Hey guys, this is E. Meek 77 for finalcutvideosschool.com.

Back at you with another Shake tip; I've got a question from a feller who wanted to know in shake, how would you go about removing something from an object?

So you want to remove a sign, or somebody that’s in your scene that shouldn’t be there. I'm going to use this composition, this picture here to comp a camp. I want to put a barbeque in a tent and some people. And this sign is in a way, and I might even want to remove this people too so would I go about doing this without a clean plate, and stuff, there are so many ways to do this.

So let me show you the cheapest way to do it, by using your mask input here. I don’t like to use the mask input very much. Only for certain things, they’re very good for you and they are useful, but I don’t love to use them a lot if I don’t have to I like to use switch mask and inside and outside and key mixes because I like to see all the nodes in my tree and exactly everything that’s going on. And when I have a rotoshape or something going into the mask input, it’s kinda hard to tell what’s going on.

So I just like to see everything laid out in front of me and see all of my aspects just like you have the capability of inverting your rotoshape from within your node, if you wanted too. But to me, I would just add an invert node, because I like to see all of my processes laid out in front of me. So now, let’s get back to this.

I went to my picture here, and I have appended a move 2D node. Let me get rid of this one and just do it all from scratch. Okay? So we’re going to transform and appended move 2D. now, I have this move 2D node.

Now, I'm going to take my rotoshape that I drew around my sign or around my people which ever what I wanted to do. And all I got to do is take it and pop it down into my mask input of my move 2D node.

Now, if I go over to my move 2D node, and move it, watch me slip this sign out the picture.

Now, what want to do is go to rotoshape, filter, and add a blur to this and blur it maybe 10-15 pixels, and get rid of that edge. And now, as you can see our sign is done. But I don’t like to do it this way so let me show you how we do it in the real world.

So let’s take or sign and we’re going to append the move 2D like always, transform, and move 2D. Then I'm going to click my original footage and I'm going to branch a key mix go to layer. Key mix branch. This branch is the key mix off.

So now, I'm going to take my move 2D and put it in the middle node, my middle input of my key mix. Then I'm going to take my roto shape, and put it in the last, input off my key mix.

So now, we have this little tree built here. I'm go into my move 2D parameters, and move it, and as you can see, it slips it right out of the scene. And this is the correct way to do it. And see we just taking that rotoshape straight down into your mask of the move 2D, do it this way, because this is going to be more flexible. It’s going to tell what you’re doing better, and I just, this is just the better way to do it.

As you can see the sign is gone. Let’s go over this picture here, and see if you can do the same thing to these people. So, let’s go to transform, move 2D, now we have our move 2D node. Let’s go back up and select our picture again, layer, right click key mix, and branch to key mix off. Bring the move 2D down to the middle of your key mix. And now, we’re going to draw a shape. So let’s go to image, select our rotoshape. We will work in context, lower the picture into the viewer and the parameters of rotoshape down here. And I'm going to go in here and click right around this feller here. You know, if you want to be more accurate in this, you don’t have be this tight on the shape either it all depends on your scene, what you’re going for, because I'm not sure how this will look because I've never done this before to this feller I'm not sure have the edges were going to be because this is kind of on the fly. So now, I have this shape, I'm going to plug my rotoshape that I just made into the key mix, last input in my key mix.

Now, when I move him he’ll slip right out the picture; now see how things are messing up there. We’re going to have to do some work here. Adjust to some work to our rotoshape. So it’s slipping out there and I’ll go and slick my rotoshape a little bit. Then this brings in a tad, as his showing.

Now, I'm going to adjust my edges just like my edge and I want to go in and just adjust this edges a little bit to kinda make it a little bit blur on its softness. This is one of the handiest tricks you’ll ever learn in shake, how to remove stuff from an image without really having a clean plate.

So now, let’s see what that looks like without, we may have to add a blur to our rotoshape and it looks like we’re going to have to add little blur just to make it a little more believable.

So we’ll go in and write us a blur there, and then we’ll blur it. Okay! Now you can go in and fiddle with your rotoshape you know just to try to make it as believable as you can. And as you can see for a real fast job, it’s not bad. I mean of course when you go in there, fiddle with your blurs and your fades and all this good stuff and you could make it look really, really, really good.

You can remove this tree; you can remove anything you want. So, that basically is how you do it guys. You key mix, with the move 2D with your rotoshape and when you move your key your move 2D. You can slip that sign or person or whatever you want right out the image guys.

I hope you’ve learned something on this I really do. I'm sure you will be using this trick a whole lot the more you get in to this and I hope you do, I hope you’ve got something it from it guys. We’ll see you next time.
