Join Alan Demafiles for an in-depth discussion in this video Isolate elements with different mattes, part of After Effects CC 2018: VFX Essential Training.
- [Instructor] As we've seen so far in this chapter,…there's more than one way to create layer transparency…for using compositing.…Here, we will use the shot that we previously tackled…with the Roto Brush tool…and instead we'll use another method…to achieve the same result by using a difference matte.…With difference mattes,…we tell After Effects to look at one layer…and compare it with another.…Any place that's different will create transparency.…So here in our shot, we have the same result,…but this time in this foreground layer,…layers two and three,…we're deriving transparency by a difference matte.…
So how do we use this?…Let's start with this composition where it's a clean start…and layer five is our clean background plate.…We're adding in our fire layers…and of course we need to bring back the guy…in our foreground so let's duplicate layer five,…we'll rename this foreground, FG,…and put it just underneath the letterbox there.…So now that we're starting from scratch,…we need to talk about how we can use this difference matte…
