[email protected] PRESERVATION AND REUSE OF FILM MATERIAL FOR TELEVISION Summary Future television production systems will require easier access to archival film material in an electronic digital form, for both preview and production purposes. In order to meet these requirements, broadcasters will need to transfer large collec- tions of film material – a very time-consuming and expensive operation. Regretta- bly, some of the film material in their vaults may already have started to degrade, due to adverse storage conditions. This document offers comprehensive guidelines to broadcasters on the handling, storage and reuse of motion picture film material for television production, both now and in the future. The telecine transfer process is discussed in detail, with special attention being given to its replay and correction properties. The document also discusses the effects of storage conditions on film material, and the problems encountered when handling endangered, degraded, material in a broadcast environ- ment. There is specific advice on how to check, preserve and store film material. Special attention is paid to the so-called “vinegar syndrome”, which is considered the major threat to the future reuse of acetate-based film material. The EBU working group which produced this document would like to acknowledge Eastman Kodak Company, the Image Permanence Institute and the Rochester Institute of Technology for the facts and figures on motion picture film properties and behaviour that are quoted here.
