How To Use a Green Screen | Filmora Tutorial

what's up guys matt from filmora here have you ever wondered how big hollywood movies film in surreal environments or how the weatherman does a weather report well that's a green screen in this tutorial I'm going to show you a few different ways to do green screen from the cheapest to the most expensive option we will also cover how to film green screen backgrounds using green screen to replace computer screens and how to edit your green screen footage inflam aura when all is said and done you will learn the basics of setting up shooting and editing your green screen but before we get started let me share with you three fundamental concepts that I always like to keep in mind before shooting green street but filming green screen lighting is the most important aspect so you get the clearest result you have to light the green screen nice and evenly if you don't light it evenly that'll create different shades of green if you have different shades of green then you won't be able to fully key it out meaning you won't fully remove the green screen if the light on the green screen isn't even then it's going to result in different shades of green and those shades won't be removed because you can only remove one shade of green make sure there's some sort of separation between your subject and your green screen when it comes to placing the subject in front of the green screen they shouldn't be too close to it you don't want them to be casting a shadow on the green screen or that they're so close that the reflection of the green screen spills onto the subject spill is caused when the light from the green screen is bounced on to the subject this is something you want to be cautious of because if there's spill on your subject then you're gonna end up being out the spill on your subject this concept even though it sounds obvious is often forgotten but when filming green screen your subject shouldn't be green or they shouldn't be wearing anything green if your subject just wearing green or if there's any props or foreground or background elements that are green then they will get keyed out when you key out the green screen no matter what method software or camera when doing green screen I always go over these three methods before hitting record there have been times where I didn't do one or two of these methods and it didn't go very well and if it's not shot properly it ain't gonna key well if you've never done green screen before then I suggest that you get the cheapest option out there which is poster board I got this from the dollar store for less than a dollar the only downside to poster board is you can get messed up pretty easily you want to keep it in pristine condition because if you get any folds or tears or if any of the color comes off then it'll make the surface all uneven and you don't want that if the surface is uneven then it's going to create different shades on your poster when it comes to lighting poster board or just green screen in general the easiest thing you can do is head outside I love being outside so the best type of day to film a green screen is on an overcast day now on a day like this we have some breaks of sunshine so it might not quite work so your second best option is to find an area of shade to film your green screen so the reason you want an overcast day or to be in the shade is to have a nice even light on your green screen so you can see right now we're in the shade we got this nice even green there's no harsh shadows or anything like that the light doesn't change it's just this even green color look to it and that's what we want alright so now that we've got this taped up let's go over our three rules that we covered earlier on green screens so how is our lighting by the look of it it's pretty even I don't see any harsh shadows or anything on the green screen so this should be good so our second concept separation and avoiding spill let's talk about that a little bit now separation and avoiding spill based on where we have our subject it looks like there's no spill so this light here is nice and soft and even that's what we want we're not getting a whole lot of spill coming back so our final concept is avoiding green and as you can tell right now I am not wearing green so we are good shoot so it's a okay to shoot but this is the tricky part of being outside is that there is likely to be green somewhere like in the grass trees or somewhere in nature so make sure to find a good spot all right so everything checks off so let's shoot our green screen and today we're doing our green screen wasn't me all right that one well now with poster board it can be kind of small and annoying to work with when you got to transport it so if you want a larger green screen and more portability that I suggest you get a green piece of fabric so you can buy this from a film equipment store but you can also get it from a fabric store and it could be a tablecloth or even a blanket but enough of this let me show you what we use here at film or here at filmora we use this doohickey but it's pretty big and the most expensive option now for lighting we don't always have the luxury of going outside because it could be raining it could be the evening or if you just be cold but mainly because we want more control of the light so we choose to shoot green-screen in our studio so what type of lights do we use when shooting in green-screen we use LEDs so we've got two LEDs set up here and the reason for that is if we only had one we'd end up with a gradient where one side would be bright and one side would be dark so it would be really difficult to pull your green screen and remove it you'd only be able to remove part of it and the other half would still be green so you need to that way you can get a nice balance across your green screen we