WEBVTT 1 00:00:00.000 --> 00:00:01.649 Now you know to remove green screen, 2 00:00:01.649 --> 00:00:05.448 but let's learn how to properly add a background. 3 00:00:05.448 --> 00:00:07.722 First, let's deal with the dog, 4 00:00:07.722 --> 00:00:09.981 adding a realistic background 5 00:00:09.981 --> 00:00:12.213 and making it look realistic. 6 00:00:12.213 --> 00:00:15.433 First, we're going to put the green screen dog on track two, 7 00:00:15.433 --> 00:00:19.370 then let's find this park movie video, 8 00:00:19.370 --> 00:00:22.537 and put it right behind, on layer one. 9 00:00:23.759 --> 00:00:25.083 I'm gonna zoom in here. 10 00:00:25.083 --> 00:00:27.469 This park video is not going to match the entire length 11 00:00:27.469 --> 00:00:28.954 of the dog video, 12 00:00:28.954 --> 00:00:31.004 so we can just trim off this last part 13 00:00:31.004 --> 00:00:32.209 of the dog video 14 00:00:32.209 --> 00:00:35.588 using the Razor Blade tool and deleting. 15 00:00:35.588 --> 00:00:39.043 Right away we can say that this doesn't look quite natural. 16 00:00:39.043 --> 00:00:41.236 For me, the background video does not match 17 00:00:41.236 --> 00:00:42.415 the size of the dog 18 00:00:42.415 --> 00:00:46.284 because I'm using the full resolution park.mov file, 19 00:00:46.284 --> 00:00:48.442 which is 1920x1080, 20 00:00:48.442 --> 00:00:52.909 where as the green screen dog video is only 1280x720. 21 00:00:52.909 --> 00:00:54.590 Its going to be different for you 22 00:00:54.590 --> 00:00:56.442 because I compressed them for the course, 23 00:00:56.442 --> 00:01:00.359 but note that a quick way to resize any footage 24 00:01:01.553 --> 00:01:03.193 to match the size of the sequence 25 00:01:03.193 --> 00:01:05.009 is by right-clicking, 26 00:01:05.009 --> 00:01:07.314 saying scale to frame size. 27 00:01:07.314 --> 00:01:10.796 If I turn off the dog and I do that again, 28 00:01:10.796 --> 00:01:14.646 you'll see that it automatically fits the screen size. 29 00:01:14.646 --> 00:01:18.325 So, right-click, scale to frame size. 30 00:01:18.325 --> 00:01:19.897 Now, we can adjust our dog. 31 00:01:19.897 --> 00:01:22.855 The dog looks too big for this background, 32 00:01:22.855 --> 00:01:25.490 so we can select our dog, double-click him 33 00:01:25.490 --> 00:01:28.011 in our programme monitor, 34 00:01:28.011 --> 00:01:29.765 then we can just resize. 35 00:01:29.765 --> 00:01:31.484 Let's try to make it look like this dog 36 00:01:31.484 --> 00:01:33.762 is the right size, 37 00:01:33.762 --> 00:01:36.820 and we can put him somewhere that makes sense. 38 00:01:36.820 --> 00:01:40.680 So, let's just put him in the bottom left corner. 39 00:01:40.680 --> 00:01:42.355 So, still looks pretty big, 40 00:01:42.355 --> 00:01:45.944 but that looks more, or less, normal. 41 00:01:45.944 --> 00:01:48.221 The next thing we want to do is match 42 00:01:48.221 --> 00:01:51.894 the colour temperature and the colour correction 43 00:01:51.894 --> 00:01:54.377 of the background to our dog. 44 00:01:54.377 --> 00:01:56.947 Our dog looks a little bit green. 45 00:01:56.947 --> 00:02:00.081 So, we can go into the Effects controls, 46 00:02:00.081 --> 00:02:01.494 and under the Ultra Key Effect, 47 00:02:01.494 --> 00:02:05.193 there actually is some colour correction options. 48 00:02:05.193 --> 00:02:07.812 You can even colour correct this in Lumetri Colour, 49 00:02:07.812 --> 00:02:09.010 if you want, 50 00:02:09.010 --> 00:02:11.715 but might as well just use the simple options 51 00:02:11.715 --> 00:02:12.752 in the Ultra Key, 52 00:02:12.752 --> 00:02:13.682 if they work. 53 00:02:13.682 --> 00:02:16.041 The hue, if we drag this to the right, 54 00:02:16.041 --> 00:02:19.396 will turn it more green, and then blue. 55 00:02:19.396 --> 00:02:22.862 Then if we go to the left its going to get more orange, 56 00:02:22.862 --> 00:02:25.596 reddish orange, and then purple. 57 00:02:25.596 --> 00:02:27.604 So, we don't want to go too far with it, 58 00:02:27.604 --> 00:02:30.087 but we can just go just a little bit. 59 00:02:30.087 --> 00:02:32.420 Maybe negative eight, or so. 60 00:02:34.297 --> 00:02:36.402 And Luminous, this is going to be the brightness, 61 00:02:36.402 --> 00:02:38.044 but also the contrast. 62 00:02:38.044 --> 00:02:41.621 We can decrease just a little bit to match 63 00:02:41.621 --> 00:02:44.216 the lighting in the background. 64 00:02:44.216 --> 00:02:46.625 This already looks a little bit better. 