My experience is that regarding "decombing" frames 2 7 12 17 ...,
'pp=linblenddeint' (whatever it is) does a better job than 'yadif'.
(Funny that while I always strongly disagreed some people also
said this when yadif was new - this doesn't make it more "true"
in any useful sense though.)
I am splitting out solely frames (n+1)%5=3 and applying "deinterlace" solely to them as single
frames. For that application, 'pp=linblenddeint' appears to do a better job (visually) than does
'yadif'.
"lb/linblenddeint
"Linear blend deinterlacing filter that deinterlaces the given block by
filtering all lines with a (1 2 1) filter."
I don't know what a "(1 2 1) filter" is -- I don't know to what "1 2 1" refers.
To the fact that no other filter uses as little information to deinterlace.
To me, deinterlace just means weaving the odd & even lines. To me, a frame that is already woven
doesn't need deinterlacing. I know that the deinterlace filters do additional processing, but none
of them go into sufficient detail for me to know, in advance, what they do.
