Audiovisual Archive Digitalisation

Telefónica Foundation


Telefónica Foundation audiovisual archive preservation and its compatibility with new technologies.

The digitalisation of the Telefónica Foundation audiovisual archive, which stores old film clips that today constitute the historical heritage of a telecommunications company that is nearly one hundred years old, is a delicate commission which has been assigned to Telefónica Servicios Audiovisuales.

The digitization process, divided into several phases, begins with a detailed review of the films, originally recorded in 16 mm and 35 mm formats. The splices are then replaced and any perforations are repaired.

Then, once the old reels and canisters have been replaced by new containers which are suitable for the preservation of film material, the physical cleaning process that precedes the telecine phase begins; a transformation cycle in which the film is projected with specific telecine equipment before being converted into digital format. At this point the basic light setting and audio sync is adjusted.

Then comes the automated digital cleaning process and the creation of an MP4 H264 Full HD file.

Finally, the result undergoes a strict and thorough quality control procedure and the digitalisation process is completed with the editing of the documented files where the technical metadata details and specifications are recorded including, among others: the title, duration, and the date.

Telefónica Servicios Audiovisuales has extensive experience in digitising audiovisual archives, in video, audio and cinematographic formats.
