WEBVTT 1 00:00:00.722 --> 00:00:02.203 In this lesson, we're going to learn 2 00:00:02.203 --> 00:00:04.374 how to deal with green screen footage 3 00:00:04.374 --> 00:00:06.051 in Adobe Premiere Pro. 4 00:00:06.051 --> 00:00:08.902 Go ahead and find the green screen dog video 5 00:00:08.902 --> 00:00:12.153 and the green screen Phil video. 6 00:00:12.153 --> 00:00:14.975 You can see here that the green screen dog, 7 00:00:14.975 --> 00:00:16.444 when you're shooting, you want to have 8 00:00:16.444 --> 00:00:18.367 an evenly lit background. 9 00:00:18.367 --> 00:00:21.983 This is much more evenly lit than green screen Phil. 10 00:00:21.983 --> 00:00:24.043 It's a lot darker, and so this one 11 00:00:24.043 --> 00:00:27.083 is going to be a lot easier to fix 12 00:00:27.083 --> 00:00:28.747 or to remove the background, 13 00:00:28.747 --> 00:00:30.357 but I wanna walk you through this one 14 00:00:30.357 --> 00:00:34.012 to show you that you can remove the background 15 00:00:34.012 --> 00:00:36.539 from a difficult image. 16 00:00:36.539 --> 00:00:37.604 First thing's first. 17 00:00:37.604 --> 00:00:39.132 The first thing that I wanna do 18 00:00:39.132 --> 00:00:41.399 when I'm dealing with green screen footage 19 00:00:41.399 --> 00:00:43.895 is actually add the crop effect. 20 00:00:43.895 --> 00:00:47.282 In effects, you can search for crop under transform. 21 00:00:47.282 --> 00:00:49.745 Add that to your footage, and then crop 22 00:00:49.745 --> 00:00:52.861 into your subject as much as possible, 23 00:00:52.861 --> 00:00:55.020 wherever your subject is not. 24 00:00:55.020 --> 00:00:57.882 With this dog, who's sitting very still, 25 00:00:57.882 --> 00:01:01.394 I'm going to crop in the left and the right, 26 00:01:01.394 --> 00:01:03.497 and the top just a bit. 27 00:01:03.497 --> 00:01:06.214 What this is doing is helping Premiere Pro 28 00:01:06.214 --> 00:01:08.474 by basically automatically getting rid 29 00:01:08.474 --> 00:01:10.146 of this part of the background. 30 00:01:10.146 --> 00:01:12.058 The green screen effect that we're using, 31 00:01:12.058 --> 00:01:15.907 the ultra key doesn't have to worry about that at all. 32 00:01:15.907 --> 00:01:19.244 Let's do add that ultra key effect. 33 00:01:19.244 --> 00:01:22.482 It's the best keying effect in Premiere Pro. 34 00:01:22.482 --> 00:01:24.949 Drag that onto your video, 35 00:01:24.949 --> 00:01:27.828 and then we're going to take this key colour picker. 36 00:01:27.828 --> 00:01:29.502 Select this eyedropper. 37 00:01:29.502 --> 00:01:32.398 You can go anywhere on your green screen and pick it. 38 00:01:32.398 --> 00:01:35.127 I generally pick somewhere a little bit darker 39 00:01:35.127 --> 00:01:37.588 because I find that it's easier to make adjustments 40 00:01:37.588 --> 00:01:40.409 and fix the highlights of the green 41 00:01:40.409 --> 00:01:43.718 versus selecting a brighter part of the green 42 00:01:43.718 --> 00:01:45.529 and adjusting the darker part. 43 00:01:45.529 --> 00:01:46.719 Let's just pick something down here, 44 00:01:46.719 --> 00:01:48.583 it's a little bit darker. 45 00:01:48.583 --> 00:01:51.326 We still see a little bit of speckles, 46 00:01:51.326 --> 00:01:52.747 especially if you play through this, 47 00:01:52.747 --> 00:01:54.907 you can see speckles in the background, 48 00:01:54.907 --> 00:01:57.705 and so we need to get rid of some of those. 49 00:01:57.705 --> 00:02:00.278 With this shot, we can easily change the setting 50 00:02:00.278 --> 00:02:04.445 of the ultra key from default to aggressive, 51 00:02:05.484 --> 00:02:09.567 and that's going to automatically fix the issues. 52 00:02:10.814 --> 00:02:13.497 It's a very, very good key already. 53 00:02:13.497 --> 00:02:16.309 To make sure that it's a good key, change the output 54 00:02:16.309 --> 00:02:19.066 from composite to alpha channel 55 00:02:19.066 --> 00:02:22.149 and scrub through and see if there's any parts 56 00:02:22.149 --> 00:02:25.180 where you see shadows within the white, 57 00:02:25.180 --> 00:02:26.548 and I see a little bit. 58 00:02:26.548 --> 00:02:29.772 I'm gonna go here where I see some of those shadows. 