Fixing Comets

[Andreselos]

Hello Guys how to remove this artifact?
I believe it's called comets right?
Thanks in advance!

Yes, it's called comets.

On raw, un-deinterlaced and unfiltered video, DePulse works nicely.

Your video seems to be deinterlaced and denoised however, which makes the comets fat and DePulse does not expect that. You need the raw interlaced video.

ok thanks, i will try!

Unfortunately, you video has been deinterlaced so DePulse will probably not work well.

this will remove some, without artifacts

SetMemoryMax(900)
SetMTMode(3,4)
LWLibavVideoSource("sample.mkv")
SetMTMode(3,4)

noisy = last
nonoise = SpotLess(last)
sharpen=0.0,interlaced=false,dehalo=0.0)
diff = 1 # Difference between denoised and noisy clips
m = mt_lutxy(noisy,nonoise,"y x - "+string(diff)+" - 255 *")
mt_merge(noisy,nonoise,m)

syntax error appears on line 8 column 12

noisy   = last
nonoise = SpotLess(last)
diff    = 1                        # Difference between denoised and noisy clips
m       = mt_lutxy(noisy,nonoise,"y x - "+string(diff)+" - 255 *")
mt_merge(noisy,nonoise,m)

Like this, sorry

mt_merge(noisy,nonoise,m)

Like this, sorry

I tried like this

SetMemoryMax(900)
SetMTMode(3,4)
LWLibavVideoSource("sample.mkv")
SetMTMode(3,4)

noisy = last
nonoise = SpotLess(last)
diff = 1                        # Difference between denoised and noisy clips
m = mt_lutxy(noisy,nonoise,"y x - "+string(diff)+" - 255 *")
mt_merge(noisy,nonoise,m)

and it's giving scripterror: There is no function named 'SetMTMode'

What version of Avisynth do you have installed? Try

SetFilterMTMode

SetFilterMTMode

It didn't work either, I have AviSynth+

Remove all the SetMemoryMax() and SetMTMode() and SetFilterMTMode() lines.

And always indicate the error message you got.

This is good advice for beginners. I played around with it last year, but never had much luck.
There's an mtmodes.avs that has the modes for all the popular filters, even still,
seems like a bit of a kludge.

Probably better to learn Vapoursynth
