New optimal script (V4) is there

Hi all,

After many tests and some good feedbck about it, this is the new optimal script for making avi->kvcd encoding :

Code:

AviSource("PATH\NAME.avi",false)

BlindPP(cpu=4)

Blockbuster(method="noise",detail_min=1,detail_max=3,variance=0.1,seed=1)

Convolution3D(1, 6, 12, 6, 8, 2.8, 0)

GripCrop(WIDTH, HEIGHT, source_anamorphic=false)

GripSize(resizer="LanczosResize")

Undot()

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

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

#Blockbuster(method="noise",detail_min=1,detail_max=10,variance=0.3,seed=5623)

GripBorders()

The second Blockbuster line should be used in rare occasions when there is too much DCT blocks done by the MPEG encoder. I used it only twice.

So the only difference is that ATC is subtituted with Convolution3d, right?

Right.

Why you choose 2 times Blockbuster and not deen? With deen I have very good results at a very low bitrate and old video better tha blockbuster.

What's your point Encoder Master?
You are comparing a Denoiser with a filter to stray noise in low detail areas... How can you exchange one for the other?

Oh sorry I had a wrong knowledge about Blockbuster and I 've thought It's like deen. :oops: :oops: :oops:

And you had bad knowledge also of the script history : V1 used Deen !

We dropped it because it does not do a good job at all.

Was your message just for giving us a chance to see again your boring signature ? Wa are not there to make silly adds for websites ! :-(

Thank you very much for the update Dialhot ive been using the newer V2 script and had some excellent results look forward to seeing the improvements with this one. :)

Encoder Master ...
My recommendation:

1. Read the threads!... especially in here, the Avisynth- and Optimal Script section! Read the threads of the released optimal scripts 1,2,3 and you will see why there is something used in a line of a script.

2. Read the readme's of each filter you downloaded! As I recommended it to you already.

3. Get rid of your SIG. It has nothing to do with mpeg business or with contents about yourself

First attempt with the new script and this is the error i get

Code:

Convolution only supports YUY2 color format only

First time i have ever got this message

If all i have to add is a convert toYUY2 line where do ihave to put it

thanx

you don't have to use ConverttoYUY2. There is a convolution3d plugin made for YV12 colorspace, so use that instead. :)

THnax muhali3,where do i get it ,i just downloaded the convolution 3d today from warpenterprises.did i get the wrong one

Maybe you already know this but the temporal influence is disabled in convolution3dyv12.

It should be a funny game. :cry:
And sorry with the critik wasn't correct. :wink:

Yes, but we need the temporal influence there.
Try without it to see the difference.

Which means that you should use the YUY2 version in your script. The YV12 version doesn't do any temporal filtering as Dano stated.

sorry guys, my mistake. :roll: :lol:

I didn't notice that. So I change my answer : I din't know what they called "temporal influence" in the doc, but it seems that the temporal _filtering_ is on.

Influence is normally the forth paremeter (set to 2.8 in the script). I guess is something used for balancing temporal filtering according to some paramaters, but really don't see anything else.

Now, if I'm wrong, then that means that the script do not need a spatio-temporal filter there, but I'm pretty sure it does (I tried other filters and spatial only ones gave poor results).

Ok guys,is the solution to my problem in those answers,im having trouble figuring it out

Code:

Convolution only supports YUY2 color format only

Thanx again

Dialhot please don't yell at me if it is :D because :imstupid:

well bigggt, im using the YV12 version and i'm still getting good results. I am encoding the matrix (1st one) and the quality is very good at 352x480, the only problem is the mosquito noise. It's all over the place :x

could someone suggest what i should do to reduce mosquito noise at low resolutions (<352x480)?

Thanks :)
