Hello! In today's lesson, we'll learn how to remove a green screen background in Premiere Pro. Let's create a new project. I'll call it "Green Screen". Click Okay. And I'm gonna go into the editing workspace here. So Window, Workspace, Editing, or just click on the Editing Workspace in the toolbar. If need be, I'll reset the workspace to it's saved layout. Let's import a green screen video clip. I'll right-click in Import. And I'll navigate to my media for that. In this green screen folder, I have Green Screen 2.mp4 And I'll import that. I could create a sequence by dragging and dropping it into the timeline. But, initially I wanna do some trimming on this. So, I'm gonna double-click on it to make it appear in the source monitor. So if I scroll through this footage you could see I'm gonna use the footage from the point where the glasses are off, right about there. I'll make an in-point here. And go to the point where the waving, and that's the end. So as you can see, this has been shot against a green background. And what I'm gonna do now, is put this into the timeline here from the end to the outpoint. This does not have any audio on it that I want, so I'll just drag the video portion into the timeline. So you can see it in the program window. I'll go the the effect controls and click on the clip, because I'm gonna scale it up a bit. The green screen didn't quite cover the whole background. So I'm gonna scale this up slightly and adjust the position, so bring that up like so, and then I will adjust it downwards. I'm gonna make sure my head's still visible there. There we are. So I made that initial adjustment on that. And now, since we're in the effects controls, we can go to the effects panel here, in the project panel, and I will type in Ultra, U-L-T, for Ultra Key, here it is. I'm gonna drag and drop this onto the green screen clip there. And I just wanna scrub head to the point where my hand is out there, my arm. When you do green screens, many times, you wanna make sure that the person doesn't go outside the area that you want to use. So I'm checking that there. You don't wanna eliminate that portion necessarily. So, this will be giving you a good idea, too, about how well the mask works. There's a little bit of motion blur in the waving hand. So, the first control for Ultra Key, we look here, is what's called Key Color. And, I'm gonna take this eye dropper, and I'm gonna bring it into the scene, and I'm just gonna click on a green area. There we go. So most of it turned black. I can see a little bit of tone in here, but this is something we're going to finesse once we make our initial green screen. And we can view different ways to see how well the green screen is working. So, I'm gonna go to the output setting which is currently set for Composite, which is the default. And the setting is at the default, which is called Default. I will change both of these to finesse this mask. So, I'm gonna click on Composite here, and I'll switch to Color Channel for a moment. And now you could see that it's turned gray in that area and there's still a little bit of tone, particularly in this area, as well. And, if I switch now the output to the Alpha Channel, you can actually see the mask that's being created. And so, any areas that are pure white, are showing through. Any areas that are black or gray, are being masked out. So, I may want to, I definitely will want to make adjustments to this because there's clearly still some tone in these areas. And so, I'm going to go to the aggressive method here, which helps a lot with making that mask. And then from here, I'm going to go down to Mat Generation, twirl that down. And I'll make some adjustments in here. So, since I can see some grays, I'll adjust the shadow, and I'm gonna drop that down a bit to get rid of those items. Now, I don't wanna go too far, because you see it's starting to pick up some highlights from, or from shadow areas over there. So, I have to find the sweet spot there. So scrub this forward a little bit. That's pretty good, it's pretty clean in the middle, there. And I can go further by adjusting the tolerance up to a hundred. And the pedestal, which will affect the bottom tones, also. I'm going to take that and bring that up, as well. And now you could see it is getting rid of a lot of that gray area there. So if I now switch back to Composite, let's see what we have going on there. The background looks more uniformly black. But again, remember I was getting this a little extra bit here. Where the green screen was rolled up. So I may wanna adjust my positions here. I'll go back to Composite to do that. And I'll just bring that over to the left. And then when I switch back to that, I should be able to get rid of that. Let's see, there, it's gone. And I do see a little touch of gray there, so I might readjust my pedestal and the shadow. Just a bit more. So, I can twirl that up at this point. Go back to Composite. And I need to be able to see, though, exactly how transparent and good this mask is. So I'm going to go here, and I'm going to create a new item here with this button. I'm going to choose a color mat. And click on it, and I'll make a red color mat. This will stand out pretty well. And I'll call it Red. I can take this, and I'm gonna drag this layer up to V2. And I'll click and drag the red underneath. And now I can bring it back here. And I'll click and drag it out to be the full-length of the clip as well. So now, I could scrub through and see how clean that background is. It's looking pretty good right now. Okay, so now that we've done that, I'm gonna go scrub out to that point where my fingers are showing there. There's a little bit of motion blur, and you could see some green around the edges there, which is a bit of the mat that it didn't quite get. So, I'm gonna twirl down to Mat Clean-Up. And we could use something like Choke, and I'll just adjust this very slowly as I scrub here. You could see it starts to reduce, squeeze in, or cut in, or choke the mat around the subject. And that tightens up the lines around there. So you have to be kind of judicious with this, because it's very quickly, you can make it look, you know, I have square fingers now. So, and I don't wanna loose too much of the hair, as well. So I'll try and find a sweet spot for that. Ended up around 41 here. Adjusting the mid-point and contrast might help a little bit, too, here. I'll just make some tweaks in there. And that could help as well, with that. So often, we'll make it too smoothed out. So it actually exasperate the problem if I were to do that, as you can see. I'll leave that alone. I'm gonna go down to Spill Suppression now. That you can get when you have someone photographed against the green screen, particularly if they have light-colored hair, or light-colored clothing. The green can actually spill, or wrap around the subject somewhat. And it'll show up in the hair, or the clothing, the light clothing, and sometimes even on the skin. So the spill suppression is there, and if you de-saturate a little bit, just a tiny bit, I'll go up to 54 here. What I kind of determined was a good level. And it just takes a way a little bit of saturation in the clip there, to remove some of that green. 'Cause it's de-saturating all the colors. The other controls here are used to fine-tune that. In this particular case, it looks like it'll be fine. Just with the de-saturate. I'm gonna leave the Color Correction options alone, because I need to add a background image in the next lesson. And so that's where I'll employ some of the color correction to match the color balance of the background image. So in this lesson, you've learned how to remove a green screen background in Premiere Pro. In the next lesson, we'll add a background image to the scene, and make some adjustments and corrections to make the scene look as believable as possible. Let's go check it out.
