Join Alan Demafiles for an in-depth discussion in this video Create a track matte, part of After Effects CC 2018: VFX Essential Training.
- [Narrator] After Effects allows you to reference…another layer's transparency or pixel brightness…to control what is visible.…A layer that controls another layer's visibility in this way…is called a track matte, and we'll examine some of that…here in this movie.…So here, in this example, I've got a text layer…that has its own built-in transparency.…Everything inside the letters is opaque.…Everything outside is transparent.…On top of that I have a gradient,…which has transparency as well.…If I scale this down you see that…everything outside the box is transparent.…
Everything inside is opaque.…So we can use this information to…create what's called a track matte.…Track mattes work in pairs.…The layer that's going to be doing the…borrowing of information, the borrowing of…transparency or pixel brightness information…is on the bottom, and the layer that is…providing that information is on top,…and that's the track matte.…So if you don't already have it enabled,…go ahead and click on this button here,…and that will toggle the track matte column,…
