Avisynth scripting

[demonwarrior]

is it possible to load more than one plugin in the same script?and how do i get the coordinates for denoise,im talking about the denoise plugin from Vcmohan,i have to put in the lx,rx,variables etc.The movieclip is mpeg1 size,352x240

Yeah, you can use as many plugins as you want, as long as you place them in the C:\Program Files\Avisynth\plugins
folder.

I'd use a different denoiser than that one. mohan makes some great plugins, but that one isn't very popular. With such a small source file (352x240), you might want to upsize, denoise, then downsize back to the original specs. The denosing will look a bit more natural that way.

Spline36Resize(720,480) #Upsize
DegrainMedian() #or you favorite denoiser
BicubicResize(352,240) # Back to Original Dimensions

[demonwarrior]

got any other denoise plugins,and how is his Removegrain plugins?

[Soopafresh]

RemoveGrain is written by a German fellow named Kassandro who is quite a brilliant programmer.

The choice of denoiser depends on your source file.

Download Fizick's (another programmer from russia) denoisers:

VagueDenoiser and Degrainmedian are really good.

He also has 2 others which are the best ones out there, but you'll need a bit of know how to use them.

Code:
Spline36Resize(720,480) #Upsize
DegrainMedian() #or you favorite denoiser
BicubicResize(352,240) # Back to Original Dimensions

well with the degrainmedian should i use variables or leave it the way you wrote it an use it?

[Soopafresh]

Depends on the amount of dirt you want to clean. The default is pretty good, so leaving the () empty is OK.

But again, it all depends on your source file.

Post a screen capture of a frame of your unprocessed video if you want more assistance.

[demonwarrior]

will do so tommorow,anyway i did an experiment but i only used the degrainmedian but then i saw more grain in the source,what u think happened?

ok here is one screenshot form one movie

The best denoiser is MVTools http://avisynth.org.ru/mvtools/mvtools-v1.8.6.zip

Unzip and Put the DLL it into your avisynth plugins directory

Script:

source=last
backward_vec2 = source.MVAnalyse(isb = true,blksize=8, delta = 2, pel = 2, overlap=4, sharp=1, idx = 1)
backward_vec1 = source.MVAnalyse(isb = true,blksize=8, delta = 1, pel = 2, overlap=4, sharp=1, idx = 1)
forward_vec1 = source.MVAnalyse(isb = false,blksize=8, delta = 1, pel = 2, overlap=4, sharp=1, idx = 1)
forward_vec2 = source.MVAnalyse(isb = false,blksize=8, delta = 2, pel = 2, overlap=4, sharp=1, idx = 1)
source.MVDegrain2(backward_vec1,forward_vec1,backw ard_vec2,forward_vec2,thSAD=400,idx=1)
sharpen(0.3)


You control the amount of cleanup with the thSAD parameter. Use 800 if 400 isn't enough. Also, this filter is slowwwww. Quality takes time. It shouldn't be too slow on a VCD source, but it'll still take a while. Yes, there is something you can do to speed it up. Buy a faster computer.

Here's the unprocessed image on top, and the MVtools degrained one on the bottom

thanks for your help will def try it
