full rate telecide... is this a waste of time?

[Mug Funky]

hi all :)

i'm trying to decide whether IVTC'ing to 59.94fps is worth my while.

i can see it as useful for things like decimating for VFR purposes without busting your brain (there's tools that don't need this, but i don't read japanese), and also as useful for NTSC->PAL conversions, as a substitute for smart bobbing.

disadvantages i've seen so far:

- slow (by quite a bit)
- it's twice as important to have your settings perfect, because if a field isn't matched, the sequence is thrown off twice as long.

i've cobbled a script together for it, based on telecide (i haven't played with smartdecimate, as i don't have much NTSC stuff and rarely play with it)

assuming TFF:

odd = last.doubleweave().selectodd().telecide(order=0,guide=1,hints=true)
\.kerneldeint(order=0,threshold=3)
even = last.doubleweave().selecteven().telecide(order=1,guide=1,hints=true)
\.kerneldeint(order=1,threshold=3)
interleave(even,odd)


that's pretty damn simple compared to some scripts around here...
in addition, to field-blend, and then unblend the crisp parts (so effectively i get blend on pans and none on animation... i've posted this in other threads)


converttoyuy2().convertfps(50).converttoyv12()
unblend()
changefps(25)


this is a slow and inelegant way of performing a conversion, but it beats interlacing for compressibility, and doesn't look bad on the TV, at least with the stuff i've tried it on.

well, maybe this will be seen as useful :)

every read the smartdecimate doc?

smartdecimate(60,60)

will do fullframerate fieldmatching / teleciding

this mean your script may look like this:

smartdecimate(60,60)
converttoyuy2().convertfps(50).converttoyv12()
unblend()
changefps(25)

haha! i never actually downloaded smartdecimate...

i'll have to do this now, but it's a moot point - i finished the encode, with acceptable results. i don't care too much about it now because my friend just bought me the box set for this series in PAL (field blended, but hey i don't see that on the TV except on 30i pans)
