Join Lee Lanier for an in-depth discussion in this video Employing multiple keyers, part of VFX Techniques: Crowd Replication with After Effects.
We've gotten 2A and 2B set up and those are working in terms of green screen and Motion…Tracking, we're now ready to finish up the second row with 2C, but 2C has some other…issues but we will talk about those right now.…Let's import it first, back to the Footage folder and 2C, drop this on top, turn off…the Caps Lock, and there it is.…Now one problem is this little piece of blue tape.…
Unfortunately the actor's arms crossed that, so in order to get rid of that, we could use…the rotoscope which takes a lot of work, or we could try to key it out.…Now if we key that blue out, we might not be able to get the green, so we might treat…that area separately, in fact we'll save time if we do that.…So what we can do first is isolate that area to pull that blue out of it.…I'm just going to draw a Mask over that problem area, and I am going to turn off other parts…I don't need like the background, I'll turn on the Test Background, though, so I can see…the red, I don't need the other crowds, I'll turn those off, there we go.…
