YUV color picker?

Reel.Deel · 24th February 2015, 15:30

Hi,

I was wondering if someone knows of a YUV color picker that can correctly tell you the hex value for a color in the 601/709 (TV and PC range)? Something like this but in YUV: http://www.w3schools.com/tags/ref_colorpicker.asp

I know AvsPmod displays YUV values but it does not have a color picker. There's the also the color presets page in the wiki but colors are for RGB.

Edit: Blankclip has the color_yuv parameter but what is it based on? 601 or 709?

Googled "color picker yuv", seems no shortage of choice

Yeah, I saw that page while searching yesterday but what gets me is the slight color difference when using a 709 matrix. So I was looking for a something similar to that can tell me the correct value based on the matrix that I want to use.

This any good to you ?

EDIT: Take 3

Code:

Function RGB_2_YUV(Int RGB_Color,String Matrix) {
    RGB_Color=RT_BitAnd(RGB_Color,$FFFFFF)
    BlankClip(Width=16,Height=16,Length=1,Color=RGB_Color)
    c=ConvertToYV12(matrix=matrix)
    current_frame=0
    Y=c.YPlaneMin() U=c.UPlaneMin() V=c.VPlaneMin()
    Col = (((Y*256)+U)*256)+V
    return Col
}

RGB=$FFFFFF
Matrix= "Rec601"             # "Rec601", "Rec709", "PC601", "PC709"


YUV=RGB_2_YUV(RGB,Matrix)
SRGB=RT_Hex(RGB,6)
SYUV=RT_Hex(YUV,6)

Messageclip("RGB = $"+SRGB+" : YUV=$"+SYUV + " (Matrix="+Matrix+")")

Or this

Code:

Matrix    = "Rec601"             # "Rec601", "Rec709", "PC601", "PC709"
ColorsRGB = "colors_rgb.avsi"
ColorsYUV = "colors_yuv_"+Matrix+".avsi"

Assert(Exist(ColorsRGB),ColorsRGB+" Does not exist")

Exist(ColorsYUV) ? RT_FileDelete(ColorsYUV) : NOP

PAD = 40
INSERT=RT_String("(yuv values [Matrix='%s'])",Matrix)

GSCript("""
    TEXT=RT_ReadTxtFromFile(ColorsRGB)
    LINES=RT_TxtQueryLines(TEXT)
    
    for(i=0,LINES-1) {
        S=RT_TxtGetLine(TEXT,i)
        S=(S!="")?RT_StrReplaceDeep(RT_StrReplace(S,Chr(9)," "),"  "," "):S
        S=(S!="")?RT_StrReplace(S,"(rgb values)",INSERT):S
        While(RT_Ord(S)==32) {S=MidStr(S,2)}
        if(RT_Ord(S)==RT_Ord("#") || RT_Ord(S)==0) {
            S=(RT_Ord(S)==0)?Chr(10):S
            RT_WriteFile(ColorsYUV,"%s",S,Append=True)
        } Else {
            Hx = RT_FindStr(S,"= $")
            Assert(Hx!=0,"Cannot find Dollar")
            SOUT=RT_StrReplace(LeftStr(S,Hx-1),"color_",Matrix+"_",sig=false)
            SOUT=RT_StrPad(SOUT,40)
            RGB=RT_HexValue(S,pos=Hx+3)
            YUV=RGB_2_YUV(RGB,Matrix)
            RT_Writefile(ColorsYUV,"%s= $%0.6X    # RGB = $%0.6X",SOUT,YUV,RGB,Append=True)
        }
    }    
""")
return MessageClip("Done")


Function RGB_2_YUV(Int RGB_Color,String Matrix) {
    RGB_Color=RT_BitAnd(RGB_Color,$FFFFFF)

And here Mp4 version (Rec601, 2MB): LINK REMOVED, See Post #21
Jumps upwards one color at each frame (each second).

EDIT: VLC dont like the MP4, maybe because only 1.0 FPS (and/or 117kb/s).

I would say that it is not based on anything, its just YUV as RGB is just RGB.
Only during conversion does rec601 or rec709 have any meaning.
EDIT: Had to check, "Color_yuv only valid for YUV color spaces", error if using color_yuv with rgb result in BlankClip.

EDIT: The diligent amongst you might notice two copies of "color_palegoldenrod" in the mp4,
this is a duplicate in colors_rgb.avsi as installed by v2.6RC1, you might like to delete duplicate from your copy,
reported in RC1 devs thread.

EDIT: Changed posts #5 and #7, changed names from eg "global color_skyblue" to global Rec601_skyblue" and "global Rec709_skyblue"
so can use the different colors avsi scripts together without conflict.

