Pleas make more funktions relatetd to the ColorKey tab then the "SetAlpha" accessable vie API calls.

I would like to change the LumaKey Fill/Key source more quickly than by mouse. I want to play Videofiles for dynamicaly reaveal effects on a source in a Layer PiP constelation. (reveal from dust while animate with merge) But as Mixes won't play videoclips automaticlay i rather choose an other clip player over NDI. For preventig black input if this key input goes doen i want to quickly change to none or a fallback immage stored as in input in vMix.

Administrating the color key parameters as well as quick select the presets would make vMix more soiutable for liveadjustement an allow thirdparty control hardware to integrate better.
