progressive film that looks interlaced

[Subwars]

well as the title says i'm actually trying to do Mean Machine at the moment in PAL format... dvd2avi is telling me it's progressive but i'm seeing interlacing in the picture.... i know that dvd2avi can say a movie is interlaced and it really isn't but can it do the oposite and be telling me it's not interlaced but it truelly is... or is it just my eye's playing tricks on me :D

Check is field order swapped - Video, Field Operation...

[Subwars]

nope i allways have it set to none no matter what

[scharfis_brain]

try telecide(post=false) in an avisynth script

are the interlace-combs gone?

You shouldn't rely on DVD2AVI's labeling. There is no substitute for looking at the video fields (after extracting without FORCE FILM for NTSC). If you have progressive content, it can be mastered normally like this (where every new picture is a letter and upper case is one field, lowercase the other):

A B C D E
a b c d eThat will not look combed. But it can also be mastered as:

A B C D E F
. a b c d eThis will appear combed, even though the progressive frames are still recoverable. It doesn't matter that (say) field a is displayed before or after A, because they are from the same temporal moment (progressive picture).

Therefore, a progressive stream can appear combed. Telecide() will repair that for you as sharfis_brain pointed out.

@subwars: before you try decomb, could you try activate that swap field option in dvd2avi and check if it's still interlaced?

@Doom9
i did that swap field order and it didn't do nothing apart from make the pixels of the preivew look like shit :)

also my source is pal with myself being in australia :D... and you other guys seem to be talking about telecine and all that stuff that you only do with ntsc sources... well thats what i thought anyways.

@neuron2
i know i'm no advanced expert in doing any of this converting and stuff..... but i am geting very good at it i've done over 100 succesfull movies so far... so i've never really needed to get into all of the really advanced side of things.. anyway to your post about looking at the video fields only way i've been able to really do that b4 was just in prievews... ie like in dvd2avi but the way your talking with the codes and stuff... now i've looked at the d2v file in notpad and seen a heap of stuff in there but really don't mean a great deal to me like

so either this is the stuff you were talking about or i should be looking at your code in a different way i don't know... so i'm hoping you could point me in the right direction i can work out most of it by myself i'm definatly no noob when it comes to computers :D just need to be pointed in the right direction and given a few tips.

Hi-

Forget DVD2AVI for a moment. Just make your .d2v as usual (No Field Operation). Your sig says "All Hail Wef And His Wonderfull Work With GKnot", so I'd guess you've had plenty of experience with GKnot. Make your .avs as you usually do for a PAL DVD. Open it up after saving it and find where it says:

#LoadPlugin("Your\Path\To\decomb.dll") #and:

# IVTC
#Telecide().Decimate(5)

Change it so that it says (as scharfis_brain said similarly):

LoadPlugin("Your\Path\To\decomb.dll") #and

# IVTC
Telecide(Guide=2,Post=False)

Then open the Saved .avs in VDub and scroll around to see if the interlacing is gone. If for some reason it crashes, then leave out Guide=2 and try again. I don't know what version of GKnot or Decomb you have.

@subwars There are PAL DVDs with combed fields (this is the result of the 24->25fps transcoding for keeping the original duration). Perhaps you have such a DVD. If so, it's impossible to restore the progressive frame.

I saw one PAL DVD where 25 fps is get without speedup, but it's made with duplicate and blending of one frame (or couple)fields (?). But movement error is still very visible in many scenes.

And I saw one PAL which is fully interlaced (every frame), no any Telecide helped. I think that it's made with video camera, although that movie played in kinos (teatres).
Is it possible that they convert video to film tape, or it is shot with some special equipment?

When you swap fields, you put lines in incorrect spatial positions. It will only help if it is erroneously swapped on the source. That never happens on DVDs but sometimes on old, poor capture cards. Even that is very rare these days.

7 0 55 2 2 2 2 2 2 2 2 2 2 2 2I have explained the d2v file contents in manono's excellent combing tutorial. The 2's mean that there is no MPEG coded 3:2 pulldown. That is all! (They also tell you the field order but that is not germane here.) If it were NTSC, you could not even conclude that it was not film, because it could be "hard" pulled-down (see the tutorial). For PAL, this tells you nothing. I will now explain how to look at the fields (it's also in the tutorial).

Use Avisynth to SeparateFields() and then view the result in VirtualDub. This will make each field into a frame. You may also need ComplementParity() before the separation if it jumps back and forth when viewed. Now, find a high motion part. If every field (now a frame!) shows a new picture, i.e., motion, then it is interlaced content. If you get a new picture every two fields (now two frames!) then it is progressive. This is by far the most direct and reliable way to diagnose the nature of the content. (For progressive content, you'll see that one field of each picture is displaced by a little bit from the other field. That is because the fields represent the odd and even lines of the original progressive frame.) (Also, note that things are different for NTSC; you have to contend with 3:2 pulldown.)

so either this is the stuff you were talking about or i should be looking at your code in a different way i don't know... so i'm hoping you could point me in the right direction i can work out most of it by myself i'm definatly no noob when it comes to computers :D just need to be pointed in the right direction and given a few tips. See above.

sweet thanks neuron2 that helps

EDIT: Turns out manono just meant some earlier versions of Decomb don't support guide=2.
