Did a quick comparison of some methods. I post the script as well, in case I've made an error in the hurry ...



script:

mpeg2source()
crop(much)
orig=last
ox=last.width
oy=last.height
jaggy=orig.separatefields().selecteven()
SangN=jaggy.antialiasing().lanczosresize(ox,oy)
SangNSS=jaggy.lanczosresize(ox,oy).antialiasing()
tom=jaggy.tomsmocomp(1,-1,0)
tomSS=jaggy.lanczosresize(ox,oy).tomsmocomp(1,-1,1).lanczosresize(ox,oy)
trit=orig.tdeint(mode=0,order=1,field=1,mthreshL=-1,mthreshC=-1,type=1)
tritSS=jaggy.pointresize(ox,oy).tdeint(mode=0,order=1,field=1,mthreshL=-1,mthreshC=-1,type=1)
dble=jaggy.pointresize(ox,oy).tdeint(mode=0,order=1,field=1,mthreshL=-1,mthreshC=-1,type=1)
 \                           .tomsmocomp(1,-1,1).lanczosresize(ox,oy)
dbleS=dble.LimitedSharpen(ss_x=2.0,ss_y=1.0,Smode=3,strength=200,Lmode=2,overshoot=1)

# without the dreadful subtitle commands:
stackvertical(
 \ stackhorizontal(jaggy.lanczosresize(ox,oy).subtitle(jaggystr,size=12),orig),
 \ stackhorizontal(SangN,SangNSS),
 \ stackhorizontal(tom,tomSS),
 \ stackhorizontal(trit,tritSS),
 \ stackhorizontal(dble,dbleS) )

return last

edit: better placing of cropped area.
