Carl,

I understand that mencoder doesn't do it. This was the answer to the 
very first email I had sent. However, you mentioned that ffmpeg might be 
able to do it?

My last email also stated that my source material is >>>not<<< 
interlaced but I am temporarily interlacing it via tinterlace=4 to be 
able to perform a filmdint. (A similar method is described here for 
something entirely different) -. http://mdsh.com/wiki/jsp/Wiki?Mencoder.

I do *not* want to deinterlace my *progressive* source. I found a way 
back from the captured 60 fps to 24 fps. This does not work or at least 
not reliably work with the simple filmdint filter. However, it does work 
if you apply the interlace filter first. Please wait for the sample (I 
am trying to cut somethng short together as I type this) and then see. 
Again: Input is fps 60 from broadcast analog captured. What was 
broadcast was a movie. Output after my trickery is 24fps - the original 
movie frame rate. I have not seen any commercial tool anywhere that can 
do this but mencoder can given the right parameters.
