The last step is color correction and light wrap you get with the Foreground and Background controls. This process is a lot faster if you keep switching back and forth between the Combined Matte and Final Result display modes. When you get the edges as good as you can get it is time to tweak Screen Blur, then work through the Screen Matte settings. Then switching back and forth between Combined Matte, Screen Balance and Final Result will help you get these controls set up very quickly. The status viewing option is a great place to start when setting the Screen Gain and Screen Balance. Blue and Red is a good place to start, but you should try other colors. Changing the color of the outside edge and manipulating the Screen Gain and Screen Balance will show you how both these controls change the blending between colors. Status lets you see the ramp or feather of the alpha channel. Then I apply Keylight and set it up like this: 100% Blue halfway out and 100% red on the outside edge. When I am giving a demo of Keylight I start by creating an ellipse (circle) with a gradient fill. What sense in this comparison when green value alwayse greater? Please, help! Why i must compare this 2 other value? I must compare Green with less or more Green. What this compare it does? In both cases pixel are transparent. 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.
KEYLIGHT 1.2 SOFTEN EDGES FULL
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.
