set this).
Here's a filter description I found in '5.4 Main options' of the documentation:
Basically, I have successfully telecined 24 FPS video to a higher frame rate and totally banished
judder on a 60Hz TV (which should be true of 120Hz TV, too). WOO-HOO!
After searching the net all night, I found one sample of a telecine command that used the 'pattern'

relying on 'progressive' versus 'smpte170m'
I don’t think this distinction makes any sense.

Why do you say that, Carl Eugen?
If ffmpeg defines "progressive" as a video tha

I would guess that, for an undecoded video that's soft telecined (i.e.

I can't answer this for myself because I don't have the tools needed to probe into undecoded
macroblocks (at least, I don't think I have the tools).

Any idea where we can get builds for Windows after this date?
I plan to provide 64-bit static builds starting the 18th.

Admittedly, this is an anal-compulsive topic. But good documentation often requires anal compulsion.
Good documentation definitely requires thorough knowledge of language usage.
The topic is use of the various forms of the word "interlace". But I'm going to use the word "build"
