Final Cut X Green Screen Keying Tutorial - Zach King

hey guys what's that my name is Zach king from the Final Cut King YouTube channel my website is fine okay King calm and on behalf of to tape I'm gonna be going appropriately enough over a topic called chromakey also known as green screening and so we're gonna jump into Final Cut 10 here and get started you can download the footage to follow along the link is in the description and have fun with that and just go with me here so if you're ready to jump in I'm ready let's have some fun I just have a tube tape cloth draped over the background I've got some creases in the cloth you can see and also just one light on there nothing super fancy but this is all to show you that Final Cut 10 is pretty powerful when it comes to chroma key and it's very simple so let's get started by dragging this down to the story line and we're gonna begin keying now you need to come over here to your filters tab and we have a folder called King we're gonna drag this key right on top of our clip and you can see it did some initial pass King but we need to select our layer this is where all our video parameters for the keyer are held now we have to refine key buttons that we can use we have edges and sample color you can select which one you want to use and we're first going to use sample color and this just picks the areas that haven't been keyed out yet so you can do multiple sample colors here I'm gonna hit areas that don't seem to be king very well you also need to keep in mind that these need to be areas where your actors don't cross in front of just keep that tip so I've got four areas if you don't want one you can just select it and delete it and it turns out I didn't even need that one up there because this this one took care of it we're doing pretty good so far we've got our modes here we have three right now we're on composite we can also have a matte we can work from this is really good if you want to zoom in and you want to refine these edges and then we have the original to zoom in you just hit Z to get back out shift Z is a fit to window let's go back to our select tool so let's go to our mat and let me show you something all this black is gonna be the area than where we put our background so for example I'm gonna go to a texture here let's just drag in a curtain underneath if we go to the composite it'll show the curtain behind there well it works so far but I only have the green screen around this area the rest of the room needs to be cut out so we're gonna use a mat just delete that texture right now so you're gonna come back to your filters to king same folder and drag this mask onto the video layer as well now the mat has these four points we can adjust and it's as simple as dropping and dragging I told you that was pretty easy so now that we've got it all keyed out again make sure your actor in this case me I don't cross one of these lines if one of these crosses me or my hand goes out of frame and goes through the line it's gonna be a problem so right now it's hard to judge what we need to finish for the composite right now the edges might be a little choppy but we're gonna have to put our background that we're gonna be using in first before we know that so let me explain what I did for the shot the footage you downloaded has me on a green screen but it actually is the same background that I'm using as the background plate background plate is just a fancy term for saying what goes in the background of my shot here so I'm gonna drop that down now the reason I did this is so I can put text behind me or graphics without me having to mask out myself frame by frame so you saw me put that texture in there before so if I want I could put some sort of text behind me so what you have to love about green-screen is you can do a lot in post you click this button here and this is a transform so I can move my position I can scale myself up I can Center myself put myself off to the side there's so many options with green-screen let's go off and let's do a background and we can put me underwater so that's how you do green screen and final cut 10 do you need green screen material like the sheet I used bathroom - duct tape calm and if you want to ask me any more specific questions head on over to Final Cut King comm or my facebook page Facebook / the Final Cut King so I'll catch you guys in another video take care
