random interlace

[DvdKhl]

First of all I hope it's the right Forum when it's not I'm sorry!

I'm having hard times with a DVD (PAL) that seems to have interlaced frames, progressive frames, blended fields together
The other problem is that it's random.

so i tried first separatefields.

LoadPlugin("C:\Programme\AviSynth\plugins\MPEG2Dec3.dll")
Mpeg2Source("*.d2v",CPU=0,iPP=True,iDCT=5)
SeparateFields()

then i noticed the order of the fields were wrong (acbd...) so i added swapFields (before separatefields).

after that the order were (aabbcc...)
so this should be odd->even=1 frame
but later in the video it changed even->odd=1 frame
this noticeable because the frame sometimes goes up and down
so there is anywhere a brake in the order (dddeeff...)
is there any way to correct the order?
this is really bugging me

I'm not really an expert on decomb, but here goes.

You might have a movie that has been 24fps -> 25 fps copnverted by inserting a duplicate field every 12 frames - or by blending two fields (let's hope it's the first one)

How does Telecide(guide=2) look?
How does FieldDeinterlace() look?

thank you thank you sh0dan!!!
Now I'm the happiest man on earth :D :D :D
I was a convertion from 24->25 fps
Telecide(guide=2) worked like a charm!!!
I thank both of you for your help and for your quick responses!

Now I'm going to do some batch encodes:)

The fact that Telecide(guide=2) works doesn't necessarily mean 24->25 pulldown is there. If you do have that, however, you'll need Decimate(25) to avoid a little jerk once per second. Examine your frame-reconstructed output without decimating and see if there is one frame duplicate every 25 frames.
