Vega Pro 17 and BCC chroma key

Hi,

On Vega Pro 17
i9
Super 2070 RTX
32Go

I try to make an audio spectrum so i use bcc chroma key on bcc scatterize in order to select with pipette a black rectangle it does not work.

Regards,

BCC Chroma Key is specifically designed for keying out green or blue screens and won’t work for keying out the color black. BCC Primatte Studio is more flexible but is still primarily intended for green/blue screening. In your case I’d suggest trying out BCC Linear Color Key or BCC Linear Luma Key instead for keying arbitrary colors. You can also use the standalone BCC Pixel Chooser effect and change Channel menu in the PixelChooser Matte param group to Key which enables another color range keyer but sounds like that would be overkill for your scenario.

Cheers,
Jason
