MAM artefact and ghosting effect

[kyousuke]

marc! i've found a problem.
i don't know if it my fault but with this setting :
MAM(Cnr2().TemporalSoften2(1,10,1),SmoothHIQ(3,15,20,180,15))

on the screen shot, we can see the frame 617, with mam the denoising blur the picture a little and all is really ok :)
the frame 618 is a new frame and the frame is ok but... after... on the frame 619-620-621-622-624-625 (it's not a joke!!!) some artefacts of the previous scene reappear! I don't know why! :(
and the ghosting effect removed by decomb reappear too as you can see (on the frame 619). write MAM() before or after Decomb() change nothing ;___;

help me ! ^^;

your new filters can help ?

thks you :devil:

i'm going to sleep right now, then i would fix some MMX in CopySame, then update the CopySame doc, then i will release it...
... after that i think a mod would have accepted your screenshot and i would take a look on you pb (yep, MAM is still "crappy&buggy"[tm])

Ahhh, anime ;)

i analysed it a bit...
you're using Cnr2().TemporalSoften2(1,10,1) in temporal softing.
very good idea : it's exactly the filters i recommend.
BUT using the temporalSoften2 settings may be the pb :
you're here using 1 in chroma. i think the iteration of the 2 temporal filters on chroma create a raduis 2 ghosting effect.
to check that, frameserve the following .avs script to VDub :
#all the stuff you need (loadplugs,*source,ect...)
Cnr2().TemporalSoften(1,10,1) # use avs 2.0.4 with ts2 as ts

you should see ugly artifacts in frames 618,619,...625,..ect..

MAM remove the raduis-1 ghosting effect, so frame 618 look really good (i'm pleased to see how good it works :cool: )

You should try :
MAM(Cnr2().TemporalSoften(1,10,0),SmoothHIQ(...))

the iteration on chroma & luma would be disabled, so the ghosting would never be over reduis 1.

Check if TemporalSoften(1,x,0) is 2x faster than TemporalSoften(1,x,x)
if not, maybe dividee could consider adding an ultimate optimisation :)

MAM(Cnr2().TemporalSoften(1,10,0),SmoothHIQ(...)) > it is the same to write (1,10,1) or (1,10,0), it changes nothing :eek:

MAM(Cnr2().SmoothHIQ(3,15,20,180,15)) works very well as i thought... but no more TSoften there...

MAM(Cnr2().TemporalSoften2(1,10,1))
or
MAM(Cnr2().TemporalSoften2(1,10,0))

this time, it's the frame 618 which is very bad with some big artafacts and ghosting effects... the others frames after are ok :eek:

... so the problem was TemporalSoften... what to do ? use an other filter ?

[Marc FD]

have you avisynth 2.0.4 ?? if not dl it.

[kyousuke]

i've v.2, 0, 4, 0 ....

[Marc FD]

really strange. i haven't tested MAM a lot.
hope you'll be able to find good settings.

PS : are you using blend / no-ghosting or no-blurring mode ??

[kyousuke]

and as i said, as become again ok when i remove TemporalSoften is the script ...... :angry:

this story is annoying :mad:
