hey what's going on everyone so more progress in the film room you can say I have the frame for what will be eventually a green-screen will be filming most of our like how-to and instructional informative videos in here and I think some of the more hands-on stuff we'll probably do on this desk but you want to do is stand about three to four feet in front of the green screen itself so that you're not you know pressed against it and creating a shadow which will be really bad for when you're trying to I use ultra key a chroma key whatever to change the color of the background and if we're going to be using 4k and was gonna crop the image just a little bit so yeah you can see right inside the frame and that's the point so we're gonna need that green screen itself which is over here alright so this is what is known as muslin this is kind of like a bed sheet of sorts but it's pretty thick it's actually really heavy too and you want this to be not transparent at all because when you do go into editing later on and you find that it is transparent you have weird colors kind of washed out in the background assuming that your wall is not just a uniform color then you're gonna have a really bad time in production now rule number one I'm not gonna practice what I preach because I don't have one with me I just you know I could just moved into here and I still have a lot of stuff to buy you want to iron this you want this to be as flat as possible you don't want any wrinkles because those will create micro shadows and again very hard to get out post filming so this has just a little opening a little speed that goes all the way through and we're gonna thread this part up top on the bar all the way across well let it hang down now to compensate for the lack of an iron I'm gonna hope these clips reach on these you know these are these are kind of sure they're not sticking out very far from the pole and I think that the frame is 10 feet wide and the muscle has only 9 feet wide but yeah whatever worst case I'll just take it down later and iron it but I do want to set it up and see kind of what it looks like start playing around with the ultra key effect in Adobe Premiere Pro and get used to making things look super fancy so that further ado let's go ahead and set this thing up all right so after some ironing which I didn't bother filming because you know who wants to watch them on that iron something I've got this thing pretty much the way I want it now the lights aren't super powerful for this I was hoping they'd be a bit brighter in here they're not which means that there's a slight shadow here in the middle and you're probably wondering why the camera is so close actually a macro little lens fitted to the front of Sarabhai the autofocus to the front of this camera so I can stand you know but like a foot and a half away from the lens in my whole body will be in the shot and just because it's a wide-angle lens of sorts so if I stand kind of you know there about I'd say a foot and a half maybe to two feet away from the lens then there isn't a shadow generated behind me there's a slight one but we'll talk about that in a second ultra key with premiere and the lights are far enough apart that the shadows really don't show up and tell about a foot away from the muslin so I think it's kind of weird saying muslin it sounds awfully close to Muslim and then I feel really weird I think that if I use the center light here I'll turn that on and it should brighten up the the foreground and that's exactly what I'm looking for to keep me bright because these lights are pretty far away from me so what I'm gonna do I'm gonna go ahead and insert the SD card and I'm gonna start filming from the other side so that you can watch the screen kind of see what things look like that way you have an idea of you know how bright things need to be in the background you can see right now I just kind of zoom in on this screen it's really awkward doing like a two camera thing here so the background is is a decently lit I'm not too bright right now because the lights aren't shining directly on me so I can do is turn on this front light and things will brighten up lots a little too bright a little overexposed there things will brighten up in the foreground I look super pasty on that screen but I promise you I'm not I'm not overexposed in real life and we'll go ahead and start filming so what we'll do is we'll take this footage and we will throw it into premiere and you'll be able to see I'll just capture my screen they're able to see exactly what I do to get rid of the green background behind me and instead replace it with like black or gray well if I don't want to use black somewhere in a black shirt - so - so maybe we can do like a gray color or just completely you know go out there with like pink or some thing but the whole point is as long as it's evenly lit and it's not like to in focus you kind of want to blur the background out and you don't want a lot of shadows you also don't want to move super fast if I like wave my hand back and forth in a premiere you'll be able to see just slight grains of green that's because the ultra key tool can't keep up with those fast motion so when you're standing in front of a green screen it's really only good for talking and and slow movements movements are predictable really fast ones will pose a problem for the software all right now we're gonna cut this SD card let's bring it back with us turn this light off because it's all battery-powered right now and we will plug in the SD card all right you see I am this was my first test clip right here's the second one so I'm going to switch now to the screen capture so you'll see that instead of this awkward camera facing a screen alright so we have our clip on the desktop doesn't matter where you put it just