Hey what's up video editors?! It's Premiere Gal here and in this video I'm going to
teach you how to chroma key a green-screen shot using the Primatte
Studio effect in Adobe After Effects. I also want to let you know that if you
want to learn something specifically in my description box below I leave a time
coded breakdown of each thing that I cover in the tutorial so if you need to
skip ahead you can certainly do that using the time codes below. Primatte
Studio is just one part of continuum by BorisFX. It's known as the Swiss
Army knife of plugins because there are so many things you can do with it from
image restoration, extruded text and more But in this video I'm just going to show
you how to use the Primatte Studio to achieve a professional chroma key in
just minutes. Now before I dive in I just want to reiterate that Primatte studio is
an award-winning software used for compositing in TV shows like Silicon
Valley, The Man in the High Castle, and films like Ghostbusters, Spiderman, Harry
Potter and much much more so here we are inside of Adobe After
Effects CC and in my composition I have this green screen shot of this young
woman and a background replacement. I downloaded both of these from Pond5's
stock library. In the effects panel I will search for Primatte Studio. Let's
drag and drop the BCC Primatte studio onto the green screen footage. Now the
special part about Primatte is that it comes with a special user interface also
called the UI which makes the chroma key process much easier. To start simply
check Auto analyze immediately the green background is gone and we see the
background layer but because the green screen background wasn't perfectly even
as it rarely is there are still some highlights and green tints we need to
clean up. So let's change it from final composite to matte status. You can see
that there's a whole lot of gray area in the background and gray is not good
because it means it's partly translucent and we want it to be completely
transparent, black. So to fix this make sure that the
clean background is selected then just click on the rectangle tool from the UI
to highlight areas of grey to remove it and it turns black. Isn't that easy?
Immediately the grey turns to black so now let's work on the foreground we can
see that there's grey spots there so let's clean it first select clean FG
which stands for foreground and using the rectangle tool you can select
portions of the foreground on the model to remove the grey. You can also zoom in
and use the point tool from the UI to get more accurate cleaning when we zoom
out you will see that some grey has come back to the background and now this is
when it becomes a bit of a battle between the foreground and the
background it's okay to have some grey dots here and there but you don't want
huge spots like we have in the background to get rid of these big areas
let's use the outside mask tool with Mocha Pro which comes with Continuum.
From the drop-down simply select Mocha Mask then select the
Mocha logo which will open up Mocha Pro and here we're going to use the X-spline
tool to draw a mask around that background area then hit save and close
and now you can see that problem area is gone. So let's change it back to final
composite and you can see that there's a slight green spill on the edge of the
model let's use spill sponge to remove areas of green spill now I'm going to
use the point tool and simply draw over the green and then voila the green is
gone I mean it's really easy to do but now around the edges of her hair you can
also see that we lost a bit of detail so let's restore some of that data let's
change it back to "Matte Status" then click on "restore detail" function and use the
point tool and the "Detail+" tool to just bring back a slight bit of detail
now notice that it also brought out a slight bit of the background but no
worries just to fix that we're going to create another mocha mask using mocha
Pro around that problem area so I'm just going to draw another mask using the
explained tool and then hit save now let's switch to final composite and I'll
show you one more tool, Light Wrap. over inthe effects controls check the box next
to Light Wrap. Next we want to select the background layer we want to grab light
information from. Now from the UI select Light Wrap on black (LW on Black) and here you will
just see the light wrap around the model now we can adjust the parameters such as
lightness which will add more white light around the edges so let's just
increase that slightly we don't want it too much and then softness is good to
use if we want to fill in some lost detail so I'll increase that to 20 then
width is how wide the Wrap is we don't want it to be too wide so I'm going to
set it to 20 now let's choose an overlay mode and it just depends on the scene
but I found that the lighten mode works best in this case. And then let's mix the
original at 50% as it gives it more realism.Now let's switch it back to
final composite and I'll turn the light wrap feature on and off and you can see
that the light wrap just added a nice little touch of light from the
background. As a final touch I did apply a BCC color balance to the model layer
and added five points of red back in to counterbalance the green. I hope that you
guys enjoyed this introduction to Continuum there's a lot more to explore
and let me just play it back and hit the effects on and off so you can see what
it looked like before and after we applied the Primatte Studio. If you want
