Current issues and concerns

Kieron Niven, Archaeology Data Service / Digital Antiquity, Guides to Good Practice

A common issue with digital video is that the data itself in a ‘raw’ high quality format can be very large e.g. the Wrecks on the Seabed project produced around 40 hours of digital video. If ‘cleaner’ edited versions of video footage are produced, e.g. showing some of the highlights of a dive, then it is important that informed decisions are made on what versions should be preserved and in what quality format. Such decisions should also be weighed against the purpose of the file e.g. is it the sole documentation or merely supportive of other datasets? In addition, DV tape has an increasingly short lifespan and should ideally be migrated to disc based storage. DVDs also have a finite lifespan with hard drives (internal or external) providing the securest medium for storage.
