Join Alan Demafiles for an in-depth discussion in this video Use track mattes, part of After Effects CC 2018 Essential Training: Motion Graphics.
- [Instructor] We can isolate parts of a layer…by use of a mask to either hide or reveal that portion.…When we move the position, scale, or rotation of that layer,…we see that the masks will follow along for the ride.…Sometimes you want to move a layer…independently of the masks that may be on it.…We can achieve that through the use of track mattes.…Track mattes are a tool that has one layer…use the layer above it as a means of hiding…or revealing that imagery.…Here in this example I've got some numbers…and we're just moving up.…I've got two keyframes and what's visible here is…the numbers one through five.…
And if I were to go through and take my rectangle tool…and make sure that my layer is selected,…I can click and drag and create a mask.…And that mask in this instance is…showing only what's inside of it.…Everything else outside of this mask is being cut out.…But you'll notice as I scrub through…that the mask is moving along with the layer.…If I wanted to have the mask move…independently of the layer,…I'm going to need to use track mattes.…
