And your scale number may be slightly different than mine, so just try and visually match it. Now, the text is very large, so I'll press S to open up the Scale. And we'll set -27.0 for that and press Enter to set.
So, press A to open the Anchor point and usually I would scrub on these parameters as I reposition, but I already know exactly where I want things to go. In order to reposition this, I'm not going to change the position, I'm going to change the anchor point. Click and drag on the Z Rotation parameter until you get to a setting of 91 degrees.
Let's press R to open up the Rotation and Orientation settings. Click once on the Font drop-down menu and rather than previewing fonts, let's type Arial, arial, press Enter to set the new font. Now, let's go to the Character panel on the right and change our typeface. Then type 05 and grab the Selection tool to set the type. To edit the text, go to the Timeline and double click on the T icon for the Text layer. And this time, I want you to choose Create Text and Camera. Once it's set, move your mouse back over the center of the target and then right click or Control click again. So, it's really important to go ahead and set that. So, whenever you insert something with the 3D tracking data, it will automatically be inserted at the origin. And then choose Set Ground Plane and Origin. Once you have it in a location you like, right click or Control click if you're on the Mac, right over the center of that target. Once you see the Move tool, go ahead and drag the target anywhere you like in the scene where you'd like to place your graphics. And you should notice the mouse change into the Move tool here. Hover your mouse over the middle of the target. Now, it's not that important that you have the exact same points that I do, I just want you to make sure that the target looks like it's actually sitting on the tarmac. If you hold down Shift and click on other points, you can use those to further refine exactly where the elements are placed in the scene. And so, if I click, those three points will be selected. If you notice, as I'm moving my mouse around the scene, I'm getting three points that create a triangle. So, I'm going to hover around this general area and I want my target to look like it's actually sitting on the tarmac. And when I'm out here, there's far less distortion. Now, when I hover with my target, it still got a little distortion, you know close up here, but it's nowhere near what it was before.
Notice it doesn't have to reanalyze anything. So, I'll specify my Horizontal Angle of View and set it at 73.0 degrees and press Enter. And it just so happens the angle of view, or the field of view, for my specific camera was 73 degrees. So, I went online and searched angle of view with my model of camera that shot this footage. But when you notice some drastic distortion like we saw with the target, you may want to go in and specify the angle of view. That means the lens wasn't zooming in and out during the shot, which is correct. If we go to the top of the Effect Controls panel, under Shot Type, Fixed Angle of View has been chosen. Now, I'm looking at this, and the target is very distorted. And the target determines where you're going to place something in the scene. Now, if you hover your mouse over these crosses, you'll notice there is a target that appears. Once it's finished, the effect will be highlighted here in the Effect Controls panel, and you'll see these crosses in the runway here.
#KEYLIGHT 1.2 WHITE BACKGROUND UPDATE#
If you want to get an update to the status, go ahead and look in the top of the Effect Controls panel under the 3D Camera Tracker, and you'll get a real-time update unless it's finished. This allows you to work in any other composition in After Effects while the analysis is still happening. Immediately, After Effects will start analyzing the footage in the background. So, to start that process, let's select the (Runway.mov) layer in the Timeline, then go up to the Animation menu and choose Track Camera. And I want to add the number 05 to the runway right in this area here. The footage in this project is of an airport runway. We're going to use that effect to place some text into a scene, making it appear as though it's been sitting in the environment of the scene itself. The 3D Camera Tracker effect can analyze a piece of video and determine the exact placement and movement of the original camera used to shoot the footage.
