Join Mark Christiansen for an in-depth discussion in this video Apply a 3D track, part of After Effects Compositing: 6 Tracking and Stabilization.
- So all we've really done at this point…is get this 2D layer, a big green square,…to match the motion of the wall.…So the shot is not done until we…swap in some other piece of artwork.…So let's add this rainbow that arches across the frame,…right now in 2D, to the motion of the scene.…Obviously the first thing to do is…make this 2D layer a 3D layer.…And that brings you to the scene…but at the wrong position, it's kind of…bouncing around over here on the left side…of frame somewhere near our camera.…
There's a quick way to fix that in any scene…when you have a reference solid like this,…I don't need to even see the solid but I'll…leave it on for one more moment.…And hold down the option key while I pick whip…from the rainbow layer to that solid layer.…So now, the two layers have the…exact same transform data,…so specifically, orientation matches,…which means they both align to the back wall.…You can see though that the rainbow numbers…are all zero so I'm going to actually turn off parenting,…this time without holding down option or alt,…
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.
