Removing horizontal striping artifacts (NOT deinterlacing)

[mukan]

Please see the samples here (8.9 MiB):

source.mkv is a sample from the source video, where you can occasionally see strange horizontal striping artifacts. For example, it's obvious in the head of the pigeon character, and a little more faint but still visible on the body of the brown bear character

cleaned.mkv is a downscaled version of the video (encoded by someone else) with said artifacts removed or at least toned down. I also included a couple of screenshots of frames from both videos for easier comparison

How can I remove these artifacts? I'd be pretty happy if I can get it to the point where it looks like the "cleaned" video.

Any kind of masked smoother will eat that for lunch. For example, my MSmooth (a spatial smoother) looks great on it:

msmooth(chroma=true,strength=6,threshold=5) #tweak as needed

I can release a 64 bit build of msmooth if you want it.

People like StainlessS will surely chime in with other suitable smoothers.

Not ruddy likely. Also MSmooth and MSharpen were once amongst my very favourite smoother/sharpeners,
"They refresh the parts other smoothers/sharpeners cannot reach" [mod of Heineken slogan].
Dont think source was ever given (for at least one of them).
64 bit build would be much appreciated by many, methinks.

I thought you'd give mukan a script, as you are the script Meistro!

I'll make a 64-bit version right now and link it here. Both MSmooth and MSharpen source are linked at my website.

I like Heineken too. It's close to the top for skunky beers. ;)

Good to know, many thanx.

Here is the revised ZIP with a 64-bit executable:

fft3dfilter should be all you need, maybe throws in a edge mask in the mix to protect the line but I think that would be overkill for your source.

Lovely Jubbly.
I already had source for both (and MSharpen in x64), musta got mixed up with something else.
Again thanx :)

[videoh]

Lovely Jubbly. That appears to be an obscure British comedy reference. Can't you enlighten us further about its significance?

Temporal masking with FFT filters as suggested by lansing is also effective here.

Lovely Jubbly:
Superb, excellent, great, etc.
'Lovely Jubbly' was originally an advertising slogan for 'Jubbly', a triangular-shaped frozen orange drink which was popular in the 1950s and 60s.
Later popularised by the character 'Del Boy' in British comedy 'Only fools and Horses'.

I tried to find a translation to USA Pidgin English, unfortunately, no go :)

I often used to have a frozen Jubbly as a kid, a sort of 4 sided triangular pyramid shape (in a sort of waxed paper container[interior polythene], usually[to my knowledge always] orange flavour).
Maybe Wonkey Donkey chimes in on that.

EDIT: Oops, yes, says Orange in above description.

I tried to find a translation to USA Pidgin English USA is well beyond pidgin, but we'll make allowances for you.

Thanks everyone for the replies. Msmooth works perfectly for this

Was it cold where you lived then?

[StainlessS]

Yep, cold enough to freeze my jubblies off.
[A coupla years back, my mother sent me an e-mail (from 'up north', where I come from) with pics of our back garden, two foot of snow and
whole array of about 50, 4 foot long icicles hanging from the roof. Not very impressive if you come from Siberia, but dont often see that in "The Big Smoke".]
