ATEM Mini Extreme - Setting up the Chroma Key

[Music] hi everybody Frank here welcome to my laboratory today I want to talk about chroma key now we have a few of the atem mini extremes out at the schools and I want to show you how to do a simple chroma key background some of the schools said well how can we adjust it so we don't have the fuzzy background I'm going to show you how to do that too so let's take a look and let's get started but before we do I want to show you something you'll notice behind me here see the shadow on the green screen and even back here I've got a shadow so what's key about and if you excuse the pun uh on green screens is even lighting okay I'm going to show you another green screen that I have behind on this wall so let me switch over here so here is my green screen behind me here and you can see it's nice and even and well lit so that's important okay that's in step number one now also we know that a lot of the schools have curtains uh blue curtains some have green curtains some are black but we can key on the blue and the green but not the black and the thing about keying with the curtains the problem is that they're fold the folds so and these are the folds you've got a lot of dark spots so we have been able to successfully do it but we have to stretch the curtain out so it's as even as possible okay so that's that's uh that's why we do recommend that you have an even background and a lot of the new schools are just painting the wall screen no curtain at all so we get rid of the fold so we when there have been some schools that actually just went out and bought paint Home Depot Lowe's and got some bright green there's no specific kind of green green but a bright green works really well and painted the walls bright green and that works too so let's get into it and I'll show you what I'm talking about so first we're going to look at the software controller now this is important because this is where you do a lot of your setups so if you look over here these are four keys that we're going to be using first thing I'm going to do is over here in this area it says Upstream key one that's the one we're going to work with there are actually Four Upstream keys but we will be working with Upstream key one now so here's where there's four tabs here there's Luma tab chroma key tab pattern and dve which is digital video effect and these are options that we'll we'll explore later but we don't really use the Luma key that's more for black and white so the chroma key here's we're going to have the tab open and now you're going to see your settings here's your settings here now I'm going to go and show you the begin we're going to work on key number one so what you have to do is you have to select what's called a fill source so we're going to use camera one and uh here's my camera one here's what we're going to be using with that really nice background so let's go back to our deck here okay so that's where you select there camera one because if you do the drop down you could you can fill it with all other options too camera one now what we have to do is we have to select the chroma key what's called a sample the the computer wants to know what color green you're going to be using so it could do its it it can do its its magic so I'm going to click on here it says chroma key sample now um what happens is this little box comes up over here is a little adjustment to make that box bigger smaller but that's about the good size right there so what you need to do and I know you can't see it but it'll pop up in the previous screen and what you do is you Mouse over this little box and where the color is you can turn that off and now here are your adjustments I want to show you how these work first up what I'm going to do is going to turn go over here and turn on the chroma key button right here and go on okay well obviously you could see that there's fuzzy right so that that is needs to be adjusted so here I'm going to show you how to adjust that now I'm actually going to make the adjustment but you'll see it'll clear up I'm going on what's called the key Edge so let me turn this off for a second here's where I'm going to adjust this thing here called key Edge and that's going to clean it up usually these don't do a whole lot but let's try it so I'm going to go back on here and I know you can't see it but you will and I'm going to go on key Edge I'm going to move it move it move it now you can now you can see it moving now right now look at the fuzzy it's getting cleaned up so let's go clear and say okay that looks pretty good so that looks pretty good I don't see any more fuzzies so I think we did it okay now that we've done that now here's where we say well okay well obviously I don't want that background now we can start choosing backgrounds so I'm going to go back I'm going to turn uh uh the key off so you can see what I'm doing over here well let me put let me put this guy over here there I am in the corner now so what I'm going to do over here is we have so we can select some backgrounds so right now I'm going to say well I want to look at either media player one media player two or I actually have a video that we can play through if we want so let's go let's go back to the software and I'm going to turn me off let's go back to Media and here is where we have the software control for the media pool now I have a lot of pictures in here this is where you would load them and I showed her and I had another video where I showed you how to actually do that so um we have some here that I already put in so for instance here's the media player one and here's Media Player Two so I have a beach scene here and I've got a weather here so let's go back to the switch now let's turn our key back on again okay well there I am now I'm going to say well I want media player one now in the background so that I'm at the beach sorry guys uh now you can't see this right now but I'm going to switch to Media Player 2 and say oh there I am so I got stood here and say well today's weather party cloudy and seasonable and I have 78. just a sidebar though if you do use Graphics I just got this offline I just got this online channel five and you can see up here it says first alerts so I recommend if you do get pictures from the news channels and you show it just mention them you know I'm sure they won't mind you know because but it is their picture so they have some copyright uh value to it so I usually say and today's weather brought to you by wpbd Channel 5 First Alert weather and today's weather is blah blah blah anyway so uh you say well okay now I want to change the picture so I want to put remember I had the beach here and I had weather here well there's another option I have and I I have a little rolly video here now I have that but that's pretty cool so now I'm star gazing so one day at the beach and the next thing you know it's night time pretty cool so let's go back to the beach now let's go back I'm going to turn my my key off I'm going to go back to our software controller back down to Media so you know I want to change that background I want to put something else in the back row so here's where they you know I have different pictures there's like the library here's a Sports picture so I just changed them there now when I go back to the switch and I go back to my key say no I want I want to I changed it to oh I'm in the library now uh I've come back from the beach I got a little tan so I'm in the library so that's pretty cool let's go back here's our stargaze so now what happens a couple times I've noticed that the let's say the lighting changes or something like that and now you come in the next day and you're like oh I'm fuzzy again I don't know what happened uh uh I got all fuzzy well a couple things could happen the lighting could change maybe there's another Shadow it's a different person so this is this is how you correct it you go back to the let's see let's pull this back up again remember you go back to the panel and let me turn my key off and you're going to go over here and make your little adjustment okay so now let's go back in and put the key back on so you can see what you're doing and then I'm going to go over my key and I'm going to move it again and see it moved but I got rid of the fuzzies so much better right so now you can do your backgrounds change them video and that's the simple way to do it there's a lot more to other and then there are other keys that you can do also but after another video so ah keep stargazing thanks for watching and uh I think you'll realize that it's really not that complicated once you get into it and and I do recommend that you have a student on the uh software control and when we're setting up at your school you're actually having a separate computer that does that then you've got the switch over here so let's go back to the switch I want to show you something too on a switch up here there is a button for key one so if I put that on I could you could key with the button and then change the background with your with your software so let's go back here where was I yeah that's it so if I turn that off oh well what you can see that there's where the button is to that so may seem a little they seem a little what do you say but once you do it a couple times you'll get it I'm sure you will okay well enjoy your TV studios and enjoy your students excitement when they are able to play and do different things so thanks for tuning in and we'll see you again on our next one [Music]
