Pixilation is a stop-motion technique in which live actors are used as a frame-by-frame subject in an animated film, by repeatedly posing while one or more frame is taken and changing pose slightly before the next frame or frames. This technique is often used as a way to blend live-actors with animated ones in a movie.
Early examples of this technique are included in Segundo de Chomón's Cuisine magnétique and Hôtel électrique, both from 1908, and Émile Cohl's 1911 movie Jobard ne peut pas voir les femmes travailler (Jobard cannot see the women working).
