Join Lee Lanier for an in-depth discussion in this video Adding a core rotoscope, part of VFX Techniques: Building Replacement with After Effects.
We have added a new sky to this street, so we started to build the scene. That's great.…However there's still a few problems if I zoom in here, you can see that the keyer,…the color range tool, has left holes in some of parts of the buildings, like down…here where the billboard is, some of these windows, also further down in the street,…that's not good, I need to fill that in somehow.…I don't want to change my keyer it's working for the most part, so one trick in…this situation is to add a core roto, what that means is to add a new copy of the…Street, rotoscope the sections in question, like where the holes are, and basically…add that back on top of the composition stack, let's give that a try.…
I'm going to pull a new copy of street down to the top of this comp and now obviously the…entire frame is restored.…Now I can zoom in and using my Pen Tool draw a mask that fills in the problem areas.…So Pen Tool, I will make a very rough mask in this area where there are holes opening up.…Now as I do this I don't have to go to the edge of the buildings.

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.
