How to chroma key piano keys


New Member
Hi there,

I hope someone here can help me out or point me in the right direction. I’m a piano teacher, I want my piano software keys as chroma key under my fingers. I have included a picture. Is this possible without painting my keys green or blue. I have played around with color key, chroma key and luma key but it’s not good enough because my hands are affected by these filters, is there an other way or do i really have to paint the keys :-(. Also included a link to the video.

thank you, regards Rik