keep things nice and orderly so you know exactly where to go if you want your resources at your fingertips we're gonna open up Premiere Pro and I'm gonna show you exactly what to do to start working with your green screen so I have a previous video clip here or a previous project I want to open up slide the clip into the timeline and then we're gonna click effects up top and I'm going to go to video effects and key and then we're gonna left-click on ultra Keys slide it over to the clip and nothing's gonna happen at first because what we have to do is click this tool on the left side a key color we're gonna use that little drop tool and we want to select an area in this clip window that is pretty green pretty kind of standard throughout you don't want a darker shade of green because then it'll start warping the lighter colors and there seems to be a lighter distribution here than there is dark also you can kind of see the shadow behind my head that's not good so we need to adjust our lights of it to get rid of that or I need to stand further away from the green screen so let's select a pretty standard color here this looks to be pretty good and there you go look boom so we have a black background now but it's not perfect you can see we have some light shades in here if you have a muslin especially you're gonna have these issues unless your lighting is just perfect spot-on or unless you're standing really far away from the green-screen so what I suggest doing come over to the left matte clean up we can soften things that'll kind of better distribute the the shades of light and then midpoint we can jump that all the way up and then contrast which will help with a black background boom now it's almost all completely gone and we will watch the playback now to see if it is in fact good enough for production now one thing I want to point out like I said earlier because my hands are moving pretty fast when you'll see they're just hanging in front of the green screen you might see a bit of a green shade around my fingers if they're moving very fast that's because the ultra key tools having problems with interpolating that green and changing it to black especially when it's happening for a split second so when you're standing in front of a green screen like this be sure not to move super fast I can see what I'm doing there with my hand it's you just get the idea that there's something that's not black behind me it's it's green and that's the downfall of using a green screen technology like this it's not perfect just don't move super fast and you shouldn't have any major issues another thing I want to do is check hardware utilization I want to see if this is using the graphics card at all I'm not sure then never use this tool so while we are in playback let's check the CP utilization a few cores are being used pretty heavily it's there on 30 40 percent that's pretty standard though I mean there are a few extra percentage points here for using the electric key effect but not too bad and on the graphics card side we have utilization here of a whopping 2% all right now this point I should clarify what we're really doing with the ultra key tool is deleting the background in essence what we're doing is selecting the color that we want deleted in ultra key is rendering that background basically like a blank image and a PNG file so we don't have anything now behind me or close to anything I would say that these shadows are gonna be an issue but what we can do instead of just having a black plain background is sliding in an image like this one here now look at there your boys semi-transparent with a shirt because we're a bit aggressive with the with the settings over here to the left so what we can do instead we can choose some presets aggressive is pretty good it's not too bad anymore used to be pretty bad but now it's not too bad you can see there my shirt is good let's go ahead and play back and see how accurate things look oh yeah looking great and we're not seeing any green smudges or dots around my hair that's usually where it becomes obvious this is pretty good you can see when I move my hands there's a slight green tint that's just something you'll be a pickup in production again a downfall of using a low-quality setup here but this should be okay for most of what I do well there you have it I will say pretty simple to set up I've never worked with a green-screen before and the software is fairly forgiving so even if you don't have a perfect like production setup perfect green-screen if you're not painting a wall and it's super smooth and and evenly lit across the entire canvas you can still probably get away with some some of those errors in Premiere Pro especially with the ultra key tool but chroma key in general is pretty good now the software's in a long way and it is fairly forgiving for those who are wondering I have the products linked in the video description for this setup here spend about a hundred bucks on the green-screen frame and all it's a pretty pretty good investment I would say the muslin is pretty thick I wouldn't recommend going with a cheap one because they are transparent that could pose a problem in production and kind of working with it now I can see why because if the light's not evenly distributed and then like you have like a semi dark wall or her pain to your walls aren't very smooth or maybe have something behind the wall then you're gonna have a pretty rough time in software like premiere if you liked this video be sure to give this one a thumbs up I appreciate it thumbs down for the opposite key to subscribe but if you haven't written stay tuned for more content like this don't worry it won't be all on the green-screen it's not going to be super fake only use it when necessary this is science studio thanks for learning with us
