X-Files Region2 interlacing problem....

[thepi314]

Hi!
I wanna encode XF seasons in XVid/AC3, but I get awfull interlacing lines on some sequences (not always !)... :-(

I already tried out several plugs for VDubMod... but no good results yet ! :-(

Anyone having an idea ?
Thx in advance,

First of all, are you even using a deinterlacer?

Second, check: http://forum.doom9.org/showthread.php?s=&threadid=40555&highlight=xfiles where it is quite throughly discussed.

[thepi314]

Hi !
So first, o' course : I'm using Shaun Faulds's "Dynamic Field Order Correction" filter...

And second, I've been thru this thread already, tried some of the filter, but I didn't find anythin' truly convincing :-(
And they all are using Gordian Knot, I'm not ! *blink*

So how are you encoding? Are you making a pseudo avi through Flask or something like that?

Hardly any filters are made for VirtualDub any more, have you considered switching to Avisynth (in which case you'll certainly find that thread useful)?

[thepi314]

I was using DVD2AVI to build a pseudo-avi then putting it thru VDub...

Now I'm using VDubMod which directly supports VOB file as input !

So you think I should switch to AviSynth ?

Definitely. It's what pretty much everyone uses and you'll be able to use nice filters like decomb (which should solve your problem) and convolution 3d and many others. Plus it should be faster, though I'm not certain of the speed of DVD2AVI.

Edit: You'll probably wanna use Gordian Knot to help you use Avisynth.

Hello,
after some testing and help from some nice people here :) I am quite happy with the results.
Telecide(post=false) gets rid of the mouse teeth.
So I go for Telecide(guide=2)

My settings for the x-files,PAL, resize 640x480
GKnot .27,DivX 5.02 two pass, b-frames, GMC. Bitrate between 1100-1600 kbits, so far, depending on comp check 65-80%
The compressibility :) of each episode differs quite a lot.
I end up with files (video only) from 368 to 514 MB.

Might be useful for you, thepi314.

BTW, I am no professional in DIVXing at all.:D
Just my 2 cents.

manono's excellent info for Hybrids:
AviSynth 2.5 has come out and Decomb for AviSynth 2.5 has another mode to handle Hybrids (a mode not available in the version for AviSynth 2.07, unfortunately). Whereas before, Decomb's Mode=1 added a blended frame to the film portions and kept everything at 29.97fps, there is now a Mode=3, which blends the 29.97fps material and gives you back a 23.976fps video.

From my thread:
http://forum.doom9.org/showthread.php?s=&postid=257602#post257602

You may want to try this and let us know how it works.

[thepi314]

Wooooow !!!
Hobojobo, big thx for your example ! Helped me a lot ==> Picture is now perfect !!!

Also thx to the ppl who tooks time to answer me here, and finally thx to the ppl who managed to program all this :-)

.:Pi314#

[thepi314]

Well .. close to be perfect ! :-(
Some camera panning looks awfull - for instance, Episode 2x03 between 9:25 and 9:40 !

@jfcarbel
So, I'm trying AviSynth 2.5 now... Will feedback !

.:Pi314#

[thepi314]

Well, nothin' seems to solve the camera panning problem... maybe if you play with the decom's parameters, you migth get somewhere, but I admit, I don't really know what I'm doin' :-D

So if anybody wants to help... plz ?

[Guest]

Post your script.

Is your material PAL?

[thepi314]

Well, I did use Hobojobo's script previously posted... I could post the others 200 scripts I must have tried yesterday, but that would be pointless...

And yes, it's a PAL source ;-(

Thanks in advance for any help!

You said panning looks awful. What does that mean specifically?

[thepi314]

Well, on some 'short' camera panning, the scenes looks jumpy like the framerate was divided or somethin'...

I check on the particular scene I posted earlier (2x03 between 9:25 and 9:40) while the camera "jumps", the decomb filters shows only combed pictures - I used show=true on telecide() - while on normal scenes it constantly switch between clean" and combed pictures.
Don't know if that might help or anythin' ....

Did you try also encode it without GMC in DivX settings? Since I am not sure this is the same kind of panning, but at least for me this can produce such effects. Without GMC everything looks pretty good. Haven't tried with X-files thought.

[thepi314]

Well, I had such problems with DivX and GMC on the 1st season
Now I switch to XviD for the 2nd... (!)

For check that it wasn't directly the encoder, I disable the interlacing filter and encode the particular scene with the same options => movement is perfect !

.:Pi314#

[thepi314]

Well... Still nothing ? :-(

I was wondering, guide=3 of Telecide() is made for manage hybrid NTSC, right ? Would it work with hybrid PAL as well or ... ?

.:Pi314#

Edit: I meant hybrid NTSC which was converted to PAL ?

[Guest]

No it works only for NTSC.

Make available for download a VOB fragment that shows your problem and I will be happy to look at it.

[thepi314]

Now I might sound like a newbee but .... how to cut a vob properly ?

Well, I meant better way than VobSplit which works with offsets in bytes !!!! .. Anyway...

Best I could do, compressed with WinRAR 3.1:

I found some time to have a look at it. You have the dreaded blended fields in a PAL clip. But most of the bad blends are in the odd fields (at least in this VOB fragment). So this script works better than default behavior:

loadplugin("d:\avisynthplugins\mpeg2dec3.dll")
loadplugin("d:\don\programming\c++\avisynth\decomb\release\decomb.dll")
mpeg2source("clip.d2v")
Tweak(sat=1.2,cont=1.4,bright=20)
Telecide(threshold=25,blend=false,reverse=true)Encode it in DivX and watch it at normal speed. The pans look much better than without the reverse=true option.

I can't think of any way to improve on this.

[Valky]

This is little bit off topic, but since I have had also problems to find good and simple vob-cutting tool..so now there really is!!

ChopperXP! It can't come any easier with that. Preview window and also estimated filesize..this is really all I ever need. I got really frustfrated with these previous tools that were on doom9 download site. I am newbie, but still..this software is absolutely fabulous.

[Guest]

@Valky

Why don't you submit it for inclusion on the doom9 download page?

[Valky]

öö..cause I thought that doom will decise what he puts there..and I guess I forgot to mention that I saw it on dooms news-page :(

But like I said..this is really simple and easy-to-use tool :)

Maybe someone with more power than I can give a hint to doom if it isn't there already..

Indeed it looks better... on that particular scene. Not on a full episodes :-(

So,I'll keep the old settings, thx anyway for your time and keep up the good work :-)
