ColorYUV2, ColorYUV & Levels Graffers - 30 May 2012

[Overdrive80]

Thanks for you filters, coloryuv2 graffers is great but you can consider to implement the posibility of loading videos, too??

[StainlessS]

Thank you for the nice words, If I knew how to do that, I would, maybe one day I'll figure it out.

Hello StainlessS,

Because i am working a RGB picture, when i make manual movies colors corrections, i have tried to write a script for add percentage of red, green and blue layers upon the frames.
Colours says me it easier to use ShowRed, ShowGreen, ShowBlue and Merge the filtered result. (http://forum.doom9.org/showthread.php?p=1680461#post1680461)
Thus i have write this short script, which use AvsPmod users sliders function.

Avisource .......

LoadPlugin("C:\......\ColorYUV2_25_dll_20120529\ColorYUV2.dll")

[<separator="Red users sliders">]
off_y_red = [<"off_y_red", -256, 256, 0>]
rpow_y_red = [<"rpow_y_red", -256, 256, 0>]
spow_y_red = [<"spow_y_red", -256, 256, 0>]
pord_y_red = [<"pord_y_red", 0, 1, 0>]

[<separator="Green users sliders">]
off_y_green = [<"off_y_green", -256, 256, 0>]
rpow_y_green = [<"rpow_y_green", -256, 256, 0>]
spow_y_green = [<"spow_y_green", -256, 256, 0>]
pord_y_green = [<"pord_y_green", 0, 1, 0>]

[<separator="Blue users sliders">]
off_y_blue = [<"off_y_blue", -256, 256, 0>]
rpow_y_blue = [<"rpow_y_blue", -256, 256, 0>]
spow_y_blue = [<"spow_y_blue", -256, 256, 0>]
pord_y_blue = [<"pord_y_blue", 0, 1, 0>]

blue_processed = blue.ColorYUV2(off_y=off_y_blue, rpow_y =rpow_y_blue, spow_y =spow_y_blue, pord_y = pord_y_blue)
MergeRGB(red_processed, green_processed, blue_processed)
ConvertToYV12(matrix="Rec601") # use the same matrix as earlier

For you, has this ColorYUV2 use a sense ?

Is it possible to say : off_y put the color layer or the invert color layer on the frame with the same strength on dark and light luma tones (dark below 128, light above 128),
rpow_y put the color layer or the invert color layer strong on dark luma tones and lighter on light luma tones,
spow_y > 0 put the color layer on dark luma tones and the invert color layer on light luma tones and other side for negative values ?

Thanks

Hi Bernardd,
I thought I might be able to make it a little easier for you, so I spent a couple of hours doing RGBAdapt plugin,
just had to rip it out of RT_Stats (used only for Luma) and glued it together with the frame renderer.
Not much tested, but the only likely source of problems would be the LUT creator, and that has been working
fine for some tiime, so I dont expect any problems. Find it here:

It should not prove too difficult to mod your macro (or whatever they call it in AVSPMod).

EDIT: RGBAdust is quite similar to ColorYUV2, but it also has SPMid args for r/g/b, which affects the flexing or turning point
of the S-Power curve.

Hello StainlessS.
Well done !
I am impressed. In your very quick answer, you write a new plugin, but also you anticipate my whole luma range control need with the SPMid args.
Get something that you wish but you have not still wanted, it is marvelous.
This plugin is very efficient. With the graffer, a dummy like me know and understand that he is doing.
A minor bug 0.01 and 0.99 are not allowed for SPMid args. The graffer windows is not autosized, i cannot read the bottom, but it is not necessary in my case.
Thanks.

A minor bug 0.01 and 0.99 are not allowed for SPMid args

In Graffer or plugin ? (both look OK to me).

I'll squash the dialog box a bit to fit your 768 height.

[Bernardd]

0.01 an 0.99 are not allowed in plugin. I get this error message : RGBAdapt: Invalid R_SPMid(0.01 -> 0.99) {0.010000}
I use AviSynth 2.60A5 (CVS 20130920, ICL10) version.

[StainlessS]

Thank you sir, 0.01 comes out as 0.0099999 etc as a float conversion to double, will fix.
I did originally do the graffer thing for 768 display, however I obviously had to move things around
and forgot to put them back, hence the gap between sliders and bottom buttons, and your problem.
Thanks for pointing out the errors of my ways, I'm such a slipshod individual, sorry.
Will fix.

[StainlessS]

Bernardd, fixed the float->double conversion prob, fixed Graffer and included in zip.

StainlessS,
All is OK. Thousand thanks.
