The roto artists role exists more often on special effects work, within the facility houses or on projects that combine the live action and computer graphics.


Rotoscoping is the first skill required by compositors and continues to be part of a Compositor's role.

If the camera is not moving within a shot, rotoscoping may include only one frame however mattes will be needed if CGI interacts with moving people, moving objects or moving background element and in these cases, mattes may be required for every frame.

If live action camera is moving, roto artists trace the relevant areas of every frame within shot so that computer graphics can be combined accurately with live action.
