Track mattes require two layers stacked in a specific order, the one with the…transparency on top, the one with the fill colors underneath, and this pair…needs to be kept together as you start to add in other layers in your composition.…You can go ahead and keep them as pair as you move things around, or it can be…easier to nest this pair into another comp and treat it like a singular footage item.…To demonstrate this I'll go back to my project and I'll open up another comp,…08b-Night Vision*starter.…This comp is a mixture of things you've already seen earlier in this lesson to…make an interesting background movie.…
To go ahead and add this title on top, I'll select the composition, Alpha…Matte*starter, and drag it into this comp.…As a result I have one layer that's acting as a very complex movie, this filled text.…If I want to go back and modify that particular text, I tap the Shift key to…bring up the composition mini flowchart and I can see that my Alpha Matte is…flowing into night vision.…
