my Deinterlacing is jerky

Hi!

I'm trying to deinterlace Dvd Anime , sample video without sound could be found here :
http://dl.free.fr/bS0HkWiQ3 (ddl)
or http://www.megaupload.com/?d=IBMLCPCF

or http://www.mirorii.com/fichier/54/42...muxed-m2v.html


I'm trying do deinterlace with this avisynth script :
Code:
d2vpath = "i:\frps\01.d2v"

V = mpeg2source(d2vpath)
interp = V.separatefields().eedi2(field=-2)
deint = V.tdeint(mode=2,edeint=interp)
V=V.tfm(d2v=d2vpath,clip2=deint)
V=V.crop( 0, 0, 0, 0)

 A= DirectShowSource("i:\frps\VTS_01_1 Ta0 48K 16bit 2ch.wav") # adjust fps if necessary

AudioDub(V, A)
Problem :

My video has an excelent quality, but the video is litle jerky and my example contains a passage with traveling who show this problem.

I'm litle noob, so could you give me a way to obtain the same quality and without this jerky thing

I tried YadifMod (saw on http://forum.doom9.org/archive/index.php/t-154726.html), but quality seems lower and i cant make work the mod withe same fps ( i obtain 59 fps lol)

Content is not interlaced, so don't deinterlace it


MPEG2Source()
AssumeTFF()
TFM()
TDecimate()

hi, ok i tested your code, and it worked lik a charm (faster lol). I got some bugs at some place i presume it comes from the original stream.

Few questions :

1) Why i saw it like interlaced video? is it telecine thing?
2) is there any option to increase quality or is it pointless? ("mode=" for example?)

thx.

What bugs? can you be more descriptive?

Yes, telecine

If it's simple telecine, no.

All you are doing is recovering the original progressive 23.976 FPS stream.

If there are cadence breaks or some other non standard things going on in other sections, post a sample
