Get only pure color with keyer

#1

I’m looking the way to keying only pure color, and animatable its parameter.

I testing with Keylight, Primatte, Ultimatte, and HSV keyer. I know that useful of keyed is extract a range of tones around color picked, but I need only get a unique pure color.

I have a idmatte rgb image, with no sub-sampling color pixels (in example, antialiasing), then I want set up a keyed operator to get only one color per frame.

The most close to I want find is HSV keyer, but this can’t animate amount parameter.

Keylight would be valid for I want to do, if Alpha Bias and Despil Bias be able to “turning off”

Hsvtool seems ok, if I put my alpha to “all” I have access to brightness,hue and saturation ajustments,

I tried with IDSelect_hub tool, and work also ok.

With HSVtool I must be to animate HueRange because change when I pick color from image, and if I not animate this parameter, I don’t see animated mask. Color range I see works ok that I have similar colors, but I need only get a exact color values.

HSVtool works for me! Thank you Mascou77!
