Hi, I want to combine two video layers using a mask. I'd like to mask certain parts of one layer, so they're transparent, and expose the layer below.
(More specifically, I have slow motion shots of ocean waves. I'd like, for example, the white parts of the waves to reveal a light trail time lapse underneath)
In Premier, I use the Three Way to create masks and define them with luma, saturation and hue. I use this technique constantly for colour correction
Is there a similar way to create masks this the same level of ease in A.E?
I can post examples of my footage if needed.
Effects --> Color Correction --> Tritone
Effects --> Color Correction --> Levels
Assign the result as a luma matte and pre-compose.
