7.3 Camera Tracking in After Effects

In this lesson, you're gonna learn the basics of camera tracking. Follow along with this lesson, make sure to open up the camera tracking.aep file and you're also going to need this HYPERLAPSE LOUVRE.mov file, and you can find that elements. All right, to start, I'm gonna create a new composition with my footage here. Just gonna drop it onto the new comp button. And then I'm gonna come over to the tracker panel and I'm going to hit track camera. Now that's going to put a 3D camera tracker effect on this layer and it's gonna get to work analyzing this footage. Now you can do other things as it's analyzing the footage and as it's working out this track, we can jump to another composition and work or do whatever you like but this is gonna take just a little bit to figure out. All right, that has finished. And what is happened is, after effects analyses the video sequence and extracts the camera motion and the 3D scene data and what this allows us to do is composite 3D elements over your 2D footage. In addition to adding 2D elements to the 3D environment. So if you click on the Camera Tracker and you scrub in the timeline here, you will see that there are hundreds of trackers that have been applied to the footage, and for the most part, these are locked to the part of the footage of this is suppose to be locked too. So for example, there's a bunch of trackers on this building, and as you scrub along, those trackers don't move around or dance around a whole lot. And so, I have a pretty good confidence that this track is going to work. Now, sometimes when you use the camera tracker, you're tracking things that have some foreground objects, maybe people walking by or whatever that are obscuring some of the geometry of the scene, buildings and other things in the shot that after effects would use to try and figure out the 3D data. Basically, what is the geometry that the after effects is looking for and then how can it extrapolate a camera from that? And if you have things going in front of your shot, that can really mess with the 3D camera tracker and you won't get a very good track. It'll be all over the place. So sometimes what you need to do is to mask those things out. And then use the camera tracker on that pre-comp with those foreground objects removed. You can find more information about that online but for now, I think this is a pretty decent camera track. The only thing that's going to be a little tricky is this pyramid here and that's because it's made of glass and there's this outer structure here, just gonna click away from 3D camera tracker. This is outer skeleton and then below that, there's an inner trust system, kind of all through here. And so, if you look at the trackers, some of them are gonna be locked to the outer skeleton, and then some of them will be locked to the inner skeleton. So trying to get something to stick on this particular object, like if I wanted to get something to stick right on the outside of this and be locked to the perspective, that would be a little tricky. Not impossible but outside the scope of this lesson. So I'm not gonna do that. But what I am gonna do is show you how to make text look like it's hovering directly above this pyramid. And so to do that, I need to do two things. One, I need to create a camera. And two, I need to insert some text. I can do that all in one shot here. If I scrub along the timeline and I find somewhere that has a decent amount of trackingpoints at the very top. And the reason why this is going to work is because the distance between these trackingpoints is relatively minimal. So if you click here, it will create a selection between three tracking points. If you wanna select more, which is sometimes beneficial for getting a better track, you can just draw a selection around multiple tracking points, and if you right click here, you'll see that all the options are create something and camera, that's because camera has not been created yet, even though it is solved for the camera, there hasn't been one created. You could do one over here, separately, just click create camera, and now when you click on this, it'll just say create the object. So you can create text, you can create a solid, a null, a shadow catcher and the light. What I want to do it create text. All right. It has just created my text. Let's preview this and see what it looks like. And I'm just going to zoom out to 50% here. Okay. That's not too bad. My text here has the anchor point in the center, if you're following along. You can change that with the align tools here in the paragraph panel. So what I'm seeing right now is it looks like it's tracking pretty well. The orientation isn't great. And so, what I'll do for this particular shot is I'll pick a section where the front of this is pretty flat and then try and line up the rotation of my text to that. So by text layer selected, just press R, that will bring up the rotation and then I can adjust the orientation to try and get it a little bit better looking. In fact, I'll just zero some of these out, see what that looks like, okay, it looks like that is actually a lot closer and then I'll just rotate it like this And then scale it down, put some different text in here. That makes more sense, and then I will reposition this but I'm only going to move it up. I think that's okay. Actually it looks like it's in front, so I'm just gonna push it back in z space here. And I'll just play this and see what it looks like. So that actually looks pretty decent. It's kind of a slow playback there. But it looks like that's pretty locked to the pyramid. It's looking pretty good. So using this technique, you can add all kinds of things to your scene, including 3D objects. And with the after-effects lighting system and some other wizardry, you can composite computer-generated 3D objects into your shot and make them look like they were actually there. In this particular case, we just added some text, it's locked in 3D space but it doesn't really look like it was there because it doesn't have the same lighting, and it doesn't really have any dimensionality to it. That's something that you can learn coming up in the next lesson, where I'll show you how to create some native 3D texts for this. So check that out, coming up next.