65 00:02:46.625 --> 00:02:48.980 One thing that's going on in the background, though, 66 00:02:48.980 --> 00:02:51.878 that's not happening with our green screen dog is 67 00:02:51.878 --> 00:02:54.666 all these subjects, or objects, 68 00:02:54.666 --> 00:02:56.053 the trees, the light post, 69 00:02:56.053 --> 00:02:58.328 they create shadows in this environment, 70 00:02:58.328 --> 00:03:01.503 So, let's go ahead and add a shadow to our dog. 71 00:03:01.503 --> 00:03:04.212 In the Effects, search for Shadow, 72 00:03:04.212 --> 00:03:06.880 and you'll find Drop Shadow. 73 00:03:06.880 --> 00:03:10.284 Let's take that onto our green screen dog. 74 00:03:10.284 --> 00:03:14.041 Then go down the Drop Shadow options, 75 00:03:14.041 --> 00:03:15.717 and if we increase the distance, 76 00:03:15.717 --> 00:03:18.644 you can see where the shadow is. 77 00:03:18.644 --> 00:03:21.909 We're going to make it relatively far away, 78 00:03:21.909 --> 00:03:24.034 so we can see it on the grass. 79 00:03:24.034 --> 00:03:27.951 You play with the direction, just a little bit. 80 00:03:29.597 --> 00:03:31.605 Something, like so. 81 00:03:31.605 --> 00:03:35.331 And, maybe soften it up just a bit. 82 00:03:35.331 --> 00:03:37.264 It's not a hard shadow. 83 00:03:37.264 --> 00:03:39.557 You can also play with the opacity, 84 00:03:39.557 --> 00:03:43.317 if you want it to be a little bit darker, to stand out. 85 00:03:43.317 --> 00:03:45.866 You decrease the distance, 86 00:03:45.866 --> 00:03:47.366 just a little bit, 87 00:03:49.427 --> 00:03:51.984 and the direction, make it closer to the dog, 88 00:03:51.984 --> 00:03:53.790 something like that. 89 00:03:53.790 --> 00:03:56.031 Now, it looks more like our dog 90 00:03:56.031 --> 00:03:57.331 is a part of the environment, 91 00:03:57.331 --> 00:03:59.279 and when our dog moves, the shadow moves, 92 00:03:59.279 --> 00:04:01.675 and it actually looks like its a shadow 93 00:04:01.675 --> 00:04:04.581 on this grass, right here. 94 00:04:04.581 --> 00:04:05.679 So, that looks pretty good. 95 00:04:05.679 --> 00:04:08.144 So, the key things to do with adding a background 96 00:04:08.144 --> 00:04:11.094 are to make sure that the size of you subject 97 00:04:11.094 --> 00:04:12.804 and the background matches. 98 00:04:12.804 --> 00:04:16.089 Then make sure that the colour correction 99 00:04:16.089 --> 00:04:17.772 and colour temperature match. 100 00:04:17.772 --> 00:04:21.856 Then lastly, add a shadow to make your subject 101 00:04:21.856 --> 00:04:25.348 feel as if they're a part of the background. 102 00:04:25.348 --> 00:04:28.488 If you're not using a realistic background, 103 00:04:28.488 --> 00:04:30.944 or you don't care about it looking like its matching, 104 00:04:30.944 --> 00:04:32.825 that's okay, too. 105 00:04:32.825 --> 00:04:35.636 We have this light curtains horizontal clip, 106 00:04:35.636 --> 00:04:39.727 which is just a background that I created in After Effects, 107 00:04:39.727 --> 00:04:43.724 And, this is something that you can use for any project, 108 00:04:43.724 --> 00:04:45.922 any green screen project. 109 00:04:45.922 --> 00:04:47.487 And, if I put this underneath me, 110 00:04:47.487 --> 00:04:51.808 you can see that its abstract, but its kinda cool. 111 00:04:51.808 --> 00:04:55.566 Adding a drop shadow, actually will help this video too, 112 00:04:55.566 --> 00:04:58.780 so I'm gonna do that, add a Drop Shadow, 113 00:04:58.780 --> 00:05:00.768 and make it a little bit bigger. 114 00:05:00.768 --> 00:05:02.299 So, distance, a little bit bigger, 115 00:05:02.299 --> 00:05:03.738 and the softness. 116 00:05:03.738 --> 00:05:06.016 I don't like the hard edge shadows, that much. 117 00:05:06.016 --> 00:05:10.245 I like a bit more distance, but making it soft. 118 00:05:10.245 --> 00:05:12.189 And, that just looks like it was 119 00:05:12.189 --> 00:05:13.862 kind of like an actual background, 120 00:05:13.862 --> 00:05:16.862 and that my shadow is casting on it. 121 00:05:18.022 --> 00:05:20.981 Now that we've edit out the green screen, 122 00:05:20.981 --> 00:05:23.932 we can actually increase the size of this video, 123 00:05:23.932 --> 00:05:26.929 just a little bit or even move it around, 124 00:05:26.929 --> 00:05:30.015 if we want to, say move me right here while I'm talking. 125 00:05:30.015 --> 00:05:32.138 And, then we can have titles pop-up here 126 00:05:32.138 --> 00:05:35.083 since this is one of my course videos, 127 00:05:35.083 --> 00:05:37.819 or add other graphics or anything like that. 128 00:05:37.819 --> 00:05:39.787 Cool, so that's a bit about 129 00:05:39.787 --> 00:05:41.499 adding backgrounds to your videos. 130 00:05:41.499 --> 00:05:43.151 If you have any questions, let me know. 131 00:05:43.151 --> 00:05:45.602 Otherwise, we'll see you another lesson.
