Transparent Lines Problem

[Madaqua]

Good evening.
Does anyone know, how to fix such problem? I have several scenes with transparent vertical lines. can't fix with any denoisers or defreq.

Thanks in advance.

Tried DeScratch ?

[Madaqua]

Yes, doesnt't help, DeScratch don't see this lines.

Tried to down your sample, but it will not download, at 8 MB very small clip or maybe image, if image then you need to maybe upload a shortish clip for those that can help.
Another file host might be a good idea. [MediaFire is popular].

Here (https://www.mediafire.com/file/bkrdi1meni6dm2w/sample.mp4/file) is the sample. What i need to solve: the static objects moves (stones on the ground for example). I guess it's because of this layer of transparent lines..

I got terrible eyes, but looks to me like some kind of ghosting from adjacent frames.
Also, there is a horizontal white line about 10 or 12 percent from top [mostly at RHS].
I'm not seeing any VERTICAL lines, just what looks like the stones outlines from adjacent frames or maybe several frames away,
or even maybe spatially displaced from same frame.

No idea what to do with that.

EDIT: Maybe a clip with less 'lumpy' stuff ie stones, some kind of uniform scene with some [EDIT: ideally sharp] rectangular structures, so could maybe establish where the lines are coming from,
your current sample is way too 'busy' to tell.

With this I see the noise in Luma, and I think also in U, but not V, maybe better eyes can see in V.

I see the line. It is quite clear. It waves back and forth like it is an actual rope hanging in the foreground in the scene. There are various software programs designed to remove such things, but they usually are tough to learn and cost money. The term you are looking for, to find the right program, is "rotoscoping." You can Google that word and "remove" and "video" and you'll find lots of help.

Here is a tutorial on how to do remove your line in After Effects:

Use rotoscoping to cut moving objects from video (https://www.adobe.com/products/aftereffects/rotoscoping.html)

There is no vertical line

John, I think that is a rope, also a black one too, hanging from the mast attached to the armoured car.
The man in the background even trips over it and bends to adjust the guy rope. [EDIT: OK, he dont trip, but he notices its loose and adjusts it]

EDIT: Is/are the ropes the lines you are seeing ???

EDIT: And there is at least one other loose whispy string dangling from the mast/aerial and dancing in the breeze.

[johnmeyer]

John, I think that is a rope, also a black one too, hanging from the mast attached to the armoured car.I agree, but it is the only thing I could see which matched the OP's description.

Also, I just re-ran the clip, and it looks like there is also a very thin dark line hanging from the back of one of the actors. This could be a wire attached to a stunt man which they forgot to rotoscope out of the scene prior to release. You see these wires all the time when the studio releases the "making of" video showing behind-the-scenes video of stunt people doing impossible things, but protected from disaster by a wire which keeps them from hitting the ground. If this video was from some pre-release, or if it is a really low-budget film, they may have forgotten or been too lazy or too rushed to complete the post-production properly.

[StainlessS]

Nope, they are guy ropes helping support the aerial/mast on back of armoured car.

Yep, the fella in back notices the peg has come out of the ground and starts hammering it back into the ground
.

EDIT: There are also several more 'hints' of strings/ropes angled down to the left of the mast, cant really pick them out from still frame, only when movement.

EDIT: I'm getting this from the mono script I posted, separated channels.

Can you test with mvtools2
super = MSuper(pel=2, sharp=1)
backward_vec2 = MAnalyse(super, isb = true, delta = 2, overlap=4)
backward_vec1 = MAnalyse(super, isb = true, delta = 1, overlap=4)
forward_vec1 = MAnalyse(super, isb = false, delta = 1, overlap=4)
forward_vec2 = MAnalyse(super, isb = false, delta = 2, overlap=4)
MDegrain2(super, backward_vec1,forward_vec1,backward_vec2,forward_vec2,thSAD=400)

guys, heres (https://www.mediafire.com/view/82adr8mf1l9vbco/sample_1.png/file) the screenshot with this lines. do anybody see??

[Madaqua]

kedautinh12, ive tested with mvtools hundred times, it doesn't help.

Looks to be shimmering, you can try QTGMC with the deshimmer function only.

QTGMC( Preset="Slower", InputType=1 )

[johnmeyer]

OK, now I definitely see what you're talking about. Your original description of "transparent vertical lines" was not completely accurate and that is what threw me. The artifact actually shows more strongly as moving horizontal "lines" that are especially apparent under the tank. There are probably vertical lines as well. Both are the result of either very poor compression, or poorly-done scaling. Was the original a 4K video?

I've not used QTGMC's deshimmer function, but that's certainly worth a try. I just tried almost ten different filters, but couldn't find anything that would eliminate the problem. I would guess that it will take some sort of motion-compensated convolution filter, or something like that, which will average both adjacent frames and adjacent pixels.

[StainlessS]

OK, I too can now see those lines.
But I find the weird horizontal rippley lines over the stones more obvious (I thought it might be ghosts of the stones or even from the river water above, but it aint).

The artifact actually shows more strongly as moving horizontal "lines" that are especially apparent under the tank.
I think we are talking bout same thing. [rippley lines that sort of fall like snow]

You got some well peculiar noise in that clip.

Guys, thank you very much! One of my main problem has solved now!

[kedautinh12]

Guys, thank you very much! One of my main problem has solved now!

What scripts you use??

[Madaqua]

kinda this:

turnleft()
QTGMC(Preset="Slower", InputType=1)
turnright()
QTGMC(Preset="Slower", InputType=1)
