How well would smartdecimate work on Evangelion?

[Chainmax]

A friend of mine is about to get a hold of the DVDs and try to rip them. I'm pretty sure the discs he'll get aren't the Revival ones, so I wanted to suggest him an easy way to IVTC them with at least average results. I though of suggesting him SmartDecimate(24,60,bob=DGBob(mode=0)). Is that a good idea?

[scharfis_brain]

this is a very good idea.

I really like smartdecimate's bob-feature.

I usually use

x=fastbobmatcher #(or my non-publicated intellibob)
smartdecimate(24,60,bob=x,tel=?)

for tel place a value between 0 to 1 that specifies the amount of bobbing on unsure scenes (is it interlaced or telecine ?!?)
0.0 returns the bobbed only
1.0 returns weaved only

I was thinking about suggesting him to use bobmatcher as you recommended me for GotF, but the idea of not being able to autoload filters kinda defeats the whole "simple and fast" idea.

I have a question: what would be the advantage of using bobbing instead of weaving on unsure scenes? Wouldn't that create short spikes of VFR on the video?

[scharfis_brain]

unsure scenes are those ones not dectected either as video neither as film, thus smartdecimate isn't able to create a possible correct match of the fields.

this means the weaved (tel=1.0) output may contain interlacing due to false matching

this is avoided when outputting a (smart)bobbed clip interpolated basing on the current field. this avoids remaining interlacing.
and if smartbobbed with bobmatcher you'll be able to retain most of detail.

intellibob? sounds... intelligent.

any infos, or is it not worked out yet?

[scharfis_brain]

intellibob only deinterlaces those areas really filled with motion.
this means:
- progressive (telecined) video will become full 50 or 60 fps without getting touched

- hybrids (even frame hybrids) aren't touched by any kind of interpolation.
frame-hybrids are two progressive streams that are mixed together, but one of both streams is phase-shifted.

- true interlaced video gets lesser deinterlacing without raising remaing combing.

- scenechanges are never getting deinterlaced

this is achieved with forward/backward deinterlacing.
even the interpolation kernel (kerneldeint) is switched for forward and backward interpolation.
this means interpolated areas are getting the best possible resoltion, because the best fitting field (ext or prev.) ist choosen for interpolation.

my scripüt is too much crappy for now to publicate it.
I have to restructurize it and cut out some debugging etc.

It is not really usable for now, because I HAVE NO GOOD COMB-MASK!!!! :(
and my self-build helper-mask is *very* slow.

long story short: all in all intellibob is a per-pixel bobmatcher.

[Mug Funky]

aaaaahhhh. fair enough.

hmm. let's open a thread for the "comb mask challenge". maybe somebody will find a novel way of detecting combs and only combs, no matter how slow.

if it bleeds, we can kill it.
