Learn about move tracking with Boris Match Move and Mocha Pro.
- [Instructor] We're going to move on to another important aspect of compositing, and that's match moving or motion tracking. Boris includes effects to carry that out; however, the current version of Adobe products, that workflow is a little unusual, so we're going to talk about that. So here I have a new project, partially completed, and this is 5.1 in the Chapter Five folder. This includes the jogger footage and also a standard text layer with the word power. What'd be great is to have that word follow the jogger so it's right in front of her face the entire time, perfect place for match moving.
Let's give that a try. I'll select the jogger layer, go to Effect, and go to the Boris Match Move. When I first apply it, there's a temporary foreground placeholder; so so far, so good. Now if I go to start tracking, there might be some issues. I'll expand the motion tracker rollout, and normally I'd go to track on the fly to activate internal tracking; and this would be similar to tracking with the standard After Effects tracker. When I turn that on, however, I get a error message.
Basically, this version of Boris cannot work with this version of After Effects because of some various programming issues. Now I still might want to use this Boris Match Mover because it has some nice properties for adjusting the track. But if I want to use it, what I have to do is this: turn off track on the fly, and then load the data from a different program. For example, I can use Mocha Pro to track and then export the data and bring it back here. Now Mocha Pro is different from the Mocha that comes with After Effects.
Mocha Pro is a standalone, and it has different licensing. Let's give it a try though; it's worth knowing. We're going to minimize After Effects and go to Mocha Pro. Now Mocha Pro has no idea what's going on with After Effects. They're different; they're not linked. So I need to start a new project here. So I'll press the new project button, go get my footage; and this is the jogger footage in the Chapter Five set of folders. I need to make sure it's the correct frame rates; 24, that's good. Click Okay. Now, since I've done this before, I have a temporary data file it wants me to overwrite.
That's fine. And here's the footage. Now I really only need to get a position off of her face as she jogs. I don't really need a shape or anything like that. Now despite that, I'm still going to create a shape and track her face; but then I can export it correctly. So let me zoom in first, and then I'm going to use my X-spline tool to define one half of her face. Above her eyebrow, over her ear, down to the base of her neck, across the chin; right mouse button click to finish that shape.
This should work pretty well despite the fact she goes in and out of shadow. It's going to track this entire pattern. Let's give it a try; I'm going to track forward. Now I need this to be somewhat accurate, but not perfect; I just need to get the position data from the center of that pattern. Now this is starting to slip off a little bit, so I'm going to wait until the very end and set a quick key frame to redefine the shape at the end.
Pull these points into the correct location, and then I could just leave it as is and let it interpolate on its own; but I think I'm going to track backwards to update the track, and it does a little bit better going backwards. All right, that seems good enough for this track. I'm ready to export. Now there's no link, like I said; After Effects has no idea what's going on here, so I'm going to export the data into a file. Before I do that though, I might want to save this file in case I need to return to it.
So I can do a file save project as, and I've already saved one for you to look at; and this is in the exercise files, Chapter Five Mocha Files, and there is a jogger track. If you want to take a look at my previous work, you can open it up. I'm not going to save this for now. I'm going to go directly to After Effects. So I'll minimize this, go back to After Effects, and now I can load that data. Now I do have to save it out to a text file. See I forgot; it's not automatic.
So I need to go back, click the export track (mumbles) button first; and here if I'm using Mocha Pro, I can pick one of these formats here. There's quite a few, but what I want is Boris effect center point. Select that text format, save that out as a text file. I can save it to my desktop like jogger.txt. Now, I've also saved you a copy so you can take a look at; so that's actually saved in the exercise files, Chapter Five under Mocha files, and there's the joggertrack.txt you can use yourself if you want to.
Okay, so I've already saved mine to the desktop. Now I'm going to go back into After Effects, and now I can load it. Click the load button under motion tracker, go to my desktop file; I just saved that a couple of seconds ago. Open that, and as soon as I do that, I get a brightly colored motion path and the temporary placeholder is moved onto the path. I want the word power to follow her, so I'm going to go down to the Match Move section and change the MM foreground property to the text.
Now I have two power words. I can actually hide the text layer because it's integrated the text into the original jogger layer. Let's play it back. So it's definitely following her, although it's stuck on her face. It'd be great to offset that and put it in front, also maybe give it some rotation so it looks like it's lined up with her in terms of perspective. There are properties for doing that right here in the effect. There's a transform section that determines various things like rotation.
Now the first thing I want to do though is probably go do the offset. There are offsets X and Y up here in the Motion Tracker section. So I'm going to offset this and push that word in front of her face. That looks pretty good. Now I do need to go back and rotate it, so I'll go back down to the transform rollout and try these various rotational properties like spin, tumble, and rotate.
All right, looks pretty good. While we're down here, I can also activate motion blur. There's a internal motion blur here. When I turn it on, it blurs the word based on how far it's moving over that one frame. Let's play it back. Before I do that, though, I want to hide this motion path. I go higher up, there is a show motion path check box. I'll turn that off, and we're ready to go. Play it back, and now it follows in front of her face and has roughly the correct perspective.
All right, so if you want to use the Boris Match Move effect with the current version of After Effects; you have to go to Mocha Pro, track there, export the data as the appropriate center text file, and then load it back in to After Effects. A little convoluted, but it works well; and the advantage of doing that is then you have access to these other properties that comes with the Boris effect.
VFX expert Lee Lanier begins by exploring shared Boris Continuum controls, and then shows how to apply stylistic effects. He explains how to work with the PixelChooser and Boris Lights, and discusses how to color grade and warp footage. He also takes you through using the Boris Chroma Key Studio and working with Mocha Pro for motion tracking, as well as how to add particles and work with 3D text.
