You could play with C3D or other temporal filters, and use very conservative low values :idea:

I don't mind waiting forever either if it means better quality! :D
Would Convolution3D(preset="movieHQ") be conservative enough? And if so, where would you suggest it should go? After SpaceDust()?

I also noticed you're not using DCTFilter anymore...is it still needed :?:

I really don't notice that much file size reduction after using the mergechroma/luma functions. You can use C3D after the mergeluma. So the order I would use, would be this:

Code:

LegalClip()
GripCrop( X, Y )
GripSize(resizer="BicubicResize")
SpaceDust()
sharpen(0.7)
mergechroma(blur( 1.58 ))
mergeluma(blur(0.7))
Convolution3D(preset="movieHQ")
GripBorders()
LegalClip()

Kwag:

Just checked out your sticky for the current optimal script (so you can ignore my PM asking for what script you use now! :) ) I was just wondering if you are still using overscan=2 in the GripCrop command. Thanks!

I'm currently trying muaddib's suggestion on using "overlap" instead of "overscan" :wink:

8O Oh man! KVCD.net is really an amazing and dynamic place!
I melted my modem and lost my connection for 3 days...
When I came back I found lots of different ideas and filters and optimizations! Just GREAT :!: :mrgreen:

Btw kwag, I use "overlap" for anamorphic/widescreen and "resize" for fullscreen. :wink:

Need opinions/revisions...
 
Hey, all.

This is my current "Ultra Detail" script. Let me know what you think.

Have you guys tried exchanging Sharpen to Unfilter? Unfilter is a helluva lot faster and should produce similar sharpening.

again i'm with you Boulder friend! :wink:

i ever use unfilter....ever!
you know, using gently turn the image very clean!
for me is the very best of all filter that i know!
muaddib promisse to use unfilter in the next MovieStacker version!
:D :D

:wink: :wink:

any value suggestions for unfilter? the readme says, something between -100 an +100

nerver used it before, wanna give it a try


edit:

i tried several settings now. if i increase the unfitler values to maximum i get a slightly shaper picture than with sharpen, but i couldnīt notice any increase in encoding speed

jorel 04-04-2003 05:47 AM

hi Kane :)
yes,of course...

use gently,high values gives strong sharpness.

try in a sample,depend of the size(480x480 or 352x240,etc) that you use:

unfilter(5,5) or unfilter(10,10) or unfilter(20,20).

in 480x480 mpeg2 ,for me is better:

unfilter(10,10) !

:wink:

Kane 04-04-2003 06:22 AM

have you ever tried combining those two filters, i just made a sample using this script

Code:

LegalClip()
GripCrop(528, 576, overscan=1, source_anamorphic=false)
GripSize(resizer="BicubicResize")
Spacedust()
UnFilter(10,10)
sharpen(0.7)
mergechroma(blur( 1.58 ))
mergeluma(blur(0.7))
GripBorders()
LegalClip()
Sampler(length=24)

it takes 40 sec longer to encode, but gives a sharper and more clear picture, better than using only one filter
the sample is about 1.2MB bigger with both filters 8O , hmm, letīs see what the fully encoded movie will look like

I haven't. Will give it a try today :wink:

Hmm, I'll have to take back my words regarding the speed of Unfilter. It seems that Sharpen has been optimized since I last tried it out and it's nearly as fast as Unfilter. I don't know what their difference is in terms of quality but nevertheless could be worth a try.

Not at all Boulder :!: In a 30 second clip, the speed to encode was 2:09 with sharpen, and 1:57 with unsharpen :D Quality and file size are almost identical using a test clip with Sharpen(0.3) and unfilter( 30, 30 ).
This is under AviSynth 2.08.

You can get it at the software section at doom9.org.

This is a great thread...
can anyone answer the following, (I`m sure you can.. :D)

What are the differences that you find using:
GripSize(resizer="BicubicResize")
instead of:
GripSize(resizer="lanczosresize")

And...
is the argument:

sharpen(x.x)

an imported .dll...or is this a "built-in" function of Avisynth. (NoOb alert!)

Thanks a lot guys!.. :D

sharpen is within avisynth
iīve never tried lanczos resize, i always use bicubic

Thanks for the answer for sharpen Kane.. :D

I`ve been using lanczos on all my scrips recently, and have
seen a lot of people using bicubic...just wondering why?

Lanczos produces sharper edges, which then create more visible mpeg artifacts by the encoder.

hmm... so many script so little time...

can anyone recomend a good script to me to use when turn my WAV

using Headac3he?? :idea:

thanx