59 00:02:29.772 --> 00:02:32.453 I'm going to go to matte generation, 60 00:02:32.453 --> 00:02:33.996 and then where the shadow is, 61 00:02:33.996 --> 00:02:37.230 I'm going to just increase that just a bit 62 00:02:37.230 --> 00:02:41.146 until those shadows disappear. 63 00:02:41.146 --> 00:02:42.494 Then, if that doesn't get all of them, 64 00:02:42.494 --> 00:02:43.760 I see a tiny one right there. 65 00:02:43.760 --> 00:02:45.910 It might be a little bit hard for you to see. 66 00:02:45.910 --> 00:02:49.198 You can play with the tolerance 67 00:02:49.198 --> 00:02:53.365 or the pedestal and see what that does. 68 00:02:56.160 --> 00:03:00.784 Increasing the pedestal seems to be helping out a lot. 69 00:03:00.784 --> 00:03:04.587 Still have a couple shadows right around here. 70 00:03:04.587 --> 00:03:07.235 Let's see if increasing the shadows even more helps. 71 00:03:07.235 --> 00:03:08.683 That seems to do that. 72 00:03:08.683 --> 00:03:10.798 You also wanna make sure that there's no speckles 73 00:03:10.798 --> 00:03:13.372 in the black, and if there are, 74 00:03:13.372 --> 00:03:15.733 you would adjust this highlight, 75 00:03:15.733 --> 00:03:17.233 and we're going to be using that 76 00:03:17.233 --> 00:03:20.176 for the green screen Phil shot in just a second, 77 00:03:20.176 --> 00:03:22.301 but if we go back from, 78 00:03:22.301 --> 00:03:24.757 I'll put alpha channel to composite. 79 00:03:24.757 --> 00:03:28.770 This is a good to go green screen shot of this dog, 80 00:03:28.770 --> 00:03:30.109 and we'll start adding backgrounds 81 00:03:30.109 --> 00:03:32.378 and talking about that in the next lesson. 82 00:03:32.378 --> 00:03:35.441 Let's jump over to the green screen Phil shot. 83 00:03:35.441 --> 00:03:39.481 The first thing we are going to do, again, is crop this. 84 00:03:39.481 --> 00:03:42.587 With the crop effect, I'm going to add it. 85 00:03:42.587 --> 00:03:45.087 I'm going to crop the left in. 86 00:03:46.031 --> 00:03:48.171 I'm going to crop the top in. 87 00:03:48.171 --> 00:03:49.484 We obviously have to get rid 88 00:03:49.484 --> 00:03:51.566 of the edges of this clip because 89 00:03:51.566 --> 00:03:55.733 this green screen didn't cover my entire background, 90 00:03:56.865 --> 00:03:59.491 and then crop in the right side just like that. 91 00:03:59.491 --> 00:04:01.471 As much as possible. 92 00:04:01.471 --> 00:04:03.083 When you're shooting, though, you have to be careful 93 00:04:03.083 --> 00:04:06.366 of moving your hands so that your hands don't go 94 00:04:06.366 --> 00:04:10.082 over the edge of the green screen. 95 00:04:10.082 --> 00:04:11.285 This looks pretty good. 96 00:04:11.285 --> 00:04:14.568 I might be able to drag in the left 97 00:04:14.568 --> 00:04:16.593 just a little bit more. 98 00:04:16.593 --> 00:04:17.565 Okay. 99 00:04:17.565 --> 00:04:19.982 Now, let's add the ultra key. 100 00:04:21.461 --> 00:04:24.056 We're gonna put the ultra key on our clip. 101 00:04:24.056 --> 00:04:25.799 We need to take our colour picker, 102 00:04:25.799 --> 00:04:28.616 choose somewhere down here in the darks. 103 00:04:28.616 --> 00:04:30.431 You still get a lot of 104 00:04:30.431 --> 00:04:34.203 the highlighted green screen appearing, 105 00:04:34.203 --> 00:04:37.199 The reason is because the lighting 106 00:04:37.199 --> 00:04:39.126 of the green screen was not amazing. 107 00:04:39.126 --> 00:04:39.964 This was a quick job. 108 00:04:39.964 --> 00:04:42.537 This was a test, and I didn't really 109 00:04:42.537 --> 00:04:45.549 put up actual lighting, and that's why it's so uneven, 110 00:04:45.549 --> 00:04:47.881 but we can still make this better. 111 00:04:47.881 --> 00:04:49.415 We're going to first change the setting 112 00:04:49.415 --> 00:04:51.196 from default to aggressive. 113 00:04:51.196 --> 00:04:53.415 That helps get rid of some of it, 114 00:04:53.415 --> 00:04:55.303 then we're going to go change 115 00:04:55.303 --> 00:04:57.420 from composite to alpha channel. 116 00:04:57.420 --> 00:05:00.776 Here, you can really see the speckles in the black. 117 00:05:00.776 --> 00:05:04.943 We're going to drop the highlights down all the way. 118 00:05:06.621 --> 00:05:08.454 Play with the shadows, 119 00:05:10.791 --> 00:05:12.345 and then play with the pedestal. 