How to Use Green Screen in iMovie
Hey everyone. In today's I movie video, I want to show you how to deal with green screen clips inside of I movies actually built into the movie, but it's a little bit hidden. So I wanted to make this video to show you exactly how to find the effect and then a couple of other things you got to do with color to make sure everything matches.
Now, if you're doing this for very professional reasons, like if you're making TV commercials or if you're making a movie I'm movies, definitely not the tool for that. You shouldn't use Adobe premier or Adobe after effects for doing any green screen work. I'm not going to cover that in this video, but I do have a trial link to Adobe creative cloud and then you could watch a tutorial on that if this is really for high-end work for basic work, I'm always, actually pretty good at dealing with green screen here I am inside of I movie and I'm going to bring in my. Clip here, my green screen and this also worked with the blue screen too. If your background is blue and I went ahead and downloaded one here.
So I'm going to go ahead and select this clip and press import. Now, this from pixels.com, and you could actually get the same clip if you want to try this out. So I'll leave the link to pixelz.com in the description and then with this clip, this is all you have to do select it, and then bring it down here.
To this area, which is your timeline. Now, if you want to make any edits to this clip, you could obviously stretch it out or reduce the length of the clip, bring the endpoint in, and if you haven't watched my other video on using I movie, and this is your first time using a movie, make sure you watch the beginner's guide and I do have a full course on I movie on you to me, and you can learn everything there is to know about. I movie there. But here's the problem. When you add it here, there are no settings. You could look at all these different settings on top none of them saying anything about the green screen. Well, there's one thing we have to do.
We have to bring in our background first. What is going to be the background underneath this green screen? I'm going to show you two different ways. You could do this. You could go to the backgrounds, tap here and they have a bunch of backgrounds here, mostly simple colors here at some maps, but I'll show you how to bring your own background to all start with one of these.
We'll just select this one, for example, and bring it down to your timeline and make sure this is the same length as your video clips. So I'm going to stretch it out. Now, they both match. Now your background that you brought in has to be underneath the green. So, what you need to do is you need to bring your background underneath.
So if I grab it and I bring it under this, push this over. So I'm just going to grab this and put it on top. Basically, the order needs to be like this background first den your green screen on top of that. Now, if you select the top, you have another option right here. This option is for cutaways and overlays.
If I select it is set to cutaways right now, but if I press this dropdown, I now get a green or blue screen. If I select this option automatically, it removes the green for me creating this nice green-screen effect, but we're not done yet. Because a lot of times it will not get it right the first time. So you could play around with one of these settings.
There is softness and softness sometimes is helpful right now. It's not really doing anything, but if I go all the way you see, it's kind of keying out more of her hair, that's called King when you remove a color. So in this case, I'm okay with where this was by default in the middle. That, you have cleanups.
So let me show you a couple of settings here. This one lets you crop the image. Okay, so I'm actually going to crop the top part of the video. You see what the cropping is doing. You basically want to crop everything that is not the person. So I'm going to bring it in into it a little bit more. I could go through it, make sure she doesn't cross any of the sections where I cropped in, because if she does, basically, it's going to cut her off like this.
So we don't want to crop in too much, but this is sometimes useful. Sometimes you don't have to do it, but you'll notice sometimes there are areas here that this way you don't have to worry about, then you have to clean up. If you see any green or blue in sections that are outside, you could go ahead and basically erase them.
This is a racer tool, but you don't want to do this to your person because he will just make them disappear. Okay, and if you make a mistake, just command or control Z brings things back. Okay, that's all you have to do with a green or blue screen, and we're still not done yet. We are going to actually make sure the colors match.
So to do that, I'm going to select my background this time and there's an option here. If you come up here with your background selected called clip filter, select this, and then on their clip filter, select this option right here and you could add some clip filters here to try to match the different clips here.
If you don't want to use these preexisting filters, this is probably a better option too right here color correction. You could just go ahead and make adjustments. Like if your person is warmer or more orange, you could go ahead and do that to your background. If it's cooler, you could bring it down. It really depends.
