Also, once you’ve tracked your shot, you can check in the stats section of the effect to see the average pixel reprojection error (i.e., you can tell how many pixels off your track could potentially be). Usually though, the track will be more or less spot on. The only real caveat to the 3D camera tracker is that when you’re unable to get a good track, you have to finagle it a bit. Just select your footage, and click the “track camera” button in the tracker panel.Īfter it’s had some time to think, you’ll be able to select tracking markers (usually points of contrast that the tracker was able to position through time) to which you can add solids, cameras, text objects, and more - these objects will now inherit all the motion of your shot. If the shot is moving, you’ll need a rock solid track in order to keep all of your composited elements moving along with your shot.Īfter Effects has a great 3D camera tracker that will allow you to do everything you need, and best of all, it’s extremely easy to use. Motion tracking is one of the core aspects of compositing.
Whether you’re adding some floating dust particles or slowly moving smoke or fog to your scene, you’ll need to master a few techniques to get it looking right. However complex you want to get with compositing, there are some things you’ll find yourself doing over and over that you’ll want get used to. Sometimes, compositing is just adding a bit more detail to a dull sky through a “sky replacement” - or even replacing the blank screen on a phone with the app you’re trying to advertise. Compositing doesn’t have to be complex, CGI-based visual effects with 500 layers.
