Join Mark Christiansen for an in-depth discussion in this video Solve and adjust with Camera Tracker, part of After Effects Compositing: 6 Tracking and Stabilization.
- Now look at this scene,…which when we shot it was intended…to be a planar track using mocha AE,…but turned out to work a lot more cleanly…using Camera Tracker.…The reason for this is probably that our subject…travels right across the area that we're tracking.…And that is a big challenge in mocha AE…but really no challenge at all for Camera Tracker.…The reason for that is that he's only occupying…a small percentage of the frame.…
So let's give it a whirl.…I'll let Camera Tracker do its automated work…analyzing the scene.…As you know there's nothing really to do at this stage…except wait for the analysis to take place.…And within a few seconds we'll have…a number of track points.…Once the camera's solved.…Now once I have a solution,…there are a couple of things I look at.…
One if just how well do the points appear to be sticking?…And to back that up, I can twirl down Advanced,…and take a look at the average error.…Now here, it's at .90 pixels,…anything below 1.0 is a very good average error.…So this seems to be quite a good track,…
Here, Mark Christiansen shows how to use the five different After Effects trackers, customizing them to work best in the situations that motion graphics artists encounter most often. He covers the fundamentals, as well as opportunities to think outside the box, especially when an automated approach won't work.
