Mosquito Noise Problem

[feisty2]

I have a crappy dvd which has tons of mosquito noise because of the high mpeg2 compression
is there any filter or script to reduce mosquito noise? I tried a lot of denoise filters and scripts,but it seems they mostly work on grain, any script specifically designed for mosquito noise?:thanks:

try > MCTemporalDenoise(settings="high")

[feisty2]

using strong denoise will wipe all the details away which is terrible, a specifically designed for mosquito noise script should only work on mosquito noise

[feisty2]

I found Algolith MNR works pretty well for Mosquito Noise but it's an AE plug-in, any avisynth plugin can do a job like this?

[feisty2]

I think I found the answer, MCTD (settings="very low",edgeclean=true,ecrad=6)+SMDegrain () removes all the gibbs noise away but only gives me very little detail loss,it's even better than algolith

DeHaloAlpha and BlindDeHalo3 are my normal choices to remove ringing,... also see: http://avisynth.org/mediawiki/External_plugins#Dehaloing

but that's not ringing artifacts,it's mosquito noise which is caused by mpeg2 compression,not over sharpening

hups, sorry :)

you can try nonlinear smoothing loss-free in virtualdub, works pretty well on mosquito noise.

By itself I doubt that it will be as good as that combination, but have you tried MosquitoNR?
It's a plugin ported from AVIUtil. The documentation is in Japanese so we're stuck using the often wrong online translators.

Here's the author's Twitter post that includes download link. [click (https://twitter.com/b_inary/status/167881882862751745)]

Anyways, hope it helps. :)

anyone got an english translation of the MosquitoNR.txt? (btw. iirc UnDot was also intended for deringing)
also I can't get to work MosquitoNR with setMtMode :(

Not quite what you asked for.
But found it in the deep depth of my XviD4PSP's plugin folders.

As is.
Translation (seems terrible) is not mine. So do not shoot me. =))

Thanks, main downside with it just is, that it crashes for me with Avisynth MT as soon as I use SetMTMode anywhere in the script. :(
-> hoped that mode 5 would work,... :/

@ Selur

I can get MosquitoNR to work with MTmode 2.
With mode 1 I get thread deadlock and with anything >= 3 I get access violations. I'm using SEt's 2012.05.16 build. (http://forum.doom9.org/showthread.php?t=148782)
MosquitoNR is internally multi-threaded so believe it or not I get better performace without any MTMode. 76.82fps vs 59.22fps on 720p source.

thought I tried that :/ will try mode 2 again -> works now for me too with mode 2 (-> will keep an eye an it)

Normally I also use QTGMC and some other filters which get really slow without MTMode ;)

You might try UnDot() and TTempSmooth()
