GradFun2DBmod [v1.5 - Update 2009/12/30] - Page 2

LaTo · 28th January 2009, 18:19

PS: If you really want supersampling (I haven't seen any enhancement):

custom="spline36resize(resolution*2).addgrain(xx,0,0).spline36resize(resolution)"

Could you give the pros/cons of the different parameters in the guide... you only name them, which is not very useful for unexperienced users. (that aside, good job ^_^)

stpdrgstr · 3rd February 2009, 02:19

I've been testing this, and is quite good, the only parts of the image dithered are the ones that really need it.

Though, I don't really see any difference from temp=100 or using temp=50, the grain looks the same "jumpy" with any of these.

I didn't want to start a new thread, so i posted my ply for help here.

This is the first 10 seconds of freedom OVA ep#2. The source has virtually no grain, however the color gradient is HORRIBLE. I have been trying for days trying to get rid of the banding in some way or another, but the end-result does not look very good. Somebody please take a look at the purple area in the background and tell me if you have a good solution for the banding here.

Thank you

v1.3:
replaced chroma parameter by thrC & strC

Thank you

GradFun2DBmod(thr=1.2,thrC=1.8,str=0.0,strC=0.0)

edit: If the effect disappear when encoding, you should increase str & strC until the dither remains.

Can GradFun2DBmod be applied straight to interlace video?

Or should a SeparateFields or the Bob/filter/reinterlace method be used to apply GradFun2DBmod to interlaced video?

Could someone please post AddGrainC 1.4 somewhere? The link from the avisynth plugin page to foxyshadis site is dead and I can't find the v1.4 plugin anywhere. Only managed to find 1.3....

Socio · 20th April 2009, 13:47

LaTo I have a side question; what app are you using in that side by side comparison in the OP?

Thanks

No app, just: GradFun2DBmod(show=true)

I've uploaded to the forum the 1.4 plugin:

http://forum.doom9.org/showthread.php?t=51320

It may take time before it is approved.

Hopefully, Warpenterprises will replace the old with the new.

Where did I get this? I don't recall.

SPiKA · 23rd April 2009, 19:18

Thanks LaTo, this script is amazing!

Nephilis · 3rd May 2009, 16:50

Where should i use GradFun2DBmod () (to avoid color blocking in dark areas in a frame) in the filterchain? At the last of script or somewhere else? Before or after sharpen, denoise ?

Thanx in advance..

SPiKA · 3rd May 2009, 17:07

It's rather pointless to use it before denoising... xD

Sagekilla · 3rd May 2009, 21:34

Generally I would use debanding after denoising, but not before sharpening. If you do it before sharpening, the sharpener may accidentally sharpen your dither.

i.e:

Code:

Denoise()
Deband()

or

Denoise()
Sharpen()
Deband()

Nephilis · 4th May 2009, 12:41

I'll do it so

Quote:

Denoise()
Sharpen()
Deband()

Thanx a lot Sagekilla..

Zelos · 5th May 2009, 18:29

it's me or it's horribly slow ?

Sagekilla · 6th May 2009, 03:06

Well yes, It's slower than your standard Gradfun2db, but that's because it has multiple masktools operations and some temporal soften + add grain sprinkled in. Temporal soften is fairly slow, and the mt_lut's don't help any either
