Simple script for very noisy source?

Code:

AviSource("C:\My Documents\noisy.avi",false)

ConvertToYV12()

Blur(0.8)

LanczosResize(528, 480)

Msharpen().Asharp()

TemporalSoften(2,7,7,3,2)

Limiter()

I tried this script with a few sources that were very bad quality and it seemed to improve it. The blurring killed a lot of details but that's what I wanted :D

I think that a correctly configured deen will be better.
Or if you are in avs2.0x, GoldDust.

Code:

AviSource("C:\My Documents\noisy.avi",false)

Limiter()

converttoYUY2() # as your dvix avi could be YV12

GripCrop(528, 480, source_anamorphic=false, dest_anamorphic=false) 

GripSize(resizer="BicubicResize")

TemporalSoften(2,5,8,3,2).peachsmoother().Unfilter(60,0)

GripBorders()

Limiter()

Just try .... :wink:
(peachsmoother is needed as you see)

Dialhot.
I'd be interested to see your script for this "noisy" issue, with the correctly configured deen. Can u post a sample so we can compare
to incredibles post?

Id like to try both. In fact, all three, side by side.

@ Rendalunit
You can also finetune the tempsoften settings to values really needed!
If the picture isn't that noisy just lower the TmpSmoother settings to:
(1,3,5,3,2)

I figured out this combination of these two filters in the "How funny thread" if the script is used for KVCD targets ... not KDVD! Cause the filter would not handle the full size (704) width as it does when using smaller width sizes, thats why I figured out there in the thread the down-upscaling "OneHalfOne" method.
By this the filter performs better and doesn't have to be set that heavy = more details less "static" grain on surfaces in motion scenes. And the soften which occurs during the process will be compensated by using Lanczos to resize finally again to 704.
But I'm still testing ... especially prediction results.

@ Eightball

DialHot's script is totally differend. Its intended to use with Dvix avis which often come with artefacts and also the script avoids artefacts when reencoding to mpeg1.
This one I posted is to kill Noise by still preserving sharpness and details (as DialHots script also does) and not to handle macroblocks. So you have to use different scripts for different sources.

This is my noise reduction script:

Code:

AviSource("C:/movie.avi") 

BlindPP() 

GripCrop(544, 480, overscan=1, source_anamorphic=false) 

GripSize(resizer="LanczosResize") 

Undot() 

Deen("a2d",2,10,12)

TemporalSoften(2,2,7,15,2)

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

Blockbuster(method="noise",detail_min=1,detail_max=8,variance=0.3,seed=5823) 

GripBorders()

i just used dialhot's avi2kvcd script and switched some stuff around. :D

I never meant using hte script for Divx ! You can use Deen in other script you know ? I didn't put a copyright on it :-p

A script with just AviSource and Deen will kill a lot of noise. Let's see what Jorel told in an other thread :

Quote:

deen("a3d",3,4,1,4) # light cleaning
deen("a3d",3,6,1,6) # medium cleaning
deen("a3d",4,9,1,9) # heavy cleaning

Yes Dialveryhot, I know and i do it often! But it sounded like he refered to your known Script in the Dvix Section as we are here :-P :D no offense..

Could you give me that URL of the Thread where Jorel did his tests on Deen(xxxxxxxx) ... cause I did also a lot of tests on it and I'd like to see his conclusions. Thanx

There was no conclusion in fact :

Oh, .. I thought you meant another Threat

Threat ? You is threaten you ? I don't bite, I'm very gentle :-)

There is an other thread talking about deen (whith conclusions) there :

Haha. I'm sorry for my late reply.
I missed the thread somehow. Yes as everyone seems to have determined, I was not referring to Dialhots brilliant Avi-divx-xvid scripts. I assumed that he was "capable" 8) of producing others. I was asking for a script that he would use to acheive the same or better results for cleaning messy sources.
Sorry, I could maybe have been more clear.
I'll buy you both a beer. (Big talk from Canada) :roll: :D [/quote]

????
I meant that you refered to a different "Thread" in this forum where also could be conclusions refering to deen included. :) Cause I knew that one you posted.
Sorry for wrong typing, but I think you can assume my intention Dialhot.

And again .... misunderstanding between us ... you already should know me a little bit ... I never bite .... I think and act positve ... maybe sometimes writing english including mistakes, but NEVER in a offensive way... except someones attacks me, but thats normal ... happened to me only one time ago in the spanish forum.

WOW is saw now in a dictionary what came out by writing wrong "thread" as "threat" 8O

RELAX!!!! :D

How about posting a Pic in here so that we can see what lines are really needed :wink:

You have to know that the scripts recommended in here are scripts for general purpose.
BUT as every source (especially AVIs) is different you have to use special combinations to attack your source individual and specific.

If you don't know how to post a pic, .. just get a free account at LYCOS incl. FTP upload so you can use the http://www.digitalfaq.com/archives/error.gif

Do you mean me, incredible?

I had a little tv commercial from Europe... funny but noisy. I tried your script, (just now) It worked F_A_N_T_S_T_I_C.

thanks,

About your last post, I didnt have anything in mind just now, but seeing how this worked, maybe we dont need anything else.

Ren, I tried yours too, Its way clearer.
