Proper deinterlacing

[Xpenguin17]

For the first time in 3 years, I'm ripping a movie off a DVD because no Blu-ray was released and is not likely to ever be released. So I'm not really adept with the best quality deinterlacing. I normally use TempGauss but in this case it was pointless because it's an old anime that normally has doubled frames every here and there so the "restored" 59.94 framerate was just even more double frames and no real interpolated frames.

I decimated the whole video by half, so I now had progressive 29.97 fps but it still had duplicate frames so I dropped every 5th frame and ended up with 23.976. This eliminated that problem, but the video still looks wrong. It's jittery but only on parts of the frame that moved and only some of the time. Something tells me that this is not how a non-dumbass deinterlaces his rips.

Ordinarily you wouldn't deinterlace, and certainly not the way you did. Usually you IVTC. But to be sure of how to treat it we'd need a small sample, 10 seconds or so showing steady movement, especially a section with as few duplicate frames as possible.

[Xpenguin17]

I tried IVTC via MeGUI and the resulting quality sucked ass (not to mention it didn't properly deinterlace either.) What would people who know what they are doing do?

People who know what they're doing don't rely on MeGUI to analyze their sources and to provide them with a proper script. Learn to analyze with your own eyes and to develop your own scripts.

As requested before, post a sample. Cut a small sample using DGIndex and upload it somewhere like MediaFire or Sendspace.

Yeah, I would, except that I know shit about deinterlacing.

Am afraid I can't do that. I bought this rare DVD from the only store that sells it only hours before I produced that post. I'm not risking the inconveniences of it being traced to this ID if it starts circulating on the net.

You'll have to suggest another way to be useful. Get me a video with the following pattern: PPPIIPPPIIPPPII where P stands for progressive frame.

I suspect that you have just made most people here unwilling to be "useful" to you!

Posting a 10 second sample would be "fair use".

If your video is a clean "PPPIIPPPIIPPPII..." then TFM().TDecimate() should work. But it may have field blending if it went through a PAL to NTSC conversion. And anime is often a mix of 60 unique fields per second, 30p frames per second, 24p frames per second with 3:2 pulldown, and other stuff. Old anime (before the use of computers for animation) is more likely to be only 24p film with 3:2 pulldown though.

[manono]

The PPPII pattern describes hard telecine and an IVTC usually fixes that.

I'm not risking the inconveniences of it being traced to this ID if it starts circulating on the net.

That's just silly. If there are places where the IVTC doesn't work, then the only way anyone can help is for you to show us a sample from the source that, when IVTC'd, doesn't 'properly deinterlace'.

As for the quality being bad after an IVTC, I'd say that's more a function of your encoder settings than anything to do with the IVTC. And I hope when you said you tried an IVTC you weren't referring to what you described in your first post in this thread which was anything but. Anyway, if you can't or won't produce samples, then there's nothing anyone can do to help. Good luck.

I'm pretty sure there's at least one tiny segment of the movie that's, well, clean...

Seriously though, I too would love to see a sample if possible - sounds like an interesting problem.

[Xpenguin17]

I'm not worried about being sued... I'm not selling anything. I'm not having the source of this leak traced to this net ID which I basically use everywhere, and I don't want yet even more ebay-camping mental fucks following every god damn post I make in all the other 20 sites I got an account on.

If your video is a clean "PPPIIPPPIIPPPII..."

Actually, I just realized it isn't. Sometimes 2 interlaced frames + 3 partly-interlaced frames appear. This video is supposed to be PAL as it isn't produced in the US, so you are probably right about it going thru the NTSC conversion. TFM Decimate worked but it still had the blend-wobbling on moving objects as TempGauss not to mention having shittier detail-retention than TG.

As for the quality being bad after an IVTC, I'd say that's more a function of your encoder settings than anything to do with the IVTC.

What encoder? I have used IVTC on the video directly from the DVD. The lines and edges are all jagged and it only half-decombs the interlaced parts.

[manono]

Yeah, but now you've changed your story. Originally it was PPPII and now you're seeing different patterns that possibly point to a bad PAL2NTSC standards conversion with blended fields. But without a sample I guess we'll never know what you have and you'll never know how to make a proper script for it.

[Xpenguin17]

Originally I only looked at 20 frames, I looked at 100 now.

Tell you what, you send me a sample and maybe it'll help me decide if the DVD or the app is the culprit.

[jagabo]

He'd have to send you dozens of samples to cover all the bases. Not practical.

dude, what exactly is your problem? these people have been trying to help you and all you've done is give them an attitude and give nonsensical reasons as to why you can't upload a ten second clip for analysis.

how about you solve your own problems and leave everyone alone?

Why dozens? I only need one.

Blow me fuckrat, I could release this rare movie out there with substandard quality or just change my mind completely, and let you buy your own (if even available) from eBay for like $400 if that suits you better.

a) i don't like baby food, if that ever changes i'll let you know, pimple dick.

b) you're not doing me any favors, i couldn't care less about whatever movie you're talking about and i couldn't care less about you.

c) you shouldn't be "releasing" the movie, you don't own the copyright to it, what you are planning on doing is classified as "piracy" and such topics are against this forums rules. sticking the movie up your ass is not against the rules, so, hint hint.

p.s. those that believe in a cause and feel like "releasing" a movie usually just release the iso and let people burn that to a dvd and be done with it, but again such things are against this forums rules, so your ass, your dvd, you might want to get started.

Oh you like pimpled dongs do you? I can't accommodate you in that department, but I can draw dots with a red marker if you want?

b) you're not doing me any favors, i couldn't care less about whatever movie you're talking about and i couldn't care less about you.

Very good, you've realized that none of this or what I do concerns you. Next step: keep the **** out of my thread when it doesn't.

Releasing? What? I dunno what you talkin' about, mang :O

You mean upload 4.7 gigs over and over again? I don't have to give shit away at all, bro. When I do, I will probably, like 90% of rippers, make it as least expensive on my end as possible. You're delusional if you think I have any greater obligation.

Either way, I've remedied the problem.

Good night.

[TimA-C]

Pillock!

[greymalkin]

stay classy!

[deadrats]

Either way, I've remedied the problem.

so you decided to go with the "dvd up your ass" approach? excellent, glad to hear it.

and because you're such a steaming pile of monkey spunk i hope the mpaa traces the release back to you and sues you for the maximum allowed by law.

normally i fully support file sharing, but in your case, you're a douche.

[Calidore]

Is this thread still going just so people can toss out juvenile insults? I don't know the others, but deadrats, this is beneath you. May I suggest dignity over getting the last word?

Best,

Calidore

[TimA-C]

I think deadrats was actually showing quite a bit of restraint, but I think this thread is probably dead now.
