English abstract

The audiovisual holdings of archives, libraries and museums are in danger due to the degradation of analogical content recorded on tapes. The article lists the possible damages suffered by videotapes as well as the problems posed by the technical obsolescence of equipment needed to read them. There is an international consensus that digitalization is the best way to preserve videotapes. Digitization is not an easy process considering the complexity of video’s digital file formats, which include rich multimedia wrappers and multiple standards for compressing video and audio. Technical decisions should specifically address the needs of each different service, which is illustrated with a case study on audiovisual recordings from local televisions in Spain.

Spanish abstract

El patrimonio audiovisual de archivos, bibliotecas y museos se encuentra en peligro debido al deterioro de las grabaciones en soportes magnéticos. Se presentan las alteraciones que pueden sufrir las cintas de vídeo, así como las dificultades que representa la obsolescencia de los aparatos necesarios para su lectura. Se considera que la mejor vía de preservación de las cintas de vídeo es su digitalización. Este paso no es fácil dada la complejidad de los formatos de archivos de vídeo digital, incluyendo los contenedores multimedia y los estándares de compresión de vídeo y de audio. Por ello la elección técnica tiene que estar estrechamente ligada a las necesidades de cada servicio. Esta aproximación se ilustra con el caso de los fondos videográficos de las televisiones locales.
