avisynth filters and scripts

[jeo]

hello all!

where in the forum can i find and post about avisynth scripts and filters?

thanks!

[anonymez]

here, or xvid, or divx encoding subforums, if that's what you're encoding to...

anonymez,
i encode only dvds (no xvid&divx). i have one idea(if you excuse me i will send a pm (late))

thank you.

testing some filters.

filters used: Asharp,FFT3Dfilter,ColorMatrix and Deen.
was needed VDubMod 1.5.10.2 b2540,DGindex 1.76,avisynth 256 and Paint.
dvd toy story region 4,frame 4929

screenshots are from VDubMod using DGindex 1.76 (project.d2v)
with avisynth scripts (without resizes) and respective filters.
loading each scripts,VDubMod show in informations:
FourCC code: (YV12) - ATI YVU12 4:2:0 Planar,
Decompressor: DivX 6.0 YV12 Codec

one screenshot came from dvd ripped(dvddecrypter)
in VDubMod without scripts/filters.
another screenshot using script.avs without filters(no resizes too).

for comparisons,opening each screenshot in a new page is better than scrolling.
screenshots:

1) vob source


2) script without filters


3) ColorMatrix()


4) Asharp(1.25,3.75)


5) FFT3DFilter(bt=-1, sharpen=0.7)


6) Deen()


7) Asharp(1.25,3.75).Deen()


8) FFT3DFilter(bt=-1, sharpen=0.7).Deen()



compare this results with the vob source(screenshot 1) with:

colormatrix purpose is to correct coefficients but change overall matizes,
give too much solarizations and was left out.(screenshot 3)

Deen give great compression without change matizes.(screenshot 6)

Asharp is very good for details and Asharp/Deen give good sharpness/compression(screenshot 7)

FFT3DFilter is better for details and FFT3DFilter/Deen give great sharpness/compression(screenshot 8)


more details:

FFT3DFilter is better but very(very)slow,Asharp is 2,5 times faster(with CCE) and give tiny differences.
compare screenshots # 1, 7 and 8 and see the sharpness (baby's eyes) and in the shadows on the wall.

*using sharpen filters before any resize(bicubic,lanczos,etc),run faster and give more sharpness.
using others types of filters after resize is fast,give more compression and better effect.
example:
LoadPlugin("C:\ARQUIV~1\dgindex\DGDecode.dll")
MPEG2Source("D:\Test\DGINDE~1.D2V")
Asharp(1.25,3.75)
#FFT3DFilter(bt=-1, sharpen=0.7)
BicubicResize(720,480,0.0,0.6)
Deen()

nice to see your results. I've been doing alot of testing with Virtualdub and avisynth on some older bad files to see what results I can get.
