Join Lee Lanier for an in-depth discussion in this video Tracking additional foreground elements, part of VFX Techniques: Building Replacement with After Effects.
We have used the tracking data one more time to track a static element in the…foreground, in that case it was the lamp pole right here, this will allow us to…put a new building behind that at a later step.…We can continue that process by cutting out these cars here, these three cars…also cover up the building, it can potentially be a problem when it comes time to…put the new building in.…So we can use a similar technique. We can take a static frame, cut it out, and then…use the tracking data. Let's do that.…I'm going to grab Street_119 once again, which I brought in previously,…drop it into the comp above the Lamp, I'll rename that Cars, just so I know what that is.…
Then turn off the street, and then zoom in, and then use the Mask tools to cut…this out. Let's grab the Pen tool, zoom in, and try to cut these three cars out.…I'm going to do this fairly quickly, so you can spend more time to do this more…accurately. I don't want the background I just want the cars and in this case this…truck, or SUV, this white car, and this other truck or SUV. Try to get all the detail,…
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.
