Drawing on my work on the feature film *La Vie de Château*, in this masterclass I propose to review the editing process and explore the role this stage plays — beyond its technical aspects — in the creation of an animated film.

Following on from the script and the storyboard, editing constitutes a third stage of the creative process: whilst it does not allow us to reinvent everything, it does offer the opportunity to test, adjust and rework numerous elements to give the work its final form.
