Avisynth Script Help!

[}{KeYmAkEr*}{]

Hello

I'm encoding a dvd source but it has a lot of noise in it and it slightly flicker...thats why I'm using the denoising filters.

If I have the order of any of the pluins let me know or anything else to tweak it...thanks

Usually I denoise before resizing !!!

Maybe you wanna give my favorite denoiser a try...

Thanks 4 that....

What are the advantages or disadvantages of putting denoising before resizing?
In GordianKnot it says it will take longer if you do this?

So will it be crap if you resize than denoise...

well the denoiser has got more information to work with so it'll yield better results - or in other words more detail will be preserved!

well the denoiser has more information to process so it takes more (cpu) time

no it will work aswell - a little faster, but also a little less detail, most likely no noticeable difference though (imho)

Thanks for the info....

As for the vaguedenoiser filter do I just leave all the default options then encode...thanks

Dont know ya source !!!

But I like to set the chroma threshold 25-50 % higher than the luma threshold...

My source is just a Normal NTSC DVD progressive.

Could you give an example of the script: (e.g VagueDenoiser(threshold=0.8,method=1,nsteps=6,chromaT=0.8)

I want to use light or medium denoising.

[Soulhunter]

Try this here...

VagueDenoiser(Threshold = 0.75, Method = 1, NSteps = 6, ChromaT = 1.00)

Wicked thanks 4 that !

If I'm already using undot in my avisynth script will it make any difference if I have it enabled on the xvid decoder options (deblocking)?

Two different pair of shoes...

If you need undot to clean the (input) source, use it !!!

If you see blocks in you encode while playback, use deblocking...

So I don't need to add this for VagueDenoiser (debug, interlaced,wavelet,Wiener,wratio,percent)

Whats the lowest threshold that I should put in? Threshold=0.50 or lower seems to have a less blurry effect and more detail but a tad bit more grain.

I noticed this VagueDenoiser also helps with flickering in this film so its all good!Thanks

------
Also due to the blurry effect after using this filter is it a good idea to use a sharpening filter e.g MSharpen before Lanczos resize or after?

I noticed that using a MSarpen after Lanczos resize that the image becomes edgy...step effect

[Soulhunter]

Maybe, Crop -> VagueDenoiser -> Lanczosresize -> LimitedSharpen...


Denoising rules:

- Higher threshold = more denoising = more burry but less noise

- Lower threshold = less denoising = less burry but more noise

How do I get LimitedSharpen to work on my avisynth script?

I've got MaskTools-v1.5.1 ....loaded the MaskTools.dll iinto avisynth script.

Put this after Lanczos Resize:
LimitedSharpen(ss_x=2.0,ss_y=2.0,Smode=2,strength=100,Lmode=1,overshoot=1,wide=false,soft=false,radius=1,edgemode=0)

But it goes there's no function named LimitedSharpen?

Is there a LimitedSharpen.dll somewhere that i forgot to download?

Ohh....and the link to the LimitedSharpen Samples seems to be down.

[Soulhunter]

The link is right, but mf's forum is down atm...

You have to load the LimitedSharpen.avs as well !!!

Save LimitedSharpen as avs and place it in ya plugins folder, then...

LoadPlugin("C:\Blah\AviSynth 2.5\plugins\MaskTools.dll")

LoadPlugin("C:\Blah\AviSynth 2.5\plugins\WarpSharp.dll")

Import("C:\Blah\AviSynth 2.5\plugins\LimitedSharpen.avs")

Mpeg2Source("C:\Movie.d2v")

Crop(0,56,720,364)

VagueDenoiser(Threshold = 0.75, Method = 1, NSteps = 6, ChromaT = 1.00)

LanczosResize(720,304)

LimitedSharpen(ss_x=2.0,ss_y=2.0,Smode=2,strength=100,Lmode=1,overshoot=1,wide=false,soft=false,radius=1,edgemode=0)

Thanks for the help but it looks a little dull and dark...

is there a good way to brighten the hue,saturation,brightness etc?

I'll probably use VagueDenoiser(Threshold = 0.25) Don't like it too blurred

After Lanczos resize MSharpen (threshold = 25) as well.

brightness, contrast, etc:
