Abstract: 

Imagine you could turn back the clock – and your endangered acetate holdings could be kept in a fairly playable condition for the next decades…
Well, there are people working to make this idea come true: Together with high ranking Austrian research institutions, a method to permanently refresh brittle acetate media has been developed and will be available for audio tapes and also cinematographic film material.
The paper briefly describes the mechanisms of acetate degradation as well as related ageing phenomena in audio-visual carrier materials. Possible solutions are discussed and the recently developed restoration and preservation process is outlined, as well as various methods to verify the restoration success. Finally results are presented, covering successfully restored audio as well as motion picture film.
