VFX Techniques introduces common yet critical visual effects techniques that are used in film and television shows on a regular basis. This installment shows how to build complex composites with Adobe After Effects and mocha, where motion graphics are mapped to live-action footage of an actor. Author Lee Lanier starts by combining rotoscoping and effects to digitally apply makeup to an actor to disguise motion tracking marks. Then discover how to transfer footage into mocha and generate planar tracking data that you can use to motion track graphics to the moving face of the actor. Plus, learn how to build and adjust motion graphics to create the look of a virtual tattoo and a pair of holographic heads-up glasses.
We've finished all the visual effects work on this shot, so now we're ready to render. Let's take a look at the shot first. (video playing) So, we have our color grading, we have our heads-up display, our Armature, and our Tattoo tracked in. So, to render out, I simply need to add this composition and color grade to the render queue. Composition > Add to Render Queue. That gives me the Render Queue tab.
It's also listed down here. I need to change my Output Module and my Output to, and then I can render. So, in terms of Output Module, I'll click the word Lossless, and the Output Module Settings window opens. In terms of the format, I can choose a movie just for a test. If I wanted to render out something with a higher quality, I would choose Image Sequence. But for now, I'm just going to choose a QuickTime movie, QuickTime. Now, whenever you do pick a movie, you should change the Format Options to maximize your quality.
Click this button. There are a number of choices. All the different Video Codecs are up here. I'm going to select MPEG-4. Now, there are several other ones that are good quality too like, H.264, but this will do for now, MPEG-4. Click OK. This is all good. Click OK. And then go and pick a place to render this, and also a name for the movie. I'm going to go to my desktop and just call this one Test. Save that.
Once these two items are set, I can render. Once the render finishes, the yellow bar will disappear and you'll have a movie on disc where you chose to write it out. You can open that movie outside the After Effects. Now, I want to just import it just to check it. File > Import > File, go to my desktop, and grab that Test.mov. I'm going to open it up here, just in the footage viewer and take a look.
And there we go, the final rendered movie. The project is now complete.
