1960s film was typically printed on tri-acetate film base. If#R##N#not preserved properly, such material breaks down at a chemical level,#R##N#which is a non-stoppable process that permanently fuses the film so that#R##N#it essentially becomes a lump of solid plastic. Recently, some precious#R##N#films, such as the only known copy of the earliest surviving episode of#R##N#‘The Morecambe and Wise Show’ have been discovered, but they are#R##N#in poor condition. They will eventually turn into a pool of sticky liquid#R##N#and be gone forever. In this paper, as proof of concept, we use X-ray#R##N#microtomography to provide 3D imaging of a test film of similar vintage,#R##N#and propose an automatic method to extract footage from it.
