The plugin works great, however, I'm finding troubles with rendering custom(so not the examples from the readme) pixels transparent.

 

Does anyone know which values to use for primary and near red?

Thanks in advance

    We had this same issue last autumn.  Micah from BrightSign gave us this equation to calculate the colors.  As a side note, we found the ChromaLuma plugin pretty weak on the edge feathering and had halos quite a bit.

     

    Here is Micah's message to us:

    "You will have to find the RGB values of the color you want to key in, the Chroma and Luma Values per the script are Y-Cb-Cr, above is a method to change from one set of digital RGB values ( 0-255) to YCbCr values ( 0-255)."

     

    Cheers,
    Monica
