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.
#Adobe after effects cc 2018 how to create a light wrap 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.
