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 ^_^)

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

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?

Thanks

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.

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..

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

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()

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
