A mix of Udeband / GradFunk with new features...

I will add screenshots later...

jase99 · 23rd January 2009, 23:02

Wow, that was timely. Just what I was looking for. Thank you.

Adub · 23rd January 2009, 23:42

I long for the days when we will no longer need dithering and have high enough color bit depth to remove banding all together.

Oh, and LaTo, what's this? You posting a script with no "show" parameter!

Nah, it aint necessary but I got used to it. It's simple enough to implement my own source view.

Yes, this is clearly one of the biggest problems with DVD/Bluray (and others YV12 source)

Omission is repaired

LaTo · 25th January 2009, 20:35

Please re-download the v1.1 because I made a mistake in the show function

Haha!! Okay, now it's perfect! I have some anime that I can/need to test this on. If only I can find the time.

McCauley · 26th January 2009, 12:20

Hi LaTo,

great script, thanks!
Would it be feasible to implement the possibility to call an external Grain Generator (=Grainfactory3) instead of AddGrain?

Regards
McCauley

Sagekilla · 26th January 2009, 17:25

Ctrl+F -> AddGrain -> Replace with your choice

Why not... I will add a switch between Addgrain & GrainFactory3 later.

thetoof · 26th January 2009, 21:37

You could do it as string "mygraingen" and use eval in the script. This way, you wouldn't need to add all the possible parameters in gradfun2dbmod. (+ more flexibility if the user wants to use a combination of filters, etc etc) mygraingen="grainfactory3(blabla).something else()"

That's exactly what i had in mind, but i didn't really understand how to implement it with eval().

Sagekilla · 26th January 2009, 22:47

One way you can do this is to make a helper function.

Code:

function EvalFunction(clip src, string "filter")
{
src
processed = Eval(filter)
return processed
}

It makes script writing easier too:

Code:

# Without the helper function you have to do this:
Avisource("..")
src = last
proc = src.SomeFiltering()

src
dither = Eval("Blur(1)")

# With the helper function you can do this:
Avisource("...")
src = last
proc = src.SomeFiltering()

dither = src.EvalFunction("Blur(1)")

Wow took me a minute to see the difference without cheating by looking at the bottom, looks fantastic man.

So this filter mainly removes grainy sort of damage?

What program did you use to produce that shot for comparing, could save myself a lot of time if you're willing to care and share

Nightshiver · 26th January 2009, 23:21

This filter is for debanding.....

In my defense its still tuesday morning here -_-

The banding is caused by grain though is it not? i'll shut up now...

Nightshiver · 27th January 2009, 00:46

No, not always. Grain is sometimes put in movies to cover up banding. It is also caused by bad color gradients/color. In his example picture, there was practically no grain.

Sapo84 · 27th January 2009, 03:00

I think str parameter should be float (it is float in addgrain).
Otherwise it's really a good script, I tried it on some anime clips and it works very well, a lot better than a simple GradFun2DB.
The only problem is that anime shouldn't really have any grain so the default parameters need a little bit of tweaking

(supersampling may help too).

LaTo · 28th January 2009, 17:51

v1.2:
changed int->float for str parameter
added custom parameter
