Join Lee Lanier for an in-depth discussion in this video Finishing tracking the foreground elements, part of VFX Techniques: Building Replacement with After Effects.
So far we've tracked two static elements in the foreground using the tracking data.…If I zoom in we can see that those are this Lamppost, and also this cluster of…cars here, you can see them right here, if you turn on the mask Lamppost and Cars.…There is one more thing we can cut out and track that is going be useful…and that's this streetlight right here, this tree right here, and part of this lamppost.…The reason is those elements cover up this building, and once again, we're going…to replace that building, so it would be great to have those in front of the new…matte painting building.…
We can use the same process though. I can grab a copy of this frame_119 of the…street, drag it down to the Composition.…I'll rename this Light and then cut it out.…I'm going to go to the very last frame of the timeline here and once again use my…Pen tool to cut this out.…I am interested in this streetlight right here with its pole, have to zoom in…pretty close to see it, up the pole here, across the pole, and a little bit of this tree.…
Learn how to track the footage with the Adobe After Effects 3D Camera Tracker, replace areas such as the sky, rotoscope moving elements such as buildings and cars, and integrate a digital matte painting so it gains appropriate shifts in perspective and scale. You'll also apply color-grading techniques and learn how to fabricate reflections. The course also covers an alternative motion-tracking workflow with the Foundry CameraTracker plugin.
