In this case with "Red - 240 or above"īecouse Green is less intensive(or equvivalent) then Red it's must make opacity pixel, BUT we set "Screen Balance" to 0 and. The value of saturation screen color will be compared with larger value. Pixel are full transperent.īut, when the "Screen Color" = Green - 240, Red -240 or above, Blue - 50. Becouse Green more intensive then Red it's do not any affect on the pixel. If i have a green background and "Screen Color" sample as the same color(Green - 240, Red - 50, Blue -20).Īnd i tweak "Screen Balance" parametr to 0. Keyer look at the saturation on screen color and compare with the same or above saturation and make full transparent screen. A balance ofĥ0% will measure the saturation from the average of the A balance of 100% means that the saturation willīe measured against the smallest of the other twoĪ balance of 0% means that the saturation will be measuredĪgainst the larger of the other two components. This is where the Screen Balance controlĬomes in. Primary component against a weighted average of the two Saturation is measured by comparing the intensity of the In doc from Foundary for AE, "Screen Balance": I asked for help and got an answer about Keylight(1.2) settings.īut i realy don't undestand, how "Screen Balance" work.
