Hello,

I am trying to rip a dvd, but am having some trouble with it. I think I have it correctly IVTCed, but I am still having some trouble with "stair-stepping" on some areas, especially on areas that are red. Here is an example (capture from dgindex):

It is very clear around her red hair, as well as around her pink scarf. Are there any avisynth scripts that I could use to reduce this?

Also if anyone could check if I am IVTCing it correctly (some scenes where it pans across the screen are not smooth)? Here is my Avisynth script:

DGDecode_mpeg2source("episode.d2v",cpu=4,info=3)
ColorMatrix(hints=true,interlaced=true)
edeintted = AssumeTFF().SeparateFields().SelectEven().EEDI2(field=-1)
tdeintted = TDeint(edeint=edeintted,order=1)
tfm(order=1,clip2=tdeintted).tdecimate(hybrid=1)


Here is a small clip if anyone wants to take a look at it:

Sorry for all the newbie questions, its just that this DVD is giving me a headache.

EDIT: dgindex says that the entire thing is around 50% film... so maybe I need to make a Variable Frame Rate file (mkv with timecodes)? Again, anyone who could download the sample and take a look, or direct me to a guide on hybrid VFR dvd ripping would be great.

Have you fixed your "stairstepping" issues yet? If not run a search, i am pretty sure Soulhunter made a script that can take care of aliasing in Anime.

I think it's called AAA or something. Mind you, it is supposed to be very slow.