120 00:05:12.345 --> 00:05:14.345 Increasing the pedestal. 121 00:05:15.305 --> 00:05:16.655 Then we're just gonna go through, 122 00:05:16.655 --> 00:05:18.428 scrub through just a bit to make sure 123 00:05:18.428 --> 00:05:20.421 that there weren't any other spots 124 00:05:20.421 --> 00:05:22.855 where shadows are shining through 125 00:05:22.855 --> 00:05:27.076 either on my face or speckles in the background, 126 00:05:27.076 --> 00:05:29.746 and that seems to have done a really good job. 127 00:05:29.746 --> 00:05:31.205 Then I'm going to change this alpha channel 128 00:05:31.205 --> 00:05:32.932 back to composite. 129 00:05:32.932 --> 00:05:34.859 This looks really good. 130 00:05:34.859 --> 00:05:37.263 One thing I notice, it's very subtle, 131 00:05:37.263 --> 00:05:40.298 but I do see a little bit of a green edge 132 00:05:40.298 --> 00:05:43.379 around my hair, and we can really notice, 133 00:05:43.379 --> 00:05:45.962 and one thing I encourage you to do 134 00:05:45.962 --> 00:05:49.201 is actually add a white background while you are doing this 135 00:05:49.201 --> 00:05:52.242 just to make sure you're green screen is looking good. 136 00:05:52.242 --> 00:05:55.490 I'm going to click this new item button, 137 00:05:55.490 --> 00:05:59.607 go to colour matte, say okay, 138 00:05:59.607 --> 00:06:01.820 and select white. 139 00:06:01.820 --> 00:06:04.153 We'll call this white matte. 140 00:06:05.235 --> 00:06:07.463 Then I'm going to put this underneath 141 00:06:07.463 --> 00:06:09.463 my green screen footage. 142 00:06:11.385 --> 00:06:12.853 Looking pretty good. 143 00:06:12.853 --> 00:06:15.417 It's even harder, actually, to see that green edge 144 00:06:15.417 --> 00:06:17.136 with the white, so that's good. 145 00:06:17.136 --> 00:06:18.861 I'm just gonna go back to this shot 146 00:06:18.861 --> 00:06:22.490 with black background, and to fix that edge, 147 00:06:22.490 --> 00:06:23.835 there are a couple things. 148 00:06:23.835 --> 00:06:26.665 We can go down to matte clean up. 149 00:06:26.665 --> 00:06:28.159 The choke and the soften 150 00:06:28.159 --> 00:06:31.463 will actually increase or decrease the edge. 151 00:06:31.463 --> 00:06:33.567 Let me show you the alpha channel 152 00:06:33.567 --> 00:06:35.545 so you can see that better. 153 00:06:35.545 --> 00:06:38.755 Choke, soften, so increasing the choke, 154 00:06:38.755 --> 00:06:40.525 softening it up. 155 00:06:40.525 --> 00:06:43.699 It will make your edges a little bit more soft. 156 00:06:43.699 --> 00:06:45.424 With the white background, you can see 157 00:06:45.424 --> 00:06:47.051 that looks really funky. 158 00:06:47.051 --> 00:06:49.624 I would never go that much, but sometimes, 159 00:06:49.624 --> 00:06:52.111 if you do want to decrease the edges 160 00:06:52.111 --> 00:06:54.352 just a little bit, this can help. 161 00:06:54.352 --> 00:06:56.799 It's pretty hard to see the green edges 162 00:06:56.799 --> 00:06:58.140 with the white background, so I might 163 00:06:58.140 --> 00:07:00.797 not even need to do this, but it's good 164 00:07:00.797 --> 00:07:04.501 to know that when you do have some green highlights 165 00:07:04.501 --> 00:07:06.453 because of some green light bouncing 166 00:07:06.453 --> 00:07:09.656 off of the green screen, you can go to spill suppression 167 00:07:09.656 --> 00:07:12.813 and increase the desaturation just a little bit. 168 00:07:12.813 --> 00:07:14.082 If you go too far, you can see 169 00:07:14.082 --> 00:07:17.403 that the entire image becomes desaturated, 170 00:07:17.403 --> 00:07:21.013 but just doing it a little bit will help it a lot. 171 00:07:21.013 --> 00:07:23.899 This is how we remove green screen backgrounds 172 00:07:23.899 --> 00:07:24.852 in Premiere Pro. 173 00:07:24.852 --> 00:07:26.888 In the next lesson, we're going 174 00:07:26.888 --> 00:07:29.245 to be adding backgrounds and making it look good 175 00:07:29.245 --> 00:07:31.747 with a background, because this is just the first step, 176 00:07:31.747 --> 00:07:33.815 removing the background, now we have to add 177 00:07:33.815 --> 00:07:35.659 a background that we want, 178 00:07:35.659 --> 00:07:37.014 but make it look natural.
