Compositing overview
To create a composite from multiple images, you can make parts of one or more of the images transparent so that other images can show through. You can make portions of a layer transparent using any of several features in After Effects, including the following:
Roto Brush and Refine Edge tools in CC ( See Roto Brush and Refine Edge)
Masks (See About masks and Rotoscoping introduction and resources.)
Mattes (See Track mattes and traveling mattes.)
Painting on the alpha channel (See Paint with the Brush tool.)
The Preserve Underlying Transparency layer option (See Preserve underlying transparency during compositing.)
Keying effects (See Keying.)
To make an entire layer uniformly transparent or semi-transparent, modify its Opacity property.
Layers can also be composited together without modifying the transparency of the layers themselves. For example, you can use blending modes or some of the Channel effects to blend image data from multiple layers into a composite. (See Blending modes and layer styles and Channel effects.)
After Effects also includes the mocha shape for After Effects (mocha shape AE) plug-in, which converts paths from mocha-AE into mattes in After Effects. (See Resources for Imagineer mocha shape for After Effects.)
Adobe Photoshop is an excellent application for performing many compositing tasks, including defining areas of transparency using its selection and painting tools. You can use Adobe Photoshop together with After Effects for optimum efficiency and best results when doing compositing work.
