exist any filter specially done for (deinterlace) flicker

[Terka]

Some idea, maybee worth maybee not.
o=original lines
b=bobbed (computed) lines
t=original tempgaussed
T=bobbed tempgaussed
-=no lines

orig:
o-o
-o-

bobbed:
obo
bob

bobbed tempgaused:
tTt
TtT

to do (is easy):
oTo
ToT

n=new way of using TG
to do:
ono
non

Lets use the TempGausMC usual way for deinterlace:
Use the original lines & the deinterlaced-TempGaussed.
So because TGMC changes original lines too, after
joining o with bt will improve sharpness, but increase flicker.
So let the TG more change the b, not the o.
Ive seen somewhere that for mcdenoisig is used some duplication of frames,
to increase their weight.It was something like:
ooobOOO , o=(1.frame ),O=(2.frame)
so the b=bobbed one will be changed more than the o=O=original.
