The subjects of prior threads are getting mixed in with this thread, "ffmepg architecture question".

The architecture question is about recursion/non-recursion of filter complexes.

The prior threads were about how to decomb a telecine in general and a 55-telecine in particular. 
Oh, well. It's my fault. I shouldn't have cranked one Jack-in-the-box before closing the previous 
Jack-in-the-box.

Regarding deinterlace, Carl Eugen, I'm not trying to deinterlace. The transcode source is 
progressive video (p24), not interlace video (i30-telecast or 125-telecast).

I'm performing p24-to-p60 transcode via 55 pull-down telecine. The result has 1 combed frame in 
every set of 5 frames (P P C P P). I'm trying to decomb those combed frames.

'pp' seems to do a better job of decombing because it has a procedure, 'pp=linblenddeint', that 
seems to do a better job of mixing the combed fields. 'yadif' seems to be optimized solely for 
deinterlacing.

To be clear: I will never be processing telecast sources and will never be deinterlacing.

Thank you all for being patient.

Regards,
Mark.
