Can these right-edge halos be corrected?

[Underbayversi]

Hi, i am new to doom9,avisynth and video processing. started this as a hobby while editing some of my dvds. i am faced with same problem of halo. while searching for solutions saw your thread. i hope your method may remove halos without losing quality. posting here beliving i may get help from you. please post your script so that i may apply it.

thanking you in advance

I would also like to know which script you used (in the post below) Avisynth_challenged


I tried it with FixVHSOversharp, but I get the bad faults

FixVHSOversharpL(30,12,8)
FixVHSOversharp(30,14,10)

FixVhxOversharp in Virtualdub "there is no function named" why?

(actually the example I put is not oversharped... it's just to show the defects of FixVHSOversharp)

FixVHSOversharp is an Avisynth plugin. Do you have it in your Avisynth plugins folder?

Now I put it into the Plugin folder, but it still does

LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\FixVHSOversharp2_5.dll")

I tried this script to generate the mask

(I did not understand if it is the right script)

then must use mt_merge?

how does it work? .. I'm not able

I tried with...

source = AviSource("D:\clip1.avi")
source2 = AviSource("D:\ghost.avi")
mt_merge(source, source2)



that fool

the right usage is mt_merge (clip1,clip2,mask)

with mask gives me error: I don't know what "mask" means

I use masktools-v2.0a48

and then still do not understand how to invoke the clip1 and 2 in mt_merge

clip1 = AviSource("D:\ORIGINAL.avi")
clip2 = AviSource("D:\HALO MASK.avi")
mt_merge (clip1,clip2,mask)

can you tell me what is the correct script to merge ORIGINAL with HALO MASK, to obtain FIXED?

but it is fair use mt_merge in this case?.. or it takes another method for merge?

please

mask is a variable. You don't have a clip set equal to mask.

mt_merge

mt_merge : clip clip1, clip clip2, clip mask, bool "luma"(false)

It's the backbone of the framework. It merges two clips according to the mask. The bigger the mask value, the more the second clip will be taken into account ( the actual formula is y = ((256 - m) * x1 + m * x2 + 128) / 256 )
luma is a special mode, where only the luma plane of the mask is used to process all three channels.
u and v are defaulted to 2 (that way, the resulting clip contains the chroma of clip1, and looks right).

Your "halo mask.avi" probably should be mask, ie: mask = AviSource("D:\HALO MASK.avi"), but I'm not sure what should be your clip2.

thanks, but thus opens without displaying anything

clip1 = avisource("D:\ORIGINAL.avi").ConvertToYV12(Interlaced=False)
clip2 = avisource("D:\ORIGINAL.avi") ### boh
mask = AviSource("D:\HALO MASK.avi")
mt_merge (clip1, clip2, mask)

but in fact do not understand what should be the clip2

Can you post your full script? The example script from Avisynth_challenged that I think you're copying doesn't use mt_merge.

I do not have another script

I copied the script of Avisynth_challenged for the mask, and then I tried to use mt_merge

if do not use mt_merge, what should use?

Please Avisynth_challenged

[ChiDragon]

Have you sent him a PM? He hasn't posted since Feb but has been on the forum today.

[byme]

yes, I sent him a message a few days ago, but did not answer

[smel]

Is anybody managed to make a script that can reproduce @Avisynth_challenged result posted at #13?
