Just a little help about deintelace

[MoonWalker]

Well I need some help :p

So far I have enocded only DVD's that are progresive(99%) and purely interlaced(1%)..R-2 DVD's..Now I got Indipedence Day witch it's a llitle weird..Some frames are proggresive, some intelaced and some both(half frame proggresive and the ther half interlaced)..I used feildeinterlace but it generates ghosting..I also tried smartdeintelace with the same result..Is there anything I can do?.Should I use another filter(ie telecide or somethink like that)?

Thanks,
MoonWaker

P.S I encode with DivX 3.11

"Fieldeinterlace" is fine (decomb) also in vdub the "deinterlace area based" of Gunnar Thalin, but to avoid ghost :eek: always set or use interpolation beside blend(but some times spec. on Anime this produce weird artifacts :)) in "Fieldeinterlace(Blend=False)",
in "deinterlace area based" uncheck "blend instead of interpolate"

Some more explanations...In DVD2AVI when I select swap field order tha interlaced frames become progressive and the proggresive interlaced..Should I leave this on? At decomb should I use any pattern??

Maybe you should try using decomb settings for hybrid movies.

Telecide()
Decimate(mode=1,threshold=50)

@MoonWalker
With a Cowboy Bebop(DVD) i have the same behaviour but i let it "off"
and let decomb make the work, i will search mi HD and post late what param. i set for this clase of frames.

Good Luck.

I have tried Telecide()..It's better then feilddeinterlace but it has some ghosting...

Some more about the movie..I have count and I can't fin't any pattern that this happens..ie At the begining the movie has 500 intelaced frames the 1024 progresive then 1200 interlaced then 100 progressive etc..


@Kyo
Have you found your settings :) ?

Again, put the Blend=false into telecide() :)

I'm not sure but i found this for an cowboy ep!

Telecide(Reverse=True,Post=False,Blend=False,Guide=1,gthresh=25,dthreshold=30,threshold=20)

the reverse will/not improve the interlace detection so try first with Reverse=False.

Also i found that if i let Telecide make the postprocessing some frames go out jerky or bad when they are't interlaced ones.
so i put the Post=False BUT if you find that the interlaced ones pass FIRST try to reduce the gthresh or the threshold=20,( humm.. if I set Post=false the dthreshold=30 is ignored! :o )

But after reading your post seem that this source isn't a telecided one, so check again in TMPEG to see if really are this 1### interlaced and 1### progresives etc.. if they exist you must run only a deinterlace filter and pray ;)

Also more information about the source will be useful (Anime?)
Tests and Share!

The movie is Indipedence Day(Will Smith, Tomy Lee Jones :) )It's R2 PAL..It's the first movie I see like this.Not purely intelaced nor progressive..The weird is that it's not like interalce..It's like the feild order swaps from time to time..

Just a thought...Is there any filter that can detect the field order and if the field order changes it can swap it?? Bacause I see that the movie isn't exact interlace(as the term suggests) but is has parts with swapped field order..

EDIT

I have took a screen shot to see what I mean. Is't the original frame and the two fields..I used the separatefields command in avisynth..As you can see the original is like an "interlaced" one but in fact it isn't..

Try adding to decomb the parameter swap=true and test again!

[MoonWalker]

I used telecide(swap=true,blend=false)..And it's better...
But is there any filter that the only thing that does it if the field order swaps from a given order it will reverse it..
