rotoscoping

This term describes a specialized technical process used in animation and visual effects. In the context of traditional animation, it is prized for producing fluid, lifelike motion that is difficult to achieve through freehand drawing. It carries a connotation of precision and realism, often used to bridge the gap between live-action cinematography and stylized art.

In modern digital compositing, the term refers to the tedious, frame-by-frame task of creating masks. In this professional register, it is often associated with labor-intensive "grunt work" within a post-production pipeline, where the goal is to isolate a subject for the purpose of adding effects or removing unwanted elements from a scene.
