Hey guys this is Eric back with another Shake tutorial. I’m here to work with Lumakey a little bit more. This is jut really for one specific person; he wanted to know how to cut out an iPod and I don’t know what kind of footage of the iPod you’ve got, I don’t know if you can even do it this way, you might have to end up doing it domain your way and just RotoShape it out, tracking it to your footage but you can try a Lumakey and I want to show you how to use a Lumakey on this iPod picture here and you should be able to apply the same thing to your video.
So the first thing I’m going to do is apply Lumakey to my picture of my iPod. I’ll go to key, LumaKey, okay. Catch this in here, okay.Now I have this LumaKey attached. So what I’m going to do is hit my a key to show you my alpha channel and it will be black and white.
So now you go into your low Val and your high Val and start adjusting, trying to make everything that you want to keep in your picture or what and everything you want to get rid of black.
So you don’t wan to make your edged too hard, you know, you want a, it looks like a pretty LumaKey right there, so now what I want to do is I’m going to add attachment over node to this LumaKey. Go to layer, over then I’m going to find my background, I’ve got a picture of him; inside of an apple store here. I want to pop it into my other side of my over node, okay.
Now I’m still on my alpha channel, you won’t see much so I’m going to go back my view and hit the c key to bring the color back in. Now, there are nothings going on, why not? Well you’ve got to pre multiply. So go down into your over node and hit the pre multiply button, boom, no we have this great LumaKey but as you can see it’s keyed out everything white and we’re going to be taking of that and we can take care of that with a RotoShape.
So first let me try to add a light wrap to this so I’m going to select my LumaKey and I’m going to go to, I have a light wrap macro that I’m going to use, so you want to right click and branch. Look at my alpha and there’s my light wrap. Now if you don’t have a light wrap, plug in, I’m jus doing this for easy views, you can make your own light wrap which is no problem. If you need me to, I can make a separate video showing how to make alight wrap; light wrap from scratch and I can show you, I have videos showing how to make a blur from scratch because I use these at macros a lot; these plug ins that I’ve got just to save time but a lot of people don’t have them and if you dot me to make a video going thru showing you how to make a light wrap and a glow from scratch, then I’ll be more than happy to do that but for now I’m just going to us the light wrap that I got from high end 2D and we will go from there.
So now I have this light wrap, so I can go down in here to my controls now, foreground edge control and you can do your over all gain, as you can see, you can adjust how much the light wrap you’re actually going to have, okay. And there’s over all edge blur which will blur your edges, just want to that a little bit and there’s over all gain. You just have to go in here and it’s your brightness; you just have to go in here and adjust, you know, how predominant do you wan the brightness to black wrap to be on your key. And we got the over all blur, we can blur over all then we can go in and even have our background control but we’re not going to mess with that.
So I have this little generic light wrap here; we’re going to add into our scene here in a minute so let me go back to my over node and go back to my color. Now when you have this but we got to fill this is in and we’re going to do that with a RotoShape. So I’m going to go to image ands I’m going to select the RotoShape and I’m going to working context by loading up my over node and load in the parameters of my RotoShape in and I’m going to go in and make a box around an iPod like this. I can sure I get everything that’s not filled in, okay.
Now I’m going to look at my RotoShape Node, here’s what we got. So how are we going to get this inside of our key? Well no problem. I’m going to go to my LumaKey and I’m going to insert, let’s go to my layer. Now you can use an over, I’m just going to use in under because it helps me keep thing straight. This RotoShape is going under my iPod so I’m going to use an under, it just helps me keep things straight in my mind. Under and over is the same thing, just the input and output and reverse.
So I’m going to hit under and I’m going to take this under and I’m going to insert it between u LumaKey and my over like there right there. Then I’m going to take this RotoShape and plug it in right here to my second input of my under tab. No as you can see, that laid it on top of my iPodl; I don’t want that since it’s an under tab whenever it’s going to be on the bottom and this to be in the first input just like with an over tab whenever it’s going to be on the top, it need to be in the first input. So let me switch the inputs around like that right there. And now when I go back, you can see that the shape which is right here is; there’s other points for it is laid underneath my iPod. So I can, I can disconnect this and you can see that it’s gone and I connect back. Now all you have to do this track that RotoShape to your object, that’s all you’d have to do.
So now we want to add in out light wrap; let’s bring our light wrap down here. I want to click an over node to my light wrap and I’m going to plop my completed over node top to into this light wrap over node and that gives us a small tiny light wrap around and you can go in and adjust your light wrap. As you can see the more I bring it up, the more the light wrap surround it. We want a little light wrap, we don’t want a whole lot but we want it enough to where you can just, barely tell like there’s a little light ring, you know, and there’s a lot of attention that can be done on this video. I’m just trying to show you the basics.
Now if you wanted to, you could go in and you could add a gamma node if you want just to kind of make things look a little darker, let’s see what we can do with it here, let’s add a gamma when I bring that gamma node down it makes my hand and shadows a little bit darker.
Now we’d want to go in and clear up this edges; to clean up this edges and stuff but that’s basically how you pull a LumaKey on something and if you can’t get with the LumaKey on something and if you can't get it with the Lumakey man, you’re just going to have to RotoShape it out, track it by hand or use a tracker node, whatever it takes. Sometimes you just get footage that just can’t be helped; it’s just going to take some time. I’ve even had a RotoScope grass before, if you can imagine, yes grass, ladies and gentlemen so there are going to be times that it’s going to be necessary.
So I hope you’ve learned something. I hope you got something out of this and if you have any questions, get a hold of me, be more than happy to answer them and this is Eric from Final Cut Studio School saying, ‘we’ll see you next time.
