Fix ghost effect in a bad ntsc to pal converted original DVD

[Talayero]

Hi,

I bought an american movie, Stranger's Kiss, and now I realize that it has that ghost effect when the actors or the camera move laterally. It doesn't ruin the film but it annoys me a lot.

I think they have botched the ntsc to pal conversion.

I know there's a script to see if the fields are totally blended and you can't fix it, or on the contrary, there's still some hope to amend the thing. For the moment I used

Could someone please to help me on this.

Thanks in advance

PS: This is what Bitrate Viewer says about my dvd. I don't know if that's useful:
Resolution 720 x 576
Framerate: 25.00
Pic. structure: Frame
Field topfirst: Yes
DCT type: Field
Quantscale: Nonlinear
Scan type: Alternate
Frame type: Interlaced

Thank you.

For the moment, I don't know how to start the fixing process.

In that thread you pointed out, the person who posted it tells about a problem with a movie that "was converted to NTSC from a PAL master". Is it the same problem as mine? Probably, but I don't know how to apply that.

Sorry, but it sounds complicated to me.

I can't figure out which specifc script I could use to get rid of that ghost effect in my PAL dvd.

It's a PAL DVD, Soopafresh, and therefore he won't be able to use RePAL. He'll have to use a different unblender, such as Restore24, CDeblend, MRestore, or others.

As 45tripp suggests, a sample will help us a lot.

Are you now Avisynth experienced, Talayero? Fixing this isn't going to be easy.

A sample:

Yes, manono, I have familiarity with Avisynth.
One problem I have it's now and then I forget the scripts I've used. For instance, I'd like to remember the script that duplicates the frames, 50 instead of 25 fps, and that can be used to see if the fields are blended or not

Either just add SeparateFields() to the script, or, to make it more easily seen, add in a smart bobber, such as Yadif(Order=1,Mode=1) or LeakKernelBob(Order=1)

It's blended. The framerate is 24fps. That's partially a guess, as there's not enough there to be 100% sure, but based on past experience with these things, it's really 24fps. I had my best luck unblending it and returning it to 24fps with:

Yadif(Order=1,Mode=1)#or any other smart bobber
CDeblend()
TDecimate(CycleR=26,Cycle=50,Mode=1)

Here is a sample a bit longer, just in case:

Well, my familiarity with avisynth seems to be limited.

Is this the script I shoud use?:

LoadPlugin("dgdecode.dll")
Mpeg2Source("stranger kiss.d2v")
Yadif(Order=1,Mode=1)#or any other smart bobber
CDeblend()
TDecimate(CycleR=26,Cycle=50,Mode=1)

I suposse also I need to have Yadif, CDeblend and TDecimate as plugins of Avisynth.

Two more question, just to learn a bit:
Did you use that separatefields script to know that it's blended?
and how could yo know that it's 24fps.

[manono]

Yadif has a .dll. And you use LoadCPlugin for Yadif, and not just LoadPlugin. CDeblend is a function, and is included in the R_pack (search Doom9), and when being used you have to load a bunch of other stuff. TDecimate is part of TIVTC. I didn't download the new file you put up.

And that's why I asked if you've gained a lot of AviSynth experience.

To determine it was blended, I put on Yadif(Order=1,Mode=1) alone. Believe me, with a good sample like that, it's very easy to see it's blended when stepping through it in VDubMod. You'll see a lot of double images/ghost images/blended images. How did I determine it was 24fps? I unblended it to 25fps and started looking for duplicate frames.