EDIT: You can call avsi creation script using "PC601" and "PC709" as Matrix string instead of documented "PC.601" and "PC.709",
the dot would break the global names (dot not valid in a variable name) in result avsi scripts. (valid for both post #4 and #5)

Reel.Deel · 22nd September 2015, 14:11

I'm wondering how can I use RGB_2_YUV(post #4) to feed the color_yuv argument of Blankclip? Using Hex(RGB_2_YUV($191970, "Rec601")) returns "2ea67a" but it's missing $ and it's also a string.

vivan · 22nd September 2015, 14:45

But you just don't need Hex.

Code:

BlankClip(pixel_type="YV12", color_yuv=RGB_2_YUV($191970, "Rec601"))

or why even use all of this when you can simply

Code:

BlankClip(pixel_type="YV12", color=$191970)

Oops, I forgot about that. Thanks for the reminder. The reason I cannot use color=$191970 directly is because I'll get color differences depending on the matrix used. That's why I'm using RGB_2_YUV.

Well, if you need other than Rec601, then you can use

Code:

BlankClip(color=$191970).ConvertToYV12(matrix)

(which is exactly what StainlessS does to calculate value in his function)

jmac698 · 22nd September 2015, 20:10

Yes the hex value you want to use depends on the matrix, a rule of thumb is to use rec709. The differences aren't large (compared to rec601) but noticeable in green objects.

That works but it's indeed much slower:

~355fps

Code:

BlankClip(length=100000, width=1080, height=720, pixel_type="RGB24", color=$191970).ConvertToYV12(matrix="rec709")

~6878620fps

Code:

BlankClip(length=100000, width=1080, height=720, pixel_type="YV12", color_yuv=RGB_2_YUV($191970, "rec709"))

Gavino · 23rd September 2015, 08:46

This should be much faster than 355fps:

Code:

BlankClip(length=1, width=1080, height=720, pixel_type="RGB24", color=$191970).ConvertToYV12(matrix="rec709")
Loop(100000)

Reel.Deel · 23rd September 2015, 14:30

Yup, runs about 2847930fps. I somehow manage to sometimes overlook the obvious things in AviSynth :/.

If you'd like to calculate the RGB <-> YUV conversions directly, these may be of some use.

@ StainlessS

How can I add PC.709/601 to the script in post #8. I tried modifying the script but when I tried loading I get this error:

Quote:

RT_DBaseAppend: Error, DB(0) : Incorrect number of field variables(6) Expecting 4

Took a look at the RT_Stats docs but I'm not sure how to fix it.

StainlessS · 5th October 2015, 23:03

Try this (not much testing, but think should be ok).
Have commented where made changes. You just needed to add two more 'i' fields to RT_DBaseAlloc() so s field moved to field 5.

Thanks StainlessS! I was close but missed adding the 'i' fileds. One more thing I wanted to ask, is there an easy way to keep the color name row be stationary? Eventually I want to make a gif out of this and add to the the wiki.

#Edit: some colors look similar due to the gif color limitations but overall looks nice

Hi, I was wondering if someone knows of a YUV color picker that can correctly tell you the hex value for a color in the 601/709 (TV and PC range)? Something like this but in YUV: http://www.w3schools.com/tags/ref_colorpicker.asp I know AvsPmod displays YUV values but it does not have a color picker. There's the also the color presets page in the wiki but colors are for RGB. Edit: Blankclip has the color_yuv parameter but what is it based on? 601 or 709?

Reel.Deel Registered User Join Date: Mar 2012 Location: Texas Posts: 1,664	Yeah, I saw that page while searching yesterday but what gets me is the slight color difference when using a 709 matrix. So I was looking for a something similar to that can tell me the correct value based on the matrix that I want to use.

Reel.Deel Registered User Join Date: Mar 2012 Location: Texas Posts: 1,664	I'm wondering how can I use RGB_2_YUV(post #4) to feed the color_yuv argument of Blankclip? Using Hex(RGB_2_YUV($191970, "Rec601")) returns "2ea67a" but it's missing $ and it's also a string.

vivan /人 ◕ ‿‿ ◕ 人\ Join Date: May 2011 Location: Russia Posts: 643	But you just don't need Hex. Code: BlankClip(pixel_type="YV12", color_yuv=RGB_2_YUV($191970, "Rec601")) or why even use all of this when you can simply Code: BlankClip(pixel_type="YV12", color=$191970)

jmac698 Registered User Join Date: Jan 2006 Posts: 1,867	Yes the hex value you want to use depends on the matrix, a rule of thumb is to use rec709. The differences aren't large (compared to rec601) but noticeable in green objects.
