Welcome to this brand new section of the after effects course in this section we're going over a new tool called rotoscoping and after effects in the latest cc versions has really updated this tool to make it easily to separate different aspects of a screen, including parts of a screen even when it's moving, this is a sample shot and I'll play through this from a commercial that I helped work on for a local business. And what I was able to do was segment out and solo this cup of, it's like a fresh squeezed juice and that has color and then the background we separated it so it was dispatched aerated and then we were actually able to separate the boy here, which we added color to first and then we brought up color in the background and so there's lots of different things you can do with rotoscoping, you could do something like this or you can take out an element from your screen completely and put it in another video. It's another way of doing some sort of like green screen work. So we h...

ave the project file for you to work on. So go ahead into your computer after effects folder and find this rotoscoping dot M O V file, import that into after effects and then just drag it into a new composition. Go up to the roto brush tool up here then to actually start using this tool, you'll need to double click this composition window. What happens is you open up the layer window which is when you're dealing with the roto scope tool and some other tools like tracking you actually go into the individual layer within the composition and you have them in panels right here. So when you're looking at the layer panel up here, you're just looking at this individual layer up here. Now you'll notice that my mouse is this green little circle and this is where we can make selections. So what you want to do is drag around the edges of whatever you want to select. So first let's actually segment out this boy and then we'll segment out the cup later on. So to make a selection you just click and drag and typically I'll just drag around the edge of my selection. It doesn't have to be perfect because after effects is pretty smart at making a selection based off of the edge of things and we can make adjustments afterwards too. So once you'll see that I'm dragging and unclipped, what happens is you get this pink line surrounding our boy but you see also that there have been some selections that I don't want. Like this little bit right here in the bottom left. So let me actually make this panel a little bit bigger so we can see a little bit more. And you'll also notice. Take note that my timeline indicator is at the very beginning of my project or my composition. So to de select anything just press the option key or alter if you're on a pc to get sort of an eraser roto scope tool and then just click within any area where you don't want to make that selection. So just like so when I did that a little bit more of his shirt that I do want got deleted. So let me go back here with my green tool. When I stop pressing the option key, I get my green tool back and that looks pretty good. So here's the thing we've made this selection but this is the selection just for this frame of the video. When I move forward in the video say I just take my timeline indicator, move it up here. What happens is we don't get anything as our selection. If we go a little bit forward after effects tries to do a decent job and here it actually did a good job and it continued to make this selection but sometimes it doesn't make the perfect selection. So you have to go frame by frame literally and edit your selection and we'll get to that. It'll be a little bit more difficult when we're soloing out this cup down here to go frame by frame. What I'll do with rotoscoping is put my time indicator at the very first frame and then go literally one frame at a time by pressing command right arrow. So that would be control right arrow for pC users and as I do that I can pay attention to what this selection is doing and making sure that it's selecting everything I want and you want to make sure that from the beginning it's perfect because if you make a mistake and later on you realize, oh his I wasn't selected or something crazy like that. If you make that selection at that point it only affects from that point forward. It won't select all affect all of the frames before that. So what I noticed right here quickly is that his arm right here? His shirt doesn't have a little selection and I noticed that up here around this fifth or sixth frame. So I actually have to go back to the very beginning, make sure his shirt is selected properly. Like so and then go forward. So now I'm just control or command right arrow and literally I would just go through this one frame at a time. This is a little bit tedious but I would go one frame at a time. Another thing you'll notice is this little timeline here in our layer window right now and then there's this little bar down here which is the roto brush and refine edge span. What this is is After effects automatically trying to figure out what to select in this time frame but it only picked the 1st 17 frames. So to extend this for the whole clip, I'm just going to take this little part right here where you can see there's little arrows to the right and then it stops and then it's just this black bar, click that and drag it all the way to the right And now, after Effects is automatically going to try to make this selection for me when I undo this. Let me show you at this point in time. It makes that selection. But on the next frame it doesn't have a selection. So I want to make sure I extend that all the way. So after Effects knows to automatically try to make that selection. So literally just going through all the frames. So what do we do with this now? If we go back to our composition, you'll see that our boy has been selected from the background and you'll see that there's some menu options in the effects controls panel to adjust how this selection works. And that's what we're going to be covering in the next lesson. To make sure this looks as clean as possible.