also like to use this diffusion here now if you don't know where this comes from generally you can find these in the reflectors so if you actually unzip your reflector you can pull this out so a nice thing a reason why we use this is to make the light nice and soft and even as well if we were to remove this as you can see here you can see shadows but if I put the diffusion in front shadows are gone right so we want that nice even light on a green screen and it'll make it easier for us to pull the green screen to remove it so we can see the background so now that we've lit our green screen and it's nice and even we can focus on the subject so it's very common to light the green screen separately from the subject so before we light our subject let's find a place to put them so that there's no spill coming from the green screen so this greenish light bouncing on down my face does spill as you can tell when I get further away from it it disappears and if I get closer it comes back so let's find a place for George further away from the green screen so when it comes to filming George we're gonna use two lights a key light and a hair light so now that our lighting setup is all ready to go we're gonna bring Jorge in let's see if he's ready to go hey Matt what is that it's my favorite green scarf doesn't it look great yeah you're gonna have to lose it all right now we're good okay now since we've got our footage let me show you how to edit it in filmora make sure you have some footage to key into the green screen anything will really do but we're just gonna pick some landscape footage if you don't have film or @ then you can try yours free by clicking on the link here or the description box below I'm gonna give you five seconds to do that well let's get started after you have started up filmora select full feature mode and then proceed to import the background videos and green screen footage to the media library drag and drop the green screen video clip to the editors picture and picture track and put the image you want behind the green screen clip in the track below it right-click the clip in the timeline and select the green screen option the picture and picture window will pop up and this is where you can preview your clip and key out certain colors before picking what color to key out find a good frame to work from on the right of this picture in picture window is a preview window this is where we can see the edits were making let's use the scrubber at the bottom to find a frame all right I like this brand now check the make parts of the clip transparent box with the mouse let's use the picker tool and select the color I want to Kio so in our case green now drag the slider to adjust the intensity level as you can tell this slider will affect the transparency of your clip let's play back our changes to see how it looks make sure you keep an eye on your subject in front of your green screen you may notice that some of your subject is cheedo if they are you will have to lower the intensity once you like how it looks click OK export it and your green screening is done all right that's my tutorial on how to film and edit green-screen backgrounds but we're not done yet have you ever wanted to put a video on a desktop computer screen or a TV but the video wasn't ready while a clever way of doing that is using one of them as a green-screen and then replacing the green-screen with the video later now this procedure is a little different from the three concepts that we've been talking about in this video they're still relevant but the subject of the shot is the green-screen itself so the first thing you want to do is go on to the computer screen that you're going to use and replace the wallpaper to a solid green image you can find this green image through Google Images or you can just make one yourself once your wallpaper is set it's time to shoot the screen if you want a person to sit in in front of the monitor then it should be fine just keep in mind or concept of separation and spill lastly let's make sure that the only green is on the screen and then you should be good to go now let me show you how to edit this in filmora for this green-screen part we'll be doing the same procedure as we did earlier in this video but what's different is how we put videos in the picture and picture tracks that's right tracks will need to after your footage is imported first thing you will do is place any video or just a video on the main track I suggest using a sample color because you can change the length of it to any size now let's take the video you want to put on the desktop screen on the first picture and picture track for now just leave it here we'll get back to this soon I will now take the video of my screen with the green screen wallpaper and put it on the second picture in picture track and use the green screen tool to key out the green once the green screen is gone go back to the video clip in the first picture and picture track and select it in the preview window you can see that it's highlighted you can now resize it to the size you want so I'll resize it to the size of the monitor well that's all you have to do in order to replace the screen of a computer once you're done with it and it all looks good export it well that's how to shoot and edit a green screen in filmora I just want you to know that green screens aren't limited to backgrounds or the color green green is the standard color because it doesn't match any natural skin tone or hair color you can technically use any color but make sure your subject isn't wearing it or the that color that you're keying out isn't in the foreground the background or any ground in the image hope this video helps you out and keep making videos don't forget to comment like and subscribe and tell us what you want to green screen we'll see you next time