You're just trying to match the background and the person in front of the background to kind of be in the same world by adjusting some of these colors and there's this option over here that lets you do all of this kind of automatically if you select it and press match color, what it lets you do is the background selected.
But now I want to click something from the foreground, which is my person. So I could bring in my eyedrop tool, you see that little eye drop icon and I'll select. My foreground and it's going to do a good job matching the two. So this is what I would go with, but I want it to show you the filter and the manual option, but the matching color seems to really work well, and then press the checkmark.
Now, let me show you how to actually do this with a background that is not the ones that are in IB. You want to bring your own this time. So let's go over here, back to the media tab and in the media folder, you could press this import arrow, and it's going to let you import from your download folder. Now, let me just show you where I get my backgrounds and I use Shutterstock because they got the best possible background pixels. Usually doesn't give me the green screen backgrounds that I'm looking for. So I do actually buy them from shutter stock and I have a lot of these especially for videos that I make where the office needs to be a background. These basically what's nice about them is they come blurred.
So blurred background just makes everything look more cinematic and they have a ton of different ones. So I just looked up off this background and I bought maybe 10, 15 different versions of these, like these without people in it. That's what you want. You don't want people in it. This is kind of nice, but I usually get these blurry ones and you could try it out.
You could press download and try it out before you buy it. But I already bought one. So I'm going to go ahead and import it in right now. So I'll go back to I move you over here. And I'm going to press this arrow and bring it in and I have this shutter stock image on my desktop and I'm going to press import selected down here and so all I have now is the green screen and that image. Now, if I just drag the image, I could do the same thing if I didn't have this background. But if you drop it on top of the background, it lets you replace it right here. So I could just replace it and then it's gonna. Let me stretch it out. So when there is no background, by the way, it's going to look black like that.
So I'm going to make sure I grabbed the end here and stretch it out to match my clip lengthier and it looks like you added some kind of an effect to it. So I'm going to select it and it looks like you added this crop effect. So if you select crop and make sure it's just crop to fit here and then press the checkmark by default, when you add an image, he adds a Ken burns effect.
If you add a video, it doesn't do that though. I'll press the checkmark. Now, this is my office background. Now again, I need to match the color. So I'm going to select a new background image I brought in. I'm going to come up here and I'm going to select this option right here to match color, so choose match color and then I'm going to go back with my eyedropper tool and choose the person and you could see made the background much warmer here and then press checkmark to apply that and now it looks a lot better and if the size wasn't right select this option right here, and then come up to the crop filter here, and then you could actually crop this however you want.
It doesn't have to be how a crop the by default if you need to zoom in more. Go ahead and crop it this way, press the checkmark and it's going to apply that zoom to your background to make sure it fits better. Now, it doesn't fit quite right, because now she looks too small compared to the background.
So I'm going to go ahead and do that and bring it back to how it was. So it was working fine. And to really get this looking perfect. What you really need to do is make sure you light your person with some idea of what the background is going to be, because if you know what the background is going to be.
Then the light can come from the same direction and things like that. But if you're only doing this in the edit, just pick a background that matches the direction of the lighting, or in this case, the windows are in the back. So it's okay that she has shadows on this side and the lights coming from this side, he actually matches this world and when you're happy with your edits, as usual, go to file and then go to share and then choose YouTube or Facebook here to get this export dialogue box. Make sure you select the largest format. 4k, for example, in this case, and then go ahead and export your movie and that's everything you need to do inside a buy movie to get a good green screen result or blue screen results.
But like I said, in the beginning, if you're doing this for professional reasons, I recommend moving to Adobe products. Adobe premiere actually does a really good job with a filter. It has a built-in. But it gives you a ton of options with what you could do with your green screen. I hope you found this useful and make sure you check out my course on a movie where I covered.
Literally, everything I'm will be, has to offer you step-by-step for a beginner to advance all in one course, which's available in the link below. Thanks again, and I'll see you next time.
