  • Can you keep only black in footage and make everything else transparent?

    So i have this effect called unknoll, and it removes black from any footage. (obvious reasons why its useful) but i have footage that is a transition into black and i want to keep the black and remove the background footage. sooo i need everything to be transparent except black. i tried a few things, and got nowhere. does anyone know how to do this? is it possible?

    Use a luma key, set it to key out brighter and set the threshold low, 16.
