Hey Kian,

I believe your suggestion has a good chance of working. I am still working on this new approach. I believe I have the conversion down, but I am not sure if my Chroma Keying logic is good for handling RGB. I am also having to make a custom color plane combiner because I have to separate RGBA and A in order to convert back to YCbCr. The custom component I made combines YCbCr w/ Alpha. I will let you know if I get better results once I get it working.

Thanks,

Evan
