For DVD and Clean Material in Avisynth?

Hi @kwag and the others!

Code:

For DVD and clean material (AviSynth 2.0x): 

Code: 
LegalClip() 

unfilter(50,50) 
GripCrop( X, Y ) 
GripSize(resizer="BicubicResize") 
STMedianFilter(8, 32, 0, 0, 8, 32) 
# SpaceDust() # Optional - for some "not so clean" DVDs. 
temporalsmoother(1,2) 
mergechroma(blur(1.50)) 
mergeluma(blur(0.2)) 
# Convolution3d or DCTFilter for extreme worse cases. 
GripBorders() 
LegalClip()

I've a question to the Optimal Script. Should I use Convolution 3D oder DCT Filter. Or Both together. When yes which settings I have to choose for the DCT Filter.
And my 2. Question: When should I use the Dust Filter when can I see it and which dust function should I choose?

Thank you for listening.

hy Encoder Master

use DtFilter like trbarry recomendations:
DctFilter(1,1,1,1,1,1,.5,0)
or (only my opinion) use
Deen("a3d",3,4,1,4)
you will got good compression!

but DctFilter and Deen (or Convolution) together are "too much",
isn't for DVD and clean material.

using Dust Filter
SpaceDust()
is to got big compression in DVD and clean material too
but is a little slooow!

see details from DustFilter read-me:

FaeryDust uses temporal filtering only.
It should preserve the maximum detail.
(Not really true yet with strong settings but will be

Recommended limit settings 1-5

SpaceDust is just the spatial filter from PixieDust.
It is for those who want the April version speed from Dust now

It can improve the visual quality quite a bit.
However unlike PixieDust, It can only reduce noise - not remove it.
So the compression gains (and compressed quality)
will be less.

PixieDust is essentially FaeryDust + SpaceDust (with some twists).
It isprobably the best to use for medium noise
and those who shoot for 1-CD encodes.
Recommended limit settings 3-8.

GoldDust uses heavier filtering. Not really very developed yet.

By the way Encodermaster ...
This script is for DVD "CLEAN" Material, you should use a differend based script to perform on duty material. Its not the way just to add and add other filters.

So what are you processing??
A DVD orig stream source??
or a Dvix? (other Topic in the Forum)

Do you want to "really clean" your material or just make it more compressable when using CQ?

Inc.

And in case of "dust" filter ..... "good things come to those who WAIT" .. as said in GUINNESS speech
