Rotobrush ( 2 ) is a utility/effect within Adobe After Effects powered by Adobe Sensei. Rotobrushing masks (cuts) out the subject of a video ( using frame by frame refinement with a brush to either
increase or decrease subject area ; hence the name "rotobrush" ). Rotobrushing is also called
rotoscoping. This brings
the power of masking into play within After Effects, and is one of the main reasons many people prefer it over other platforms.
