Avisynth: Blocks!?
 

What settings would be the best to get rid of blocks in a flashing fast dancing scene, I´m just encodind Wasabi and I´m having trouble with this.
Here´s the script I´m using,

LoadPlugin("E:\KVCD Converting\Filters\Mpeg2dec.dll")
LoadPlugin("E:\KVCD Converting\Filters\GripFit_Preview.dll")
LoadPlugin("E:\KVCD Converting\Filters\LegalClip.dll")
LoadPlugin("E:\KVCD Converting\Filters\UnFilter.dll")
LoadPlugin("E:\KVCD Converting\Filters\STMedianFilter.dll")
LoadPlugin("E:\KVCD Converting\Filters\textsub.vdf")

AviSource("E:\-=[ CACHE ]=-\Wasabi.avi")
ConvertToYUY2()

LegalClip()
GripCrop(544, 576, overscan=2)
TextSub("E:\KVCD Converting\Wasabi - Fin - 25fps - 2001.sub")
GripSize(resizer="BicubicResize")
STMedianFilter(10, 50, 0, 0, 10, 50)
unfilter(50,50)
temporalsmoother(1,2)
mergechroma(blur(1.58))
mergeluma(blur(0.3))
GripBorders()
LegalClip()

hi CheronAph :)

this is the script that i'm using too!

answer me please friend:

is not low CQ that are causing blocks?
(i really don't know,than i'm asking)

blockbuster noise don't help you?

and,why do you use
ConvertToYUY2() ?
what are the advantages?

thanks in advance!
:wink:

CQ is 73, I don´t know what the blocbuster settings should be and about the ConvertToYUY2(), I have no idea what it is, I´m just copying scripts here!

first off all I assume that the blocks dont exist in the source avi,

I would try upping the max bitrate to allow a little extra for the fast action scenes.
I may stand corrected here but I seem to remember a behaviour with tmpg that increaseing the gap between min and max created a smaller file size, maybe Kwag could confirm this.
Also you could try using the 1/2 D1 template and change the gop to 24 and use mpeg1 if you are happy to use 352 x 576.

Jorel the ConvertToYUY2() is used when the source is RGB some of the avisynth filters dont like this, common with divx sources.

"I have no idea what it is, I´m just copying scripts here"

:lol: :lol: :lol: you are kidding of course.

try this in a little sample and see if help:

LoadPlugin("C:\....\BlockBuster.dll")
BlockBuster(method="noise", detail_min=1, detail_max=100, variance=1, seed=0 )

. :)

Thanks guys! I´ll try your tips, let´s see what happens!

forgive friend,i forgot:

use blockbuster after resize in the script.

:wink:

How high can I raise the max bitrate?

The X3 has a max bitrate of 2500,

I think some players dont like high mpeg1 bitrates so test yours.

Also you could try mpeg2...... can't hurt then you can use 5000

I am using mpeg-2, I tried 5000 but I didn´t get any sound! I´ll keep on testing!

Yes I think this may be a limitation of svcd, certainly Dvd does not have a problem with such high bitrates.

Svcd might be limited to 2500

This happens when DivX3 or 4(?) is used to decode the content. They seem to decode it to RGB whereas DivX5 keeps the colorspace at YV12.
