Decomb Fieldorder

[DvdKhl]

After I encoded a series from DVD to XviD and wanted to watch it,
I noticed stutteringing playback, like if I had set up the fieldorder wrong in Decomb.
But I followed the tutorial:

----------------------------------------
AviSource("your_clip.avi")
AssumeTFF().SeparateFields()
--
If the motion is correct with AssumeTFF().SeparateFields(),
then your field order is top field first and you must set order=1.
If the motion is incorrect, then your field order is bottom field first and you must set order=0.
If you are want to double check things, you can use AssumeBFF.SeparateFields() to check correct operation for bottom field first.
----------------------------------------

I did that and with it I could determine the fieldorder (order=1),
but when I load it in VDub you can sometimes see frames "doubled".
When I change the fieldorder (order=0) it works nicely.
Doesn't the method to determine the frameorder work anymore?
If not is there another way to get the order besides looking the hole video in VDub after "doubled" frames?

Sorce is a PAL DVD and I used the latest Decomb 5.21 package and DGMPGDec 1.0.10

AVS Files:

To test the frameorder after the tutorial:

MPEG2Source("D:\Encoding\Vobs\4.d2v",idct=6,ipp=true)
AssumeTFF().SeparateFields()
(Viewing the video shows me I have to set order=1 because the motion is correct)


This is my encoding script and the motion is sometimes not correct. Only if I set order=0.

MPEG2Source("D:\Encoding\Vobs\4.d2v",idct=6,ipp=true)
Telecide(order=1,guide=2)
TemporalSoften(4,4,0,15,2)
LanczosResize(544,400,8,4,706,568)


I have uploaded a Vob (10.6MB) file that should show the problem, an avi (XviD 702KB) with the wrong fieldorder and some avs Files

The fieldorder is TFF. This is a crappy field-blended clip that is for all practical purposes like pure interlaced material. You can't usefully apply Telecide() to it.

Funny. I made the same mistake when I tried to back up my ST:TNG DVDs. ;) http://neuron2.net/ipw-web/bulletin/bb/viewtopic.php?t=69

the startrek TBG DVDs seem to suffer another problem.

they are converted from NTSC to PAL using PAL-Speedup.
this means: FILM parts are Progressive-PAL on that DVD,
and Video (60i) and Effects (30p) are fieldblended-PAL.

BUT: sometimes blending occurs even on FILM parts of TNG.
this seems to occur only between two effect/video parts.

I've seen a sample, where only

kernelbob().selecteven() or kernelbob().selectodd()

was needed to knock out those blends.

this means, the ST:TNG DVD need individual treatment for individual frame ranges, to get a High Quality Progressive video.

Progressive -> leave Untouched
blended Progressive -> method above ^
true fieldblended -> blenddeinterlacing

Yes, I noticed that too. However, the sample from "Buffy" above seems to be the same beast. "The X-Files" suffer from the same problem as well. I stopped buying TV-Series on DVD as PAL-versions because of that. I'm replacing them with the Region 1 versions. They are difficult to process as well, but at least I don't have to worry about blended fields anymore.
