Deinterlacing Nightmare - Need help!!

[Nausiated]

Hi! So I've been fighting to get this video deinterlaced properly. Here's a link to the video on my Google Drive:

This is what I am working with to the best of my knowledge:

https://drive.google.com/file/d/13JO-p_oCHVPDXZZqQsL2Wu3KS0mVMVea/view?usp=drive_link

The video source is a Laserdisc source. I pulled the raw data via the Domesday Duplicator and ran it through the ld-decode suite.
I've put it through its paces with all of the deinterlacers that are available in a standard StaxRip installation in both Avisynth and Vapoursynth. I can usually eliminate the combing but I get "frame ghosting". Maybe it has something to do with the video being telecined and some issues with it going from 24 fps to 29.97. I don't really know because finding a straight answer to trouble shoot this has led me down so many frustrating rabbit holes and dead ends. I honestly don't even f-ing know anymore.

I have spent hours and hours trying to suss this out am getting nowhere. This side of things I am not very well versed in. I am a video editing person. The whole restoration side of things is not really my bag. I am just exhausted and fed up because I keep hitting brick walls and available information is all so scattershot that it is hard finding a solution that works.

Could somebody please take a look at this video and help me figure out how to deal with this ghosting issue? Is it even a fixable problem or have I been beating my head against the wall to try and undo something that is burnt into the original video? Like I'm about ready to put my fist through my computer monitor at this point.

I'd like to stick with StaxRip because it is the restoration program that I have grudgingly figured out how to use and installing, troubleshooting, and figuring out how to use another piece of software is going to be another point of aggravation for me. I don't have the time to learn something brand new on my timetable. Also, if you're going to recommend filters on StaxRip that are not preloaded, point me to where to download these filters and how to properly load them into StaxRip.

Like I am frustrated to a very large degree and really wish there was some kind of practical solution. Maybe I don't know where to look, I don't know, but my god, this is just so draining of my time and energy I just want a simpleish solution so I can move forward.

Anyway, any help that can be provided would be greatly appreciated.

Google Drive's reporting that file is 20GB. I doubt you'll get many takers.

Trim it down to a minute or so with Losslesscut and then post. That will give us enough to check the interlacing pattern.

Also, have a look at my beta blurb on Interlacing. You'll probably find it has one of the standard telecine patterns that can be easily returned to the original with a basic AVISynth script (perhaps Staxrip will have the required option as well).

@Alwyn: Your description of "3:3 pulldown which is "technically 2:2:3:2:3" and "4:2" Pulldown is doubtful IMO, as you can veryify with a closer look to your short "33pulldown.mkv" example which is not just "3:3 PPPIII" (for better evidence you may have to analyze a longer clip though): It starts with PPPPII and the changes to PPPIII and then again PPPPII .....

Actually 2:2:3:2:3 (or a cyclic variant of it, depending how one starts) which when used for converting 25p (24.975) to 30i (29.97i) normally gives repetitive PPPPII patterns, but can also give alternating long pattern sequences of PPPIII (12x) and PPPPII (13x) when watching as frames on a progressive monitor. I think it depends on conversion workflow details. Inverse Telecine is the same procedure for both though.

Edit:
Also, you may want to include the 2:3:3:2 pulldown (aka "Advanced Pulldown") which is typically used by DV camcorders to produce 29.97fps from 24fps. Viewing it as frames (i.e. without deinterlacing) you will see a repeating pattern of 4 progressive frames (no combing) followed by one interlaced frame (with combing - or jaggies as you call it), or in your terminology PPPPI. To reduce that to 24p you want to discard the interlaced frame from each group of 5 frames.

(I think your Telecine/Pulldown section needs a revision).

QTGMC()
Cdeblend(omode=2,xr=4,yr=4)

Seems to, replace the blends by replacing them with adjacent frames just fine. (denoising in QTGMC will improve the result)
I then would recommend using sRestore to remove duplicate frames,...
(seems like original fps might be, 18000/1001 fps)
No clue whether C_deblend comes with StaxRip,...

This was exactly what I was looking for! VDub worked just as you said it would! Thank you so much!

Cheers @Nausiated.

@Sharc, don't worry, my left-click finger was shaking with worry when I clicked to post that link, wondering what reaction I'd get!

I'll certainly study your comments, thanks. I'm thinking I might do away with the "X:Y:XX:Y Pulldown" terms because they are irrelevant to the problem and the solution and, I think, probably confuse the general population who just want to get rid of the jaggies.

A Work In Progress...

You have a field blended PAL to NTSC conversion. You need QTGMC().SRestore().

Understood.
I would also remove the "33pulldown.mkv" example, because it conflicts with your description
- it shows the PPPIII pattern in the middle of the clip only. Start and end sections are PPPPII
- 3:3 pulldown would build 3 fields of the first frame and 3 fields of the second frame, joined correctly to preseve the field order. Framerate woud increase by 3/2, so 25p->75i or 24p->72i which is not what one usually needs for PAL->NTSC framerate conversion or telecine.

Sorry for not staying on topic of the OP's original issue which was solved with jagabo's post#8.
