Hey guys, this is Eric back at you with a little Shake tutorial.
In this tutorial, I was asked how would somebody go bout removing tracking markers. I want to show you a simple easy way to go about removing tracking markers, because if you key this out, this is going to be completely in the way and we can roto her out if you want to in another video, I could go through, and show you how to go about rotoeing her out but we’re going to remove this tracking maker so we can key that. And we’re going to concentrate on removing this tracking marker right here. And then I’m going to show you how to remove this tracking marker I might not go all the way through it, but I’ll show you how to do it and then maybe in another video we’ll finish the shot up and key it and stuff like that.
But in this video, we’re going to concentrate on removing this tracking marker, the track here, a tracker and this tracking marker being a quick paint. So, let’s go ahead and add a tracker for the transform tab, and this, in the tracker here, let’s take our tracker and put it up here. So let’s zoom in, and see what we’ve got.
Bring our search area so, let’s frame back out. Now, we can go through and do this by hand because its not very many frames, it wouldn’t be hard. So let me start the track here. And that stuck pretty good, just track back the other way. Now it’s going off screen but that’s okay, because it’s such very few frames that’s not going to be hard to fix, so we zoom in up here. And let’s go back through here, and see where we went off. That’s good enough. I don’t have to be very accurate but we’re just going to remove the tracking marker, but we want to get the one to work it off a big time. Like right there. It’s all out of there. So, I'm going to go and adjust this back up.
So, okay, looks like we got to track for it. It’s not too bad. So now, that we got this rough tracker, as you can see we just run through it once and there is him really adjusted any. So that’s good enough for what I'm doing here in YouTube.
Okay let’s frame back up. Now, we got this tracker, let’s go in and create a rotoshape. First, my video is 720x480 and I'm going to my globals, and make sure it’s 720x480. So I want my rotoshape to be the same size.
So let’s go to our image tab and create a rotoshape. Let’s look on our original picture and let’s draw a square, a box, around our tracking marker.
Now, as you can see, I have this little square here. I'm going to pin the mult node because I want to colorize it, okay, we want to go back to my original image just like my mult node color swatch and select the green, of the green screen.
Now, as you can see, my rotoshape is the same color as my green screen. Now, all I have to do is add a layer node over to my tracker, lay this rotoshape over top. Now, as you can see, we have that covered up, just add a blur to our rotoshape, and blur it a little.
And like so that helps out a whole lot so now, let’s go select our rotoshape, right click in the center. Attach tracker to shape, tracker to track one. That’s my minus tracker two as you can see, yours are probably tracker one or whatever it is. And there, it should be attached. Now as you see, when I move back and forth, this rotoshape that I have here moves right along and covers that track up if I go back to just the rotoshape. You can se it moving so, let’s cut that tracker attached to it.
So now, when we frame back out, our little track point is gone. Now let’s just do a couple of frames with the quick paint so I can show you how we would go about doing that. Let’s find a good frame here and it’s going to be a good spot to paint this out. I don’t know it looks like a pretty tough spot right there so just paint right there.
So, let’s go back up to our very top here, and I guess you can add it down here too, if you wanted to, but I'm just going to do it to the original, let’s add a quick paint. You mean the tab quick paint.
Now, I'm going to select my clone tool, and I'm going to go in here, and clone out this little tab as you can see., So, it’s just a little bit far, bring this one like this. So look it down, because we want to make sure we get a good cloning here. We don’t want to half way do it? As we do it right if you’re going to do it. Sometimes it takes a little bit of work because you’re right in here so close to the hair, that you just going to feel it with it, and take your time and I don’t want to paint out that hair out there, as you can see.
So, what I'm going to do is when I go in here to shrink this down, and go right over the top of this hair here that’s close as we can. We bring that back out.
Okay, may we have that tracking marker removed for that frame and if we go down here, both tracking markers are removed now. All you have to do is just go frame by frame and paint it out frame by frame. Now if it’s two main frames for you to do that we would just go about, go about rotoing her out and there are several methods we could use to roto her out and we’ll go through that in a different tutorial, because sometimes, it’s just two main frames that paint out a tracking marker. But luckily with this footage, it’s just about a hundred frames long, and it’s not a problem. Usually for YouTube and stuff it wouldn’t be a problem but for something you are getting paid for instead if you want to look into rotoscoping.
So now, we have this, let’s go ahead and key it out real fast with a key lot. Now, we have this is going to our original footage, and we’ll apply instead of a blur color space—instead of a color space—blur a color space, and I'm just going to add a UV blur from physics, because we’re going to blur out edges. And yes, we can do this blur out the edges here, by using the nodes supplied in Shake. And I have a video going off there. It is called Smooth Jagged Edges, I think it’s in my Shake’s play list, but I'm just using this one physics plug in UV blur just to save time.
So now, let’s go ahead real quick and let’s just find a background. I like to use about the over node, but let’s prop it in to the key lot, just for simplicity’s sake, and there we go.
As you can see, our tracking markers are gone, and we have a pretty good key.
Now, let me jump up for frame and show you what it would look like to remove those tracking markers. There it is, but we have the tracked shape. Track the rotoshape with this tracking marker up here, and we click painted this one out and we’ve ended up with a pretty good key.
So I hope you guys have learned something, and we’ll see you next time.
