Avisynth: Pretty Good Script?

Steel · #1 08-22-2003, 06:26 PM

heres my script for dvd rips and whatnot. anyone that has ideas for how to get it better, please let me know. but remember i prefer quality over size.

Code:

LoadPlugin("C:\Filters25\MPEG2Dec3.dll") 
LoadPlugin("C:\Filters25\GripFit_YV12.dll") 
LoadPlugin("C:\Filters25\asharp.dll") 
LoadPlugin("C:\Filters25\unfilter.dll") 
LoadPlugin("C:\Filters25\undot.dll") 
LoadPlugin("C:\Filters25\VagueDenoiser.dll")
LoadPlugin("C:\Filters25\Deen.dll")
LoadPlugin("C:\Filters25\STMedianFilter.dll")
LoadPlugin("C:\Filters25\temporalCleaner.dll")
LoadPlugin("C:\Filters25\DCTFilter.dll")
LoadPlugin("C:\Filters25\decomb.dll")

MaxTreshold = 1.50 
nf =  0 # Current frame. 

Mpeg2Source("C:\Documents and Settings\owner\Desktop\File.d2v") 

undot() 
Telecide(guide=1)
deen()
asharp(0, 7) 
STMedianFilter(8,32,0,0)
GripCrop(528, 480, source_anamorphic = true, Dest_Anamorphic = false) 
GripSize(resizer="BicubicResize") 
MergeChroma(blur(1.58)) 
MergeLuma(blur(0.3)) 

SwitchThreshold = (Width<=528) ? 4 : (Width<=528) ? 3 : 2 
ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf >= SwitchThreshold ? \ 
unfilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ) : \ 
TemporalSoften( fmin( round(2/nf), 6), round(1/nf) , round(3/nf) , 1, 1).VagueDenoiser(Threshold=1.5,method=1,nsteps=6,chroma=True,Filter=7)")



GripBorders()
DCTFilter(1, 1, 1, 1, 1, 1, 0.5, 0)


function fmin( int f1, int f2) { 
  return ( f1<f2 ) ? f1 : f2 
}

very best scripts used in kvcd forum:
http://www.kvcd.net/forum/viewtopic.php?t=3483

remember,if you don't have problems with final size,
use 704x480 and encode for 2 or 3 cds...the result will be fantastic
....but the size too big!

The script is basically what we suggested back in April: http://www.kvcd.net/forum/viewtopic.php?t=4817
It takes too long to encode, with barely any visual quality from the regular script. VagueDenoiser works better without all the overhead of the other filters, and that makes it faster too. This script will probably be useable in 2004 or 2005, with Pentiums running ~4Ghz, or if Vague is further optimized for today's CPUs

That's why Vague is not included in the optimal script

yeah i see what you mean kwag... takes bout an hour to predict, and 20 hours to encode my movie

so i ditched that (for now

) bit im still wondering what you guys have to say about deen, the high luma blur, and dctfilter... i read in another post that those thing can really help.

Code:

LoadPlugin("C:\Filters25\MPEG2Dec3.dll") 
LoadPlugin("C:\Filters25\GripFit_YV12.dll") 
LoadPlugin("C:\Filters25\asharp.dll") 
LoadPlugin("C:\Filters25\unfilter.dll") 
LoadPlugin("C:\Filters25\undot.dll") 
LoadPlugin("C:\Filters25\STMedianFilter.dll")
LoadPlugin("C:\Filters25\temporalCleaner.dll")
LoadPlugin("C:\Filters25\DCTFilter.dll")
LoadPlugin("C:\Filters25\deen.dll")

MaxTreshold = 1.50 
nf =  0 # Current frame. 

Mpeg2Source("C:\Documents and Settings\owner\Desktop\SomeMovie.d2v") 

Deen()
undot() 
asharp(0, 7) 
STMedianFilter(8,32,0,0)
GripCrop(528, 480, source_anamorphic = true, Dest_Anamorphic = false) 
GripSize(resizer="BicubicResize") 
MergeChroma(blur(1.58)) 
MergeLuma(blur(0.3)) 

SwitchThreshold = (Width<=528) ? 4 : (Width<=528) ? 3 : 2 
ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf >= SwitchThreshold ? \ 
unfilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ) : \ 
TemporalSoften( fmin( round(2/nf), 6), round(1/nf) , round(3/nf) , 1, 1)")


GripBorders()
DCTFilter(1, 1, 1, 1, 1, 1, 0.5, 0)


function fmin( int f1, int f2) { 
  return ( f1<f2 ) ? f1 : f2 
}

and i know i said i prefer quality, but i wouldnt want to go over 2 discs... just in case i were to share it with a friend over the net

The MA Script already have the high luma blur:

Code:

MaxTreshold = 1.50 
.
.
.
MergeChroma(blur(MaxTreshold))

If my memory is still good, the 1.58 values gave artifacts in some cases.

I'm just encoding Harry Potter and the chamber of secrets (2h30), at 704x576, and it fits in 2 CD, en dual, with CQ 71. Let's see the result in a few hours, but with MA script, it lasts 8 hours, and I'm sure the quality will be like a DVD!

Fabrice, this the Chroma blur, not luma. Luma is the line just after

@Steel : you blur a lot too much ! For sure it helps for shrinking the file size, but your movie will be unwatchable !

I know I should read more carefully!

For mi 0.3 is not a heavy blur!

I tried using this blur value in my last DVDRip, to get a higher CQ value, but I was visible on the TV (or I have to clean my glasses!

)

I finally let 0.1, and increase the overscan value...

i used .3 on a dvdrip, and it was very watchable... ill probly lower it down to .2 though

im just talking in theory... of course id never do it... so what do you guys think of deen? the end product seemed about the same with and without it, but then again i was doing a film thats over 2 hours, and i had to put it on 2 cd's

Deen is good used alone. But there, I didn't test, but I think is too much. I'm surprised that you can watch movie produced by your script. Into my eyes, that should seem like seen throught londonian fog

Steel · #12 08-23-2003, 05:57 PM

i actually didnt use deen in the one i just did, so that may be why...

fabrice · #13 08-24-2003, 01:05 AM

Hi,

I think Dialhot was speaking about blur(0.3). You actually don't see the fog, because you only watch this movie, but watch it after a DVD, and you'll see exactly what Dialhot say: Londonian fog!

And you don't have to put it on 2 CD: I just encode the 2h40 movie at 352x288, with a 73,77 CQ, min 300, and max 2000. Have to see if it's watchable! Just try it!

will do fabrice

thanks for the help guys
