He grew up in Bad Ischl and later moved to Vienna to study journalism and theatre studies, though he did not complete his degree. In 1985 he began working in the film industry as an assistant to director Paulus Manker and gained practical experience across multiple departments, including sound design, directing, production, and editing for both film and television.

He later collaborated with director Michael Haneke, initially as an editing assistant on *Benny’s Video* (1992) and *71 Fragments of a Chronology of Chance* (1994), before serving as editor on *The Castle* (1997), *Funny Games* (1997), and *Code Unknown* (2000).
