Yet another ghosting problem

[jeebs10]

I've been trying for a few days to find a solution to my ghosting issue with no luck. Read tons of posts about ghosting here and at doom9 and tried various fixes, but i can't figure it out. I figured maybe if someone knowledgeable actually sees the clip they will know right away how to fix it.

The source is an anime DVD from the 90s, which apparently have frequent issues. Sample clip is raw mpeg video from dvd in mkv container. The source will deinterlace fine (sample is untouched though), but i can't get rid of the ghosting. using separatefields() reveals the ghosting to be present in the source, so i'm assuming some sort of blending was employed before interlacing for some reason. as far as i can tell it is not chroma ghosting. i read about pal to ntsc conversions and such, but i can't figure out how to tell if that's what the issue is here. i have tried srestore() with no luck, but thought maybe i am just doing it wrong. i generally use vs and not avs, but have the ability to use avs if i have to. the source is also VFR, which i thought might have something to do with the trouble that i'm having. i'm relatively new to attempting to restore videos, but i can usually figure it out with enough googling. this one has me frustrated, hence my first time asking for assistance.

Sample clip

thank you in advance to anyone that can help!

The next time you upload a sample, please extract it from the DVD as an M2V using DGIndex. By uploading an MKV you've forced anyone willing to help to go through the extra step of demuxing the video. MKVs can't be indexed properly in DGIndex.

It's field blended as you discovered. It's an unusual one in that it's not a PAL to NTSC conversion. It was converted from film. Only the worst fly-by-night companies do that. Anyway, the fix is easy:

Yadif(Mode=1)# or the better QTGMC or other bobber of your choice.
Srestore(Frate=23.976)

...the source is also VFR...

All NTSC DVDs output 29.97fps. In that sense it's not VFR. Yes, there are differing framerates within the video, but it was created at and meant to be played at 23.976fps (24fps) so those framerates are fractions of 24fps, such as 24, 12 or 8fps. It has nothing to do with the problem.

I apologize. Like i said, i'm pretty new to this. i will make sure to do so in the future!

I was having trouble reproducing your results with this. in fact, i had already tried this with both yadif2mod and qtgmc before even posting on here. but i think i may have come across the answer to my problem using the first part of your post: MKVs can't be indexed properly in DGIndex.

i'm not lazy, but i try to make things as easy as possible on myself. so, i have been using MakeMKV to create nice neat files that are already trimmed and easy to work with from my DVDs and BDs. Then, I (typically) use staxrip to import as a frontend to vs/avs+ and also use for final encoding. well, staxrip uses ffms2 to index and frameserve after demuxing the mkv. when i directly work with the vob file, indexing is performed by dgindex and served to vs via d2vsource. this produces far superior results in terms of eliminating the blending with the supplied script versus the mkv method. i still have some very minor issues showing up, but having just discovered this problem, i am sure that with some more tinkering i will be able to figure it out. i feel silly now, as it seems that the bulk of my problem was self-created by using improper methods

this is an example of how small the blending has become working with vob and srestore:

I didn't take any screenshots of it using the previous method, but let's just say it wasn't really much better after filtering than before. thank you so much for your quick reply and insights. this was starting to drive me crazy. i apologize for not taking more time to learn about proper methods for working with dvd's before posting. i just assumed it would all be the same. i'm going to spend some time learning about more about dgindex and proper methods for working with dvds.

hmm after working for about 6 hours, there just seems to be a few things that aren't able to be fixed (at least with my limited knowledge).

maybe just a temporal denoise to help what it can and call it a day? honestly, the small amount of blending that remains isn't noticeable at all when viewed in real-time. i guess it just kind of bugs me because i know it's there, even if i can't see it but at least it's 100x better now. thank you again manono!

This just looks like standard 80's and 90's Japanese telecine. They're all blendy as hell.

I couldn't quite tell whether or not you've begun decrypting correctly. Use a real decrypter. That DVD can probably be decrypted using DVDDecrypter. If set up in File Mode (the default, I believe), you'll get the complete DVD with VOBs, IFOs and BUPs onto your hard drive. Then use DGIndex on whatever you like. If you need to separate out episodes, in case they don't have their own separate VOBs, then use PGCDemux to do that.

I don't use MakeMKV for decrypting. I use AnyDVD HD. I used to use DVDShrink with compression turned off to create ISOs, but I haven't used it in a couple years. AnyDVD works beautifully on my BD and DVD so I've stuck with it. I rip my BDs to files, but have still been ripping my DVDs to ISO (habits, i suppose?). But I can mount the ISO backup and rip the files using AnyDVD, which is what I attempted when working with the VOB and DGIndex. I'm not sure why the results were so much better this way, but they were. According to the AVS wiki, ffms2 can have some issues with frame orders in interlaced content, so i suspect this to be the issue i was having.

Tell me, were your results any better than mine? Or was minor blending still present? I'm just curious because if it's possible to completely remove, I will keep messing with it until i get my setup correct.

ISO? Why? Just decrypt the files to the hard drive the first time.

Yes, I see that crap as well. I don't know how to get rid of it. Chalk it up to having lousy DVDs. There's just too much blending to remove all of it.

That was the answer i was slowly arriving at. But thank you once again for your assistance! The information i have learned from you is far more valuable than fixing just one video, as my flawed work flow would almost certainly have created the same repeated headache time and time again

[killerteengohan]

QTGMC(preset="slow", matchpreset="slow", matchpreset2="slow", fpsdivisor=2, sourcematch=3, sharpness=0.1)
srestore(frate=23.976)

That's about all you can do about it that I can think of. The source is an old DVD and some of them you cant get around all of it, but you can reduce the amount of it. QTGMC will do a much better job than Yadif, and look better overall as well.

If your using a derainbow filter, those can cause similar blending issues. Turn the strength down or try another one if you are using a derainbow filter.

Good luck!
